Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0032] Please refer to Figure 1 , which is a flow chart of a data processing method provided in an embodiment of the present application. The data processing method is applied to a data processing system, wherein the data processing system can be deployed in a device terminal, and the device terminal can be a laptop or a server, etc., and the present application does not limit this.

[0033] The data processing method comprises the following steps: Step 101: In response to a database opening instruction, detect whether a database configuration file of a first persistent database is configured correctly.

[0034] In some embodiments, the first persistent database is a database that permanently stores data. For example, the first original data stored in the first persistent database may be permanently stored in a persistent storage medium, and the persistent storage medium may include a hard disk.

[0035] In this embodiment, the database configuration file is a file for storing database connection information and other related configurations. The database system can correctly read and parse the information in the database configuration file. The database configuration file contains the parameters required to connect to the database, such as the database address, port number, user name, password, etc. It can also contain other configuration options, such as the database character set, connection pool size, log level, etc.

[0036] In this embodiment, the database configuration file also includes initial data. After a database is configured based on the database configuration file, the data in the database is the initial data.

[0037] The database in this embodiment may include a MySQL database, a SQLite database, an Oracle database, and a DB2 database. In other embodiments, the database may also be other types of database management systems, which is not limited in this application.

[0038] By detecting whether the database configuration file of the first persistent database is correctly configured, it can be determined whether the data processing system can correctly connect to the first persistent database.

[0039] Step 102: When it is detected that the database configuration file is correctly configured, a first temporary database and a first backup database are created, and the first original data stored in the first persistent database is copied to the first temporary database and the first backup database.

[0040] In some embodiments, the first temporary database includes first original data and first operation data, and the first operation data is data obtained after data processing of the first original data. For example, the first operation data may be data added to the first temporary database by a user based on the first original data. The first backup database is used to restore the first temporary database to a historical state. The specific steps of restoring the first temporary database to a historical state using the first backup database are described in detail later, and will not be repeated here to avoid repetition.

[0041] In some embodiments, when it is detected that the database configuration file is configured correctly, it indicates that the data processing system can normally connect to the first persistent database. It is detected whether there is an old first backup database and an old first temporary database. When it is detected that there is no old first backup database and an old first temporary database, a new first backup database and a new first temporary database are created, and the data in the first persistent database is copied to the new first backup database and the new first temporary database.

[0042] When it is detected that there is an old first backup database and an old first temporary database, the old first backup database and the old first temporary database need to be deleted first, and then a new first backup database and a new first temporary database are created, and the data in the first persistent database is copied to the new first backup database and the new first temporary database.

[0043] First, check the database configuration file to avoid errors in the database configuration file, which may cause the database to be unusable. When it is determined that the database configuration file is correctly configured, check whether there is a first backup database and a temporary database left over from the historical period in the data processing system. If there is an old first backup database and an old temporary database left over from the historical period in the data processing system, delete the old first backup database and the old temporary database to avoid the old first backup database and the old temporary database from interfering with subsequent data operations. Finally, the data of the first persistent database can be copied to obtain the first backup database and the first temporary database.

[0044] It should be noted that, when the database configuration file is correctly configured, the first original data stored in the first persistent database is copied to the newly created first backup database and the newly created first temporary database. In the subsequent data process, if data operations such as adding, deleting, modifying, and checking data are required, only the data in the first temporary database is operated, and the data operation is not performed on the first backup database, so that when the data in the first temporary database needs to be restored to the data state of the first temporary database when the database is opened, the data in the first backup database can be directly copied to the first temporary database. The specific steps are described in detail below and will not be repeated here.

[0045] In this embodiment, the first backup database may also be stored in a persistent storage medium, and the first temporary database may be stored in a memory of a device deployed by the data processing system.

[0046] Step 103: In response to the data recovery instruction, the data in the first backup database overwrites the data in the first temporary database.

[0047] Specifically, the data recovery instruction includes a database recovery instruction and a data element recovery instruction. When the data recovery instruction is a database recovery instruction, in response to the database recovery instruction, all the data in the first backup database are overwritten with the first temporary database (referred to as a database recovery operation). When the data recovery instruction is a data element recovery instruction, in response to the data element recovery instruction, some data elements in the first backup database are overwritten with some data elements in the first temporary database (referred to as a data element recovery operation).

[0048] In this embodiment, the specific processes of the database recovery operation and the data element recovery operation are described in detail below and will not be repeated here.

[0049] Step 104: In response to the data persistence instruction, perform persistence processing on the first temporary database to obtain a second persistent database.

[0050] In some embodiments, the data persistence instruction includes a database persistence instruction and a data element persistence instruction. When the data persistence instruction is a database persistence instruction, all data in the first temporary database are persistently stored to obtain a second persistent database (referred to as a database persistence operation). When the data persistence instruction is a data element persistence instruction, some data elements in the first temporary database are persistently stored to obtain a second persistent database (referred to as a data element persistence operation).

[0051] The following are the specific steps for database persistence operations and data element persistence operations: (1) The steps of database persistence operation include: creating a second persistent database, copying all data of the first temporary database to the second persistent database, and deleting the first persistent database.

[0052] (2) The step of persisting the data element includes: detecting whether the persistent data element exists in the second temporary database. If the persistent data element exists in the first temporary database, copying the persistent data element to the first persistent database. Deleting the data element to be persisted in the first persistent database. The first persistent database after the deletion operation is performed is used as the second persistent database.

[0053] In this embodiment, the persistent data element matches the data element to be persisted in the first temporary database. For example, the first temporary database includes data element 1, data element 2, and data element 3. If data element 1 needs to be persistently stored, it is detected whether there is a data element matching data element 1 in the first temporary database. At this time, the data element matching data element 1 in the first temporary database is a persistent data element.

[0054] Step 105: In response to the database closing instruction, the first temporary database and the first backup database are deleted, and the second persistent database is closed.

[0055] In this embodiment, in response to the database closing instruction, according to the persistence requirement, it is confirmed whether it is necessary to persist the data in the first temporary database when closing the database. If it is necessary to persist the data in the first temporary database when closing the database, the data in the first temporary database is overwritten to the second persistent database to store the data persistently. Then, the first temporary database and the first backup database are deleted, and the second persistent database is closed. If it is not necessary to directly delete the first temporary database and the first backup database when closing the database, and close the second persistent database.

[0056] Step 106: In response to the database opening instruction again, copy the second original data stored in the second persistent database to the third temporary database.

[0057] In some embodiments, the third temporary database includes second original data and second operation data, and the second operation data is data obtained by processing the second original data.

[0058] Step 107: In response to the data reset instruction, configure a third temporary database according to the database configuration file.

[0059] Specifically, the data reset instruction includes a database reset instruction and a data element reset instruction. Wherein, when the data reset instruction is a database reset instruction, in response to the database reset instruction, all data in the third temporary database are configured according to the database configuration file, that is, the data in the third temporary database are initial data (referred to as a database reset operation); when the data reset instruction is a data element reset instruction, in response to the data element reset instruction, part of the data in the third temporary database is configured according to the database configuration file, that is, part of the data in the third temporary database is the same as part of the data in the initial data (referred to as a data element reset operation).

[0060] The processes of database reset operation and data element reset operation will be described in detail below. To avoid repetition, they will not be described here again.

[0061] In this embodiment, the database recovery operation and the data element recovery operation are collectively referred to as the data recovery operation, the database reset operation and the data element reset operation are collectively referred to as the data reset operation, and the database persistence operation and the data element persistence operation are collectively referred to as the data persistence operation.

[0062] It should be noted that during the data processing process, according to the data processing requirements, the user can select one or more of the database recovery operation, data element recovery operation, database reset operation, data element reset operation, database persistence operation and data element persistence operation. And the order in which the user operates one or more of the database recovery operation, data element recovery operation, database reset operation, data element reset operation, database persistence operation and data element persistence operation is not limited.

[0063] In order to better understand the content of this embodiment, the recovery, reset and persistence of a database are taken as an example to illustrate it: During the data processing process, the user needs to operate the database in the data processing system. In response to the database opening instruction, the data processing system first detects whether the database configuration file of the first persistent data is configured correctly. When it is detected that the database configuration file is configured correctly, a first temporary database and a first backup database are created, and the first original data stored in the first persistent database are copied to the first temporary database and the first backup database. At this time, the data in the first persistent database, the first temporary database, and the first backup database are all the same.

[0064] The user operates the first temporary database and performs add, delete, modify and query operations on some data in the first temporary database. For example, the user adds some data to the first temporary database. At this time, the data in the first temporary database is different from the data in the first persistent database and the first backup database (the data in the first persistent database and the first backup database are the same).

[0065] After the user performs add, delete, modify and query operations on some data in the first temporary database, the user finds that the data obtained after the add, delete, modify and query operations are wrong and needs to perform a database recovery operation. All the data in the first backup database can be overwritten with the first temporary database (at this time, the data in the first persistent database, the first temporary database and the first backup database are all the same).

[0066] Then, after the user continues to perform add, delete, modify and query operations on the first temporary data, the user needs to perform a database persistence operation to persist the first temporary database to obtain a second persistent database (at this time, the data in the second persistent database is different from the data in the first backup database, and the data in the second persistent database is the same as the data in the first temporary database).

[0067] Then, after the user performs add, delete, modify and query operations on some of the data in the first temporary database, the user finds that the data obtained after the add, delete, modify and query operations are wrong and needs to perform database recovery operations again. All the data in the first backup database overwrites the first temporary database (at this time, the second persistent database is different from the first temporary database, and the data in the first temporary database is the same as the first backup database).

[0068] If the user finishes the data processing operation, the data processing system responds to the database closing instruction and closes the connection between the data processing system and each database. At the same time, the first temporary database and the first backup database are deleted to release the disk storage space of the data processing system.

[0069] The data processing system again responds to the database opening instruction and copies the second original data stored in the second persistent database to the third temporary database and the second backup database.

[0070] After the user performs addition, deletion, modification and query operations on some data in the third temporary database, the user finds that the data obtained after the addition, deletion, modification and query operations are wrong, and needs to restore all the data in the third temporary database to be consistent with the data in the persistent database configured according to the database configuration file when the data processing system first responds to the database open instruction. At this time, in response to the database reset instruction, all the data in the third temporary database is configured according to the database configuration file (at this time, the data in the third temporary database is different from the data in the second persistent database and the data in the second backup database).

[0071] Compared with the related art, the embodiments of the present application have at least the following advantages: After responding to the data opening instruction, first, check whether the database configuration file is configured normally to ensure that the database can be connected and used normally. Then, the first original data of the first persistent database is copied to the first backup database and the first temporary database, so that the first temporary database can be subjected to data operations such as addition, deletion, modification, and query, data recovery, and data reset, thereby avoiding the risk of data loss caused by directly performing data processing operations on the opened database (i.e., the first persistent database) in the related art if the database is subjected to hardware failure, software error, or malicious attack. When it is necessary to perform data recovery operations on the first temporary database, the data of the first backup database can be directly overwritten to the first temporary database. When it is necessary to perform data reset operations on the first temporary database, the first temporary database can be configured according to the database configuration file. In this way, the requirements of data recovery operations and data reset operations can be met during the data processing process. At the same time, if the user needs data persistence operations, the data in the first temporary database is persistently stored so that the data of the first temporary database in response to the data persistence instruction can be directly obtained when the database is opened next time. In this way, during the data processing process, if there is a need for data recovery, data reset, and data persistence, the data processing method can be called directly, avoiding the time-consuming and inefficient problems that occur when users redesign the corresponding operation process.

[0072] Please refer to Figure 2 , is a flowchart of the steps of the database recovery operation provided in the embodiment of the present application. The specific contents of the database recovery operation are as follows: Step 201: Create a second temporary database.

[0073] As described above, the data recovery instruction includes a database recovery instruction and a data element recovery instruction. It is necessary to detect whether the data recovery instruction is a database recovery instruction or a data element recovery instruction. When it is detected that the data recovery instruction is a database recovery instruction, it indicates that a data recovery operation needs to be performed on the database to create a second temporary database.

[0074] Step 202: Overwrite all the data in the second temporary database with all the data in the first backup database, and delete the first temporary database.

[0075] Step 203: Use the second temporary database as a new first temporary database.

[0076] Compared with the related art, this embodiment has at least the following advantages: On the one hand, when various data processing is performed on the first temporary database during the data processing process, the first temporary database can be restored to be consistent with the data of the first backup database at any time according to the current business scenario and logical needs, thereby discarding the data of a series of data modification and change operations on the first temporary database since responding to the database opening instruction. On the other hand, first create a second temporary database, copy the data in the first backup database to the second temporary database, and then delete the first temporary data, and use the second temporary database as the new first temporary database, which can avoid abnormal situations in the data copying process and cause data inconsistency, thereby ensuring data integrity. At the same time, it simplifies data management, avoids data conflicts, and improves data import efficiency.

[0077] Please refer to Figure 3 , is a flowchart of the steps of the data element recovery operation provided in the embodiment of the present application. The specific contents of the data element recovery operation are as follows: Step 301: Detect whether there is a backup data element in the first backup database.

[0078] In this embodiment, it is detected whether the data recovery instruction is a database recovery instruction or a data element recovery instruction. When it is detected that the data recovery instruction is a data element recovery instruction, it indicates that a data recovery operation needs to be performed on some data elements of the database.

[0079] In some embodiments, the backup data element matches the data element to be restored in the first temporary database. For example, the first temporary database includes data element 1, data element 2, and data element 3. If a data recovery operation is required for data element 1, it is detected whether there is a data element matching data element 1 in the first backup database. At this time, the data element matching data element 1 in the first backup database is the backup data element.

[0080] In this embodiment, if the first backup database does not exist, or the backup data element in the first backup database does not exist, there is no need to perform a data element recovery operation.

[0081] Step 302: When it is detected that the backup data element exists in the first backup database, the backup data element is copied to the first temporary database.

[0082] In this embodiment, when it is detected that there is a backup data element in the first backup database, the data element to be restored in the first temporary database is renamed. For example, the renamed data element to be restored in the first temporary database is recorded as tmp. The backup data element is copied to the first temporary database as a new data element.

[0083] Step 303: Delete the data elements to be restored in the first temporary database.

[0084] In this embodiment, tmp in the first temporary database is deleted.

[0085] Compared with the related art, this embodiment has at least the following advantages: On the one hand, when various data processing is performed on the first temporary database during the data processing process, according to the current business scenario and logical needs, some data elements in the first temporary database can be restored to be consistent with the backup data elements of the first backup database at any time, thereby discarding the data of a series of data modification and change operations performed on the first temporary database since responding to the database opening instruction. On the other hand, the data elements to be restored in the first temporary database are first renamed, and after the backup data elements are copied to the first temporary database as new data elements, the renamed data elements are deleted, which can avoid the occurrence of abnormal situations in the data copying process that lead to data inconsistency, thereby ensuring the integrity of the data. At the same time, data management is simplified, data conflicts are avoided, and data import efficiency is improved.

[0086] Please refer to Figure 4 , is a flowchart of the steps of the database reset operation provided in the embodiment of the present application. The specific contents of the database reset operation are as follows: Step 401: Create a fourth temporary database.

[0087] In this embodiment, it is detected whether the data reset instruction is a database reset instruction or a data element reset instruction. When it is detected that the data reset instruction is a database reset instruction, it indicates that a data reset operation needs to be performed on the database, and then it is detected whether the database configuration file exists to ensure that the subsequent data reset steps are smoothly performed. When it is detected that the database configuration file exists, a new temporary database is created based on the database configuration file, and the new temporary database is the fourth temporary database.

[0088] Step 402: configure a fourth temporary database based on the database configuration file, and delete the third temporary database.

[0089] In this embodiment, the data in the fourth temporary database is initial data.

[0090] Step 403: Use the fourth temporary database as a new third temporary database.

[0091] Compared with the related art, this embodiment has at least the following advantages: On the one hand, when various data processing is performed on the first temporary database during the data processing process, the database can be reset to the second data state at any time according to the current business scenario and logical needs, thereby discarding the data of a series of data modification and change operations performed since the database was operated. On the other hand, first create a second temporary database, configure the second temporary database based on the database configuration file, and then delete the first temporary data, and use the second temporary database as the new first temporary database, which can avoid abnormal situations in the data copy process and cause data inconsistency, thereby ensuring data integrity. At the same time, it simplifies data management, avoids data conflicts, and improves data import efficiency.

[0092] Please refer to Figure 5 , is a flowchart of the steps of the data element reset operation provided in the embodiment of the present application. The specific contents of the data element reset operation are as follows: Step 501: Check whether there is a reset data element in the database configuration file.

[0093] In this embodiment, it is detected whether the data reset instruction is a database reset instruction or a data element reset instruction. When it is detected that the data reset instruction is a data element reset instruction, it indicates that a data reset operation needs to be performed on some data elements of the database.

[0094] In this embodiment, the reset data element matches the data element to be reset in the third temporary database. For example, the third temporary database includes data element 1, data element 2 and data element 3. If data reset operation is required for data element 1, it is detected whether there is a data element matching data element 1 in the database configuration file. At this time, the data element matching data element 1 in the database configuration file is the reset data element.

[0095] Step 502: When it is detected that a reset data element exists in the database configuration file, the reset data element is copied to a third temporary database.

[0096] Step 503: Delete the data elements to be reset in the third temporary database.

[0097] Compared with the related art, this embodiment has at least the following advantages: On the one hand, when various data processing is performed on the data elements of the first temporary database during the data processing process, according to the current business scenario and logical needs, some data elements in the database can be reset to the second data state at any time, thereby discarding the data of a series of data element modifications and changes performed since the database was operated. On the other hand, after the reset data elements are copied to the first temporary database as new data elements, the data elements to be reset are deleted, which can avoid abnormal situations in the data copying process and cause data inconsistency, thereby ensuring data integrity. At the same time, data management is simplified, data conflicts are avoided, and data import efficiency is improved.
