[0025] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0026] The terms "first" and "second" in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any of their variations are intended to cover non-exclusive protection. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices. "Multiple" in the present application can mean at least two, for example, two, three or more, and the embodiments of the present application are not limited.

[0027] In the technical solution of this application, the collection, dissemination, and use of data are in compliance with the requirements of relevant national laws and regulations.

[0028] Before introducing the method for updating metadata provided by the embodiment of the present application, in order to facilitate understanding, the technical background of the embodiment of the present application is first introduced in detail below.

[0029] How to update metadata is the key point in building a data standardization system. In the prior art, the scheme for updating metadata is usually determined manually based on the business information to determine the attribute information of the metadata corresponding to the business. For example, a technician can write the metadata corresponding to the business information and the attribute information of the metadata in an Excel file based on the business information, and import the written Excel file into the corresponding business system to maintain the metadata. Alternatively, the technician can directly add, delete or change the metadata and the attribute information of the metadata in the business system to update the metadata. In other words, the existing technical scheme for updating metadata is usually to update the metadata manually.

[0030] However, the manual metadata updating solution has problems such as low efficiency, high uncertainty and inability to update metadata in real time, which needs to be improved.

[0031] In order to solve the above-mentioned defects, the embodiments of the present application provide a method, apparatus, device and medium for updating metadata, which are used to improve the efficiency and accuracy of updating metadata.

[0032] In the present application, the method adopted includes: the server receives a request for updating metadata from a terminal, and the request for updating metadata includes attribute information of the metadata. The data type of the metadata is determined, and the attribute to be verified of the metadata is determined according to the correspondence between the configured data type and the attribute to be verified. The attribute values ​​of the attribute to be verified are verified in sequence according to the attribute standard rule, wherein when there is an attribute value in the attribute to be verified that does not meet the attribute standard rule, the attribute value that does not meet the attribute standard rule is changed to a default value. Standard metadata of the metadata is generated according to the attribute information of the metadata. The standard metadata is sent to the terminal. The standard metadata is updated according to the acquired update indication information.

[0033] By adopting this method, the attributes to be verified of the metadata can be determined according to the data type of the metadata, thereby avoiding the verification of all the attributes of the metadata, improving the efficiency of verifying the attributes of the metadata, and improving the efficiency of updating the metadata. Furthermore, by verifying the attributes according to the attribute standard rules corresponding to the attributes to be verified, the accuracy of verifying whether the attributes meet the requirements can be improved. Generating standard metadata according to the attribute information of the metadata and updating the standard metadata can ensure the maintainability of the metadata in the future.

[0034] In addition, the subject used to execute the method described in this application may be a server, or may be a processing device in a computer system used to execute the method described in this application, such as a processor or a processing module, etc., which is not specifically limited in this application.

[0035] Figure 1 A flowchart of a method for updating metadata provided by an embodiment of the present invention. Taking a server and a terminal as the execution subject as an example, the process may include the following steps:

[0036] S101, a terminal sends a request for updating metadata to a server. Correspondingly, the server receives the request for updating metadata from the terminal. The request for updating metadata includes attribute information of the metadata.

[0037] As an example, a user may trigger the terminal to send a request to update metadata to the server through an input device (such as a keyboard, a touch screen, etc.). Optionally, the metadata attribute information included in the request to update metadata may include at least one of the definition field name of the metadata, the length of the metadata, whether the metadata is a required item, the data type of the metadata, the description value of the metadata, the constraint condition of the metadata, and the default value of the metadata. It is understandable that the attribute information of the metadata may also include other attribute information, which is not specifically limited in this application.

[0038] Exemplarily, the user can input the corresponding attribute information of metadata through the input device of the terminal according to business needs. For example, the user inputs the standard text of metadata to the terminal, and the terminal can analyze the standard text of metadata through a tool with a text analysis function to obtain the attribute information of metadata corresponding to the standard text of metadata. For another example, the user can select or input metadata and / or attribute information of metadata corresponding to business needs in the metadata configuration template. Accordingly, after obtaining the metadata and / or attribute information of metadata, the terminal can generate a request for the metadata according to the metadata and / or attribute information of metadata, and send the request for the metadata to the server.

[0039] Optionally, the request to update metadata may also include an update type. The update type may include adding new metadata, modifying metadata, and deleting metadata. It is understandable that the server can accurately perform corresponding operations according to the update type of the updated metadata. For example, when the update type is to delete metadata, the server can directly delete the metadata from the database. For another example, when the update type is to add new metadata, the server can check for duplicates in the database based on the attribute information of the metadata, and add the metadata to the database if there is no duplicate metadata.

[0040] S102: The server determines the data type of the metadata according to the request for updating the metadata, and determines the attribute to be verified of the metadata according to the corresponding relationship between the configured data type and the attribute to be verified.

[0041] In one or more embodiments, the metadata in the present application may include metadata of multiple different data types. Different data types correspond to different data type identification information, that is, the identification information of a data type is unique.

[0042] After receiving the request to update metadata, the server can determine the data type of the metadata according to the identification information of the data type carried in the request. For example, the information carried in the request to update metadata includes the identification information of the data type of the metadata, and after obtaining the identification information, the server can determine the data type of the metadata according to the correspondence between the pre-stored data type and the identification information. Alternatively, the attribute information included in the request to update metadata includes the data type and / or the data type identification, and the server can obtain the data type and / or the data type identification of the metadata from the attribute information of the metadata.

[0043] Furthermore, the server may determine the attribute to be verified from the attribute information of the metadata according to the correspondence between the data type and the attribute to be verified.

[0044] It is understandable that in the present application, different data types may correspond to different attributes to be verified. Different data types may correspond to the same attributes to be verified. That is, each data type corresponds to an attribute to be verified.

[0045] Exemplarily, the attributes of metadata in this application may have corresponding labels, different labels may correspond to different data types, and the attributes of different labels may be the attributes to be verified of the data type corresponding to the label. For example, the labels corresponding to the attribute information of metadata include a, b, and c, and the data types include A, B, and C. Among them, a corresponds to A, b corresponds to B, and c corresponds to C. The attribute with label a is the attribute to be verified of data type A, the attribute with label b is the attribute to be verified of data type B, and the attribute with label c is the attribute to be verified of data type C.

[0046] Optionally, the attribute to be verified corresponding to the metadata may be set according to business requirements. For example, attribute 1 is set as the attribute to be verified according to business requirements, and when attribute 1 is included in the attributes of the metadata, attribute 1 needs to be verified.

[0047] It is understandable that this method can be used to determine the corresponding attributes to be verified for metadata of different data types without verifying all attributes of the metadata. While ensuring that the attribute values ​​of the metadata attributes meet the set rules, the efficiency of verifying the attributes of the metadata is improved.

[0048] S103, the server verifies the attribute value of the attribute to be verified according to the attribute standard rule.

[0049] In one or more embodiments, the attribute standard rules may be pre-set according to business requirements. For example, the attribute standard rules may be generated according to a pre-set data dictionary. The attribute standard rules may also be determined according to the attribute values ​​of the attribute information of multiple historical metadata. For example, the attribute information of multiple historical metadata may be input into a data model, and the data model outputs the attribute standard rules corresponding to the attribute.

[0050] In one or more embodiments, the attribute standard rules corresponding to the attributes of metadata of different data types may be different. For example, the attribute standard rule corresponding to the data length attribute of metadata of data type A may be 10 bytes, and the attribute standard rule corresponding to the data length attribute of metadata of data type B may be 5 bytes. It is understandable that the attribute standard rules corresponding to the attributes of metadata of different data types may also be the same.

[0051] When the server verifies the attribute value of the attribute to be verified according to the attribute standard rule, if there is an attribute value in the attribute to be verified that does not meet the attribute standard rule, the server can change the attribute value that does not meet the attribute standard rule to the default value. The default value of each attribute can be pre-set. For example, the attribute standard rule of the "Is it required" attribute corresponding to the data type A is "Yes". When the data type of the metadata is A and the attribute value of the "Is it required" attribute is "No", the server can change the attribute value of the "Is it required" attribute of the metadata to "Yes". For another example, the attribute standard rule of the "Length" attribute is that the data length is not greater than 10 bytes, and the default value of the "Length" attribute is 5 bytes. When the attribute value of the "Length" attribute of the metadata is greater than 10 bytes, the server can change the attribute value of the "Length" attribute to 5 bytes.

[0052] Optionally, when there is an attribute value in the attribute to be verified that does not meet the attribute standard rule of the attribute, the server can also send the terminal information that the attribute value of the attribute does not meet the attribute standard rule. For example, when the server is in the process of verifying the attribute to be verified, when the attribute value of a certain attribute to be verified does not meet the attribute standard rule, the server can immediately send the information to the terminal, thereby reminding the user in time. Alternatively, after verifying all attributes, the server can also send all information that does not meet the attribute standard rule to the terminal at the same time, thereby reducing the number of communications between the server and the terminal and reducing the communication volume. Among them, the form of sending the information that does not meet the attribute standard rule can be set according to the importance of the metadata.

[0053] Understandably, when the terminal receives information that the attribute value of a to-be-verified attribute does not satisfy the attribute standard rule, the user can modify the attribute value of the attribute through the terminal, so that the attribute value of the modified attribute satisfies the attribute annotation rule. After the user modifies the attribute value of the attribute, the server can verify the attribute value of the attribute again according to the attribute standard rule to ensure that the attribute value of the attribute satisfies the attribute standard rule.

[0054] In addition, when the attribute to be verified is not included in the attribute standard rules, the server can send a reminder message to the terminal. The user can obtain the prompt information through the terminal and process the attribute according to the prompt information. The processing method is, for example, to determine that the field name and / or identifier of the attribute is wrong, and change the field name and / or identifier of the attribute. The processing method can also be to determine that the attribute is a new attribute, and add the attribute standard rules of the attribute to the attribute standard rules. For example, the attribute standard rules are generated based on the data dictionary. When a new attribute appears, the attribute standard rules of the attribute can be added to the attribute standard rules, and the attribute standard rules of the attribute can be added to the data dictionary at the same time to ensure the consistency and availability of subsequent attribute standard rules.

[0055] S104: The server generates standard metadata of the metadata according to the attribute information of the metadata.

[0056] In one or more embodiments, after the server completes the attribute verification of the metadata, the standard metadata of the metadata can be generated according to the attribute information of the metadata. For example, after the server completes the attribute verification of the metadata, the metadata can be packaged and the metadata can be packaged into standard metadata. Alternatively, the server can process the attribute information of the metadata according to a preset standard metadata template to obtain the standard metadata of the metadata.

[0057] It can be understood that the completion of the attribute verification of the metadata by the server means that the server determines that the attribute values ​​of the attributes of the metadata all meet the attribute standard rules.

[0058] S105: The server sends standard metadata to the terminal.

[0059] In one or more embodiments, after the server generates the standard metadata in step S104, the server may send the standard metadata to the terminal. Accordingly, the terminal receives the standard metadata from the server. The terminal may display the standard metadata generated by the server to the user so that the user can confirm that the standard metadata meets the business requirements and ensure the accuracy of the standard metadata.

[0060] For example, after receiving the standard metadata from the server, the terminal may display the standard metadata to the user in a table form. Alternatively, the terminal may display the standard metadata to the user in a text description form. It is understandable that the terminal may also display the standard metadata to the user in other forms, and this application will not cite examples one by one.

[0061] In one or more embodiments, the server may send metadata to the terminal in the form of a file. When generating standard metadata, the server may generate a standard metadata file that supports the system according to the system type supported by the terminal. The server may also generate metadata files in different formats according to business needs. For example, the format of the metadata file may be "xlsx", "doc", "docx", "pdf", or "txt". It is understandable that the format of the metadata file may also be in other formats, which is not specifically limited in this application.

[0062] Based on this embodiment, the server can generate metadata files that support different systems and different formats according to needs, improve the flexibility of generating metadata files, ensure that business needs are met, and increase the maintainability of metadata.

[0063] S106: The server updates the standard metadata according to the acquired update indication information.

[0064] As an example, the update indication information may be sent to the server according to a preset period. The update indication information may be generated by the terminal and sent to the server according to a preset period. Alternatively, the update indication information may be generated by other devices and sent to the server. For example, the present application may also include a management device, which may periodically send update indication information to the server. Accordingly, the server may receive the update indication information and change the standard metadata according to the update indication information. It is understandable that the update indication information obtained in this manner may be used to indicate the update of multiple standard metadata. That is, the server may update all standard metadata to be updated according to the update indication information.

[0065] As another example, the update indication information may be sent to the server according to the user's instructions. For example, during the execution of step S105, when the user determines that the standard metadata meets the business requirements, the user may send a confirmation indication information to the server through the terminal. The server may generate update indication information for updating the standard metadata according to the confirmation indication information, and change the standard metadata according to the update indication information. It is understandable that the update indication information obtained in this manner may be used to indicate the update of the specified standard metadata. That is, the update indication information corresponds to the standard metadata one-to-one. The server may update the standard metadata according to the correspondence between the update indication information and the standard metadata.

[0066] For another example, a user may send update indication information to a server through a terminal, and the server may receive the update indication information and change the standard metadata according to the update indication information. It is understandable that the update indication information obtained in this way may be used to indicate the update of multiple standard metadata. That is, the server may update all the standard metadata to be updated according to the update indication information.

[0067] The following is an introduction to the server update standard metadata:

[0068] In one or more embodiments, before updating the standard metadata according to the acquired update indication information, the server may also determine a database storing the standard metadata, and perform data format conversion on the standard metadata according to the correspondence between the database type and the data format. The data format conversion may be, for example, encoding conversion, date and time format conversion, etc.

[0069] In one or more embodiments, there may be a correspondence between the data type in the present application and the database used to store metadata. The server may determine the database corresponding to the standard metadata to be updated based on the correspondence between the data type and the database, and store the standard metadata in the corresponding database to facilitate the management of standard metadata of different data types.

[0070] In one or more embodiments, the server may store the standard metadata to be updated in a database with more remaining space according to the usage of multiple databases, thereby avoiding a high storage rate of a certain database.

[0071] In one or more embodiments, the present application may further include a metadata platform. After the server generates standard metadata, the standard metadata may be pre-stored in the metadata platform, or the standard metadata may be sent to the metadata platform. When the server receives the update instruction information, the standard metadata in the metadata platform may be updated to the corresponding database. The specific implementation method of the server updating the standard metadata can be found in the above content, which will not be repeated here.

[0072] In addition, after the server stores the standard metadata in the corresponding database, the user can query the metadata in the database according to the key information, thereby realizing the function of reverse query according to the metadata name or data type and other information. Among them, the metadata query method may include a basic query method and an advanced query method. The basic query method may refer to querying metadata from the database according to pre-set keywords. The advanced query method may refer to the user customizing the query conditions according to the needs. The query conditions are, for example, data type, metadata update time, etc. The user can generate a corresponding query statement according to the customized query conditions to improve the accuracy of the query metadata.

[0073] Based on the above content and the same concept, the present application provides a device for updating metadata. Figure 2 As shown, the device includes a communication module 201 and a processing module 202 .

[0074] The communication module 201 is used to receive a request for updating metadata from a terminal, and the request for updating metadata includes attribute information of the metadata. The processing module 202 is used to determine the data type of the metadata, and determine the attribute to be verified of the metadata according to the correspondence between the configured data type and the attribute to be verified. The processing module 202 is also used to verify the attribute values ​​of the attribute to be verified in sequence according to the attribute standard rule, wherein when there is an attribute value in the attribute to be verified that does not meet the attribute standard rule, the attribute value that does not meet the attribute standard rule is changed to a default value. The processing module 202 is also used to generate standard metadata of the metadata according to the attribute information of the metadata. The communication module 201 is also used to send the standard metadata to the terminal. The processing module 202 is also used to update the standard metadata according to the acquired update indication information.

[0075] In a possible embodiment, the attribute information of the metadata includes: defining the field name, length, whether it is required, data type, description value, constraint conditions, and default value.

[0076] In a possible embodiment, the update indication information is sent to the server according to a preset period. Alternatively, the update indication information is sent to the server according to an instruction of a user.

[0077] In a possible embodiment, before updating the standard metadata according to the acquired update indication information, the processing module 202 is further used to: determine a database storing the standard metadata, and convert the data format of the standard metadata according to the correspondence between the database type and the data format.
