[0002] Financial market transactions send a large number of messages (such as clearing messages) every day to clear with trading partners, which are characterized by a large number of messages and large amounts of money involved. In actual production environments, changes in transaction information or payment flow information often occur, resulting in the need to resend clearing messages to trading partners. Due to the huge number of messages, when checking messages, it is generally necessary to check the messages at the end before sending them. When an unexpected situation occurs in the inspection system, there is a risk of repeated message sending. In addition, no effective operation is performed on the messages that have been sent repeatedly, resulting in errors in the clearing business and other problems. Summary of the invention

[0038] In order to solve the problem that the repeated messages cannot be effectively checked and revoked in the related art, the present disclosure provides a method, device, electronic device, readable storage medium and computer program product for preventing repeated message sending. It can effectively realize the anti-duplicate check of the sent messages, and can also perform anti-duplicate processing on the repeatedly sent messages, effectively avoiding the problem of repeated message sending. Among them, the method for preventing repeated message sending includes but is not limited to: generating payment flow information according to the acquired transaction information, the payment flow information at least includes the payment flow number and the payment flow version number; generating message content at least according to the payment flow information, the message content has a message type and a message element; judging whether the payment flow information is updated, if the payment flow information has been updated, performing anti-duplicate check on the corresponding message content according to the updated payment flow information, and determining the target message content; performing anti-duplicate processing on at least one message content according to the result of the anti-duplicate check, and sending the target message content to the target object, and the target message content corresponds to the payment flow information.

[0039] According to the embodiment of the present disclosure, the message content is checked for duplicate prevention by judging the update status of the payment and receipt flow information, and the target message content is determined. The target message content can be the newly generated message content or the original message content. The message content is further processed for duplicate prevention according to the result of the duplicate prevention check, and the duplicate message content can be effectively screened out. The method of the present disclosure can effectively avoid the problem of duplicate message content transmission.

[0040] Figure 1 The schematic diagram schematically shows a system architecture to which the method for preventing repeated message transmission of the embodiment of the present disclosure can be applied. It should be noted that: Figure 1The examples shown are only examples of system architectures to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios. It should be noted that the method and device for preventing duplicate message transmission provided by the embodiments of the present disclosure can be used in the fields of computer technology and finance, and can also be used in any field other than the financial field. The method and device for preventing duplicate message transmission provided by the embodiments of the present disclosure do not limit the application field.

[0041] like Figure 1 As shown, an exemplary system architecture 100 to which the method for preventing duplicate message transmission can be applied may include terminal devices 101, 102, a network 103, and a server 104. The network 103 is used to provide a medium for a communication link between the terminal devices 101, 102 and the server 104. The network 103 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0042] The user can use the terminal devices 101 and 102 to interact with the server 104 through the network 103 to receive or send messages, instructions, etc. Various payment client applications or various transaction client applications can be installed on the terminal devices 101 and 102, such as online banking client processing applications, shopping applications, mobile payment applications, public transportation payment applications, investment and financial management applications, etc. (only for example).

[0043] The terminal devices 101 and 102 may be various electronic devices having a display screen and supporting functions such as mobile payment and electronic transactions, including but not limited to tablet computers, laptop computers, and desktop computers.

[0044] The server 104 may be a server that provides various services, such as a background management server that provides support for transaction information or transaction data obtained by users using the terminal devices 101 and 102 (for example only). The background management server may analyze and process the received transaction information or transaction data such as user transaction requests, and feed back the processing results (such as transaction records or transaction data obtained or generated according to user requests) to the terminal device. It may also analyze or process the transaction data sent by the user, and feed back the processing results to the terminal device.

[0045] It should be noted that the method for preventing duplicate message transmission provided in the embodiment of the present disclosure can generally be executed by the server 104. Accordingly, the device for preventing duplicate message transmission provided in the embodiment of the present disclosure can generally be set in the server 104. The method for preventing duplicate message transmission provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 104 and can communicate with the terminal devices 101, 102 and / or the server 104. Accordingly, the device for preventing duplicate message transmission provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 104 and can communicate with the terminal devices 101, 102 and / or the server 104.

[0046] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0047] The following will be passed Figures 2 to 7 The method for preventing repeated message sending of the disclosed embodiment is described in detail.

[0048] Figure 2 The flowchart of the method for preventing repeated message sending according to an embodiment of the present disclosure is schematically shown.

[0049] like Figure 2 As shown, the process 200 of the method for preventing repeated message sending of the present disclosure includes operations S210 to S240.

[0050] In operation S210, payment and collection flow information is generated according to the acquired transaction information, and the payment and collection flow information at least includes a payment and collection flow number and a payment and collection flow version number.

[0051] In an embodiment of the present disclosure, the transaction information may be obtained from the transaction object, for example, and the transaction information includes multiple contents such as transaction time, transaction amount, transaction currency, transaction counterparty, transaction location, etc.

[0052] According to the transaction information obtained from the transaction object, the payment and receipt flow information is generated, and the payment and receipt flow information contains the detailed content of the transaction information, and the payment and receipt flow information also includes the payment and receipt flow number and the payment and receipt flow version number. The payment and receipt flow number corresponds to the transaction information. For example, each transaction information has a unique payment and receipt flow number. After the transaction is completed, the payment and receipt flow number corresponding to the transaction information is generated. The payment and receipt flow number is unique. According to the payment and receipt flow number, the corresponding payment and receipt flow information and the corresponding transaction information and other contents can be obtained.

[0053] The payment and receipt flow version number may be, for example, the version of the payment and receipt flow information. After the payment and receipt flow information is updated, modified or otherwise operated, the payment and receipt flow version number changes accordingly. Based on the payment and receipt flow version number, it is possible to effectively determine whether the payment and receipt flow information is updated or modified, thereby ensuring the accuracy of the payment and receipt flow information.

[0054] For example, when the front-end transaction personnel or the system finds that the transaction information is entered incorrectly, the entered transaction information is modified, and the modification is re-entered into the back-end processing to generate the corresponding payment and receipt flow information. For another example, the back-end transaction personnel modify the payment and receipt flow information, such as the remittance information, the message routing rules, etc. After the modification, the payment and receipt flow version number is updated according to the number of operations. For example, the payment and receipt flow information is generated according to the original transaction information, and the initial payment and receipt flow version number corresponding to the payment and receipt flow information is 01. After the original transaction information is modified, resulting in a change in the generated payment and receipt flow information, or the payment and receipt flow information is directly modified, the payment and receipt flow version number corresponding to the payment and receipt flow information increases in sequence. For example, if the payment and receipt flow information is modified once, the payment and receipt flow version number corresponding to the modified payment and receipt flow information increases to 02. If it is modified again, the payment and receipt flow version number continues to increase to 03, etc.

[0055] In operation S220, message content is generated at least according to the payment and receipt flow information, and the message content includes a message type and message elements.

[0056] In an embodiment of the present disclosure, after the payment and receipt flow information is generated, the message content continues to be generated. Wherein, generating the message content at least includes generating it according to the payment and receipt flow information. For example, when generating the message content, the message content is generated according to the payment and receipt flow information and the application scenario. The message content has a message type and a message element, wherein the message type is determined according to different application scenarios, and different application scenarios have different message types. The message element refers to the specific content contained in the message. When the message is generated, the system automatically decomposes the specific information in the message content, and registers it in the message details table of the database after identification, so as to facilitate the subsequent judgment on whether the message content has changed.

[0057] In an embodiment of the present disclosure, the message content includes a unique identifier corresponding to the payment and receipt flow information. For example, the unique identifier in the message content is composed of the payment and receipt flow number and the payment and receipt flow version number, such as 20211001M12345 / 01, where 20211001M12345 is the payment and receipt flow number, and 01 is the payment and receipt flow version number. Each message content corresponds to the payment and receipt flow information, and the corresponding payment and receipt flow information can be queried or obtained according to the message content. Exemplarily, the corresponding payment and receipt flow information stored in the database is obtained according to the unique identifier in the message content.

[0058] In an embodiment of the present disclosure, after the message content is generated, the unique identifier in the message content can be used to compare with the payment flow information to determine the payment flow information corresponding to the message content, and further obtain the payment flow information stored or updated in the database based on the unique identifier, so as to facilitate subsequent data comparison and other operations.

[0059] In operation S230, it is determined whether the payment and receipt flow information is updated. If the payment and receipt flow information is updated, an anti-duplicate check is performed on the corresponding message content according to the updated payment and receipt flow information to determine the target message content.

[0060] In the embodiment of the present disclosure, it is determined whether the payment and receipt flow information is updated. As mentioned above, when the transaction information is entered incorrectly or the payment and receipt flow information is modified, the payment and receipt flow information will inevitably be changed. At this time, it is necessary to determine the update status of the payment and receipt flow information, for example, the payment and receipt flow information has not been updated or the payment and receipt flow information has been updated. When the payment and receipt flow information has not been updated, it indicates that the payment and receipt flow information has not changed. When the payment and receipt flow information has been updated, it indicates that the payment and receipt flow information has changed. After the payment and receipt flow information is updated, the updated payment and receipt flow information will generate corresponding message content, and it is necessary to perform an anti-duplicate check on the message content. For example, before the payment and receipt flow information is updated, it corresponds to the message content before the update. After the payment and receipt flow information is updated, it corresponds to the updated message content. The message content before the update and the message content after the update are checked for anti-duplicate, so as to determine the target message content, which is the message content to be sent to the target object in the end.

[0061] According to the embodiments of the present disclosure, the update of the payment flow information does not necessarily lead to the update of the message content. First, it is determined whether the payment flow information is updated. If the payment flow information is not updated, the corresponding message content will not change. At this time, the unchanged payment flow information generates the corresponding message content and can be directly sent to the target object. If the payment flow information has been updated, it is further determined whether the message content is updated, that is, the message content is checked for duplicate prevention. This can prevent the repeated sending of the same message, reduce the problems caused by the repeated sending of the same message, and effectively improve the efficiency of message sending.

[0062] In operation S240, anti-duplication processing is performed on at least one message content according to the result of the anti-duplication check, and the target message content is sent to the target object, where the target message content corresponds to the payment and receipt flow information.

[0063] In an embodiment of the present disclosure, after the corresponding message content is checked for duplicate prevention according to the updated payment and receipt flow information, at least one message content is processed for duplicate prevention according to the result of the duplicate prevention check. Wherein, when the message content before the update is consistent with the message content after the update, that is, the message elements and message types in the message content have not changed, there is no need to generate the updated message content, and the message content before the update can be sent to the target object. If the message content before the update has been sent to the target object, it can be selected not to perform the operation. When the message content before the update is inconsistent with the message content after the update, that is, the message elements or message types in the message content have changed, it is necessary to generate the updated message content, send the updated message content to the target object, and if the message content before the update has been sent to the target object, it is necessary to process the message content before the update, such as revoking the message content before the update or deleting the message content before the update, etc. Thereby, the updated message content is sent to the target object as the target message content to reduce the problem of repeated sending of the message content.

[0064] In the embodiment of the present disclosure, the target message content corresponds to the payment flow information, that is, the target message content and the payment flow information are in a corresponding relationship. If the message elements and message types in the message content are unchanged, the target message content can correspond to the changed payment flow information.

[0065] Figure 3 A processing logic diagram of a method for preventing repeated message sending according to an embodiment of the present disclosure is schematically shown.

[0066] Combine the following Figure 3 The processing logic of the method for preventing repeated message sending according to an embodiment of the present disclosure is described in detail.

[0067] like Figure 3 As shown, in the message sending process, it first includes operations S310 to S340.

[0068] In operation S310, payment flow information is generated. For example, the payment flow information may be generated based on the acquired transaction information.

[0069] In operation S320, the message content is generated, for example, according to the payment and receipt flow information.

[0070] In operation S330, the message content is sent to the target object. For example, the message content generated in operation S320 is sent to the trading counterparty through the trading system.

[0071] After the message is sent to the target object, the process proceeds to operation S340 to end the message sending.

[0072] In the embodiment of the present disclosure, when the payment flow information and the specific information in the message content corresponding to the payment flow information are stored in the database of the transaction system, operation S350 is executed to store the data in the database. When the transaction information entry causes the payment flow information, the generated message content, etc. to be updated, the updated payment flow information, the updated message content, etc. will be updated in real time and stored in the database, so as to facilitate the comparison of the data in the database with other data in subsequent operations.

[0073] In operation S360, determine whether the payment and receipt flow version number is greater than the initial payment and receipt flow version number. The payment and receipt flow version number corresponds to the payment and receipt flow information. When the payment and receipt flow information is modified or updated, the corresponding payment and receipt flow version number is incremented in sequence according to the number of modifications, that is, the payment and receipt flow version number is different from the initial payment and receipt flow version number. The initial payment and receipt flow version number is, for example, 01. When the payment and receipt flow version number is greater than 01, it indicates that the payment and receipt flow information has been modified or updated. If the payment and receipt flow version number is greater than the initial payment and receipt flow version number, perform operation S370. If the payment and receipt flow version number is the initial payment and receipt flow version number, it indicates that the payment and receipt flow information has not been modified or updated, and the message content is directly generated according to the payment and receipt flow information.

[0074] In operation S370, the message contents are compared for consistency, that is, anti-duplicate check is performed on the corresponding message contents according to the updated payment and receipt flow information. The anti-duplicate check includes comparing the consistency of the message contents corresponding to the payment and receipt flow information before the update and the message contents corresponding to the payment and receipt flow information after the update as described below. If the message contents are consistent, it means that although the payment and receipt flow information has been updated, the corresponding message contents have not changed. At this time, there is no need to operate the message contents corresponding to the payment and receipt flow information before the update, that is, perform operation S340 and end. If the message contents are inconsistent, it means that the payment and receipt flow information has been updated and the message contents have also changed. At this time, it is necessary to generate new message contents according to the updated payment and receipt flow information, and then perform operation S380 on the message contents corresponding to the payment and receipt flow information before the update to perform anti-duplicate processing. After the anti-duplicate processing, the target message content to be sent to the target object will be determined, that is, operation S330 will be performed to send the determined target message content to the target object.

[0075] Figure 4 The flowchart of operation S230 of the method for preventing repeated message sending according to an embodiment of the present disclosure is schematically shown.

[0076] like Figure 4 As shown, it is determined whether the payment and receipt flow information is updated. If the payment and receipt flow information is updated, an anti-duplication check is performed on the corresponding message content according to the updated payment and receipt flow information. The process of determining the target message content includes operations S231 to S236.

[0077] In operation S231, the payment and collection flow version number of the payment and collection flow information is obtained. If the payment and collection flow version number is greater than the initial payment and collection flow version number, it is determined that the payment and collection flow information has been updated.

[0078] In an embodiment of the present disclosure, the payment flow version number of the payment flow information corresponds to the payment flow information. When the transaction personnel or the transaction system modifies or changes the payment flow information, the payment flow version number is incremented according to the number of modifications. The initial payment flow information generated based on the initial transaction information has a corresponding initial payment flow version number and a unique payment flow number. The payment flow number does not change with the change of the payment flow information, and specific transaction information and other contents can be identified based on the payment flow number. The initial payment flow version number is, for example, 01. When the payment flow information is modified or changed, the payment flow version number will be greater than 01. For example, if it is modified once, the payment flow version number becomes 02. If it is modified again, the payment flow version number becomes 03, and so on. Therefore, whether the payment flow information is updated is determined based on the relationship between the payment flow version number and the initial payment flow version number.

[0079] In operation S232, the corresponding payment and receipt flow number and the current payment and receipt flow version number are obtained according to the updated payment and receipt flow information.

[0080] In an embodiment of the present disclosure, when it is determined that the payment flow information has been updated, the corresponding payment flow number and the current payment flow version number are obtained according to the updated payment flow information. The payment flow number can determine the transaction information corresponding to the payment flow information. The current payment flow version number can determine the number of times the payment flow information has been modified or changed, and then determine whether the payment flow information is the latest.

[0081] In operation S233, the current message content is generated according to the payment and receipt flow number and the current payment and receipt flow version number.

[0082] In an embodiment of the present disclosure, the payment and receipt flow information and the corresponding transaction information and other contents are determined according to the payment and receipt flow number. And the current message content is generated according to the current payment and receipt flow version number. For example, for the payment and receipt flow information with the same payment and receipt flow number, when the original payment and receipt flow version number is 01, it generates the original message content corresponding to the payment and receipt flow version number 01. When the payment and receipt flow information is modified once, the payment and receipt flow version number is incremented to 02, and the message content corresponding to the payment and receipt flow version number 02 is generated. When the current payment and receipt flow version number obtained is 03, the current message content is generated according to the current payment and receipt flow version number 03. That is, different payment and receipt flow version numbers corresponding to the same payment and receipt flow number have different message contents corresponding thereto.

[0083] In operation S234, at least one original message content corresponding to the payment and receipt flow number in the database is compared with the current message content. If the comparison result is consistent, operation S235 is executed, and if the comparison result is inconsistent, operation S236 is executed.

[0084] In the embodiment of the present disclosure, for the generated message content, including the original message content and the current message content, the system automatically decomposes the generated message content, and registers it in the message details table of the database after identification. The message details table is convenient for the same payment flow information (with the same payment flow number) to generate the current message content and compare it with the original message content when it is generated. For example, the current message content is compared with the original message content (and / or the previous version of the message content).

[0085] In the embodiment of the present disclosure, for the same payment and receipt flow number, there may be multiple message contents corresponding to the payment and receipt flow information. The current message content is, for example, the latest generated message content corresponding to the payment and receipt flow information, and the current message content is compared with at least one original message content. The target message content is determined according to the comparison result.

[0086] If the comparison result is consistent, it means that the current message content is the same as the original message content, and there is no need to generate new message content, that is, the current message content may not be generated, or the currently generated message content may be deleted, etc. Then, operation S235 is performed to determine that the original message content is the target message content.

[0087] If the comparison result is inconsistent, it means that the current message content is different from the original message content, and a new message content needs to be generated, and the original message content needs to be processed for duplicate prevention. Then, operation S236 is performed to determine that the current message content is the target message content.

[0088] According to the embodiment of the present disclosure, the payment and receipt flow version number is first used to determine whether the payment and receipt flow information is updated. When the payment and receipt flow information is updated, the message content is checked for duplicate prevention, that is, the consistency of the current message content and the original message content is further compared, and the target message content is determined. The repeated sending of messages can be effectively reduced. At the same time, when the newly generated current message content is consistent with the original message content, there is no need to generate new message content, which can improve the efficiency of message content generation and sending.

[0089] In an embodiment of the present disclosure, the result of the anti-duplicate check includes a comparison result that is consistent and a comparison result that is inconsistent.

[0090] When the comparison results are consistent, the original message content is determined to be the target message content. If the original message content has been sent to the target object, the target message content will no longer be sent. If the original message content has not been sent to the target object, the original message content will be sent to the target object as the target message content.

[0091] Figure 5 The flowchart schematically shows the operation of the original message content when the comparison results are inconsistent according to the method for preventing repeated message sending according to an embodiment of the present disclosure.

[0092] like Figure 5 As shown, performing anti-duplication processing on at least one message content according to the result of the anti-duplication check includes operations S510 to S513.

[0093] In operation S510, if the comparison results are inconsistent, the sending status and receipt status of the original message content are determined.

[0094] In the embodiments of the present disclosure, the sending status includes successful sending, sent, and pending sending. The receipt status includes successful receipt, pending receipt, and failed sending receipt. Among them, successful sending means that the original message content has been sent to the target object, and the transaction object has confirmed the original message content, and the receipt status of the successful receipt is fed back to the sender of the message content. Sent means that the original message content has been sent to the target object, and the target object has not yet processed the original message content. At this time, the receipt status of the pending receipt is fed back to the sender of the message content. Pending sending means that the original message has not been sent from the message sender to the target object, or the original message has been sent to the target object, but the receipt status fed back by the target object is a failed sending receipt.

[0095] In the embodiment of the present disclosure, different operations are performed for different sending states and receipt states of the original message, which specifically include operations S511 to S513.

[0096] In operation S511, if the sending status of the original message content is successfully sent and the receipt status is successfully received, an instruction to revoke the original message content is sent to the target object.

[0097] In operation S512, if the sending status of the original message content is sent and the receipt status is pending receipt, an instruction to delete the original message content is sent to the target object.

[0098] In operation S513, if the sending status of the original message content is to be sent or the receipt status is sending failure, the sending of the original message content to the target object is canceled.

[0099] According to an embodiment of the present disclosure, by performing anti-duplicate processing on at least one message content based on the result of the anti-duplicate check, the probability of repeated message sending can be effectively reduced, while ensuring that the message content sent to the target object is the latest, thereby reducing the problem of clearing errors caused by repeated message sending.

[0100] Figure 6 The schematic diagram shows the processing logic diagram of the operation on the original message content when the comparison results are inconsistent according to the method for preventing repeated message sending according to an embodiment of the present disclosure.

[0101] like Figure 6 As shown, the anti-duplication processing of the original message content includes operations S600 to S616.

[0102] First, in operation S600, when the current message content is compared with at least one original message content and there is no inconsistency, anti-duplication processing is performed on the original message content.

[0103] Next, operation S610 is executed to determine the sending status and receipt status of the original message content, and operations S611, S613 and S615 are executed respectively according to the sending status and receipt status of the original message content.

[0104] In operation S611, it is determined that the original message content is sent to the target object, the sending is successful and a successful receipt is received, then operation S612 is executed.

[0105] In operation S612, the original message content is revoked, and if the original message content still exists in the target object, operation S614 is further performed.

[0106] In operation S613, it is determined that the original message content has been sent to the target object and a receipt to be processed has been received, then operation S614 is executed.

[0107] In operation S614, the original message content is deleted.

[0108] In operation S615, it is determined that the original message content is in a waiting-to-be-sent state or a receipt state indicating that the sending has failed, and then operation S616 is executed.

[0109] In operation S616, the sending of the original message content is canceled, that is, at this time, the original message to be sent or the sending fails will no longer be sent.

[0110] Figure 7 The flowchart of the method for preventing repeated message sending according to an embodiment of the present disclosure is schematically shown, in which the original message content is compared with the current message content.

[0111] In an embodiment of the present disclosure, the process 700 of comparing the original message content with the current message content includes operations S710 to S730.

[0112] In operation S710, a message type and a message element of at least one original message content corresponding to the payment and receipt flow number in a database are obtained.

[0113] In the embodiment of the present disclosure, as described above, when a message content is generated, the system decomposes the message content and registers it in a message detail table in a database after identification, wherein the message content has a message type and message elements.

[0114] In operation S720, the message type and message elements of the current message content are obtained.

[0115] In operation S730, the message type and message elements of the original message content are compared one by one with the message type and message elements of the current message content.

[0116] In an embodiment of the present disclosure, the message type and message element corresponding to the original message content are compared one by one with the current message type and message element. When at least one of the message type or message element is different, it is determined that the current message content is inconsistent with the original message content. In this embodiment, the receiving and paying flow numbers in the receiving and paying flow information corresponding to the original message content and the current message content are the same.

[0117] In an embodiment of the present disclosure, the method for preventing repeated message transmission further includes: acquiring payment flow information corresponding to the message content in a database according to the unique identifier, wherein the message content includes the unique identifier corresponding to the payment flow information.

[0118] Exemplarily, after the message content is generated, the message content includes a unique identifier corresponding to the payment flow information. By reading the unique identifier, the payment flow information corresponding to the message content in the database can be obtained, which is convenient for obtaining detailed data or performing data comparison and other operations.

[0119] In the embodiment of the present disclosure, the unique identifier corresponding to the payment flow information included in the message content is composed of at least a payment flow number and a payment flow version number. The corresponding transaction information is determined according to the payment flow number, and the corresponding payment flow information is determined according to the payment flow version number.

[0120] In an embodiment of the present disclosure, the method for preventing duplicate message transmission also includes determining the correctness of the payment and receipt flow information after generating the payment and receipt flow information. For example, the specific content of the payment and receipt flow information can be determined manually or automatically by a preset program to ensure the accuracy of the information and reduce the probability of error.

[0121] In the embodiment of the present disclosure, the payment flow number is uniquely bound to the transaction information, and the payment flow version number changes with the update of the payment flow information.

[0122] In the embodiment of the present disclosure, after the payment flow information is updated, the information in the database is updated synchronously with the payment flow information, thereby ensuring that in the above-mentioned process of comparing the original message content with the current message content, the data in the database called is accurate.
