At present, the synchronization technology between databases is widely applied to servers, and the main purpose of the synchronization technology is to improve the system capacity, the system response speed, the reliability and the like. The database architecture between servers includes a master slave architecture, and the current synchronization operation refers to the synchronization of data from the master database to the slave database, and is a one-way operation, and the master database and the slave database have the same data except for delay.
The database synchronization techniques of the client and server architectures are very different from those of the master and slave databases. First, the database of the client only contains shared data among users and data related to the current user, and the server only contains the shared data and data of all users. The synchronization operation is bi-directional, i.e., the operation may be from the client to the server or from the server to the client. In the client and server architecture, the data of the application program on the client is stored locally, so that the application program is quick in response, good in user experience and capable of being used offline. For the above reasons, more and more applications are beginning to use client and server architectures, such as mobile phone applications, desktop applications, increasingly popular single web applications, and offline viewable mail applications.

The client middleware 2013 may also update the UI according to data received from the server 202. The server 202 comprises a server database 2022, the server database 2022 comprising common data and all user data. The server 202 also includes server middleware 2021, and the server 20221 receives the data of the client 201 and performs the same part of the data on the server database 2022.
In this embodiment, the synchronization request includes first data flow information, and the first data flow information includes a data flow identifier and a corresponding first application level.
In this embodiment, when performing a data operation on data in a database, the corresponding data content is adjusted according to the data operation, and the data operation is converted into a data change record, where the data change record includes an operation serial number, an operation name, a data form name, and an operation data set. Referring to fig. 3, fig. 3 is a schematic diagram of a data change record according to an embodiment of the present invention. As shown in fig. 3, in the case that the data operation is person, age ═ 30person, save (), the data change record corresponding to the conversion is: the sequence number is an increasing sequence, and the sequence number of the data change record corresponding to the latest data operation of one data is greater than the sequence number of the data change record corresponding to the previous data operation. The op represents an operation, namely the Chinese meaning of English operation, the operation comprises an adding operation, an updating operation, a deleting operation and the like, the adding operation can be represented by create, the updating operation can be represented by update, and the deleting operation can be represented by delete. record represents the name of the data change record, corresponding to the name of the data form. data represents data used by data operation, and is a set of one key and a corresponding value, and the set must include a primary key id. Each key in the data used by the data operation corresponds to the value of one field of the form in the database.
In this embodiment, after converting the data operation into a data change record, the database may be synchronized according to the data change record. Specifically, referring to fig. 4, fig. 4 is a schematic diagram of data operation according to an embodiment of the present invention. As shown in fig. 4, the data change is recorded as: sqe, the op is 1, the record is person, the data is (id is 1, age is 30), according to the data change record, the form with the form name being person is searched, the age field corresponding to the primary key id with the primary key id being 1 is determined from the person form, the age field corresponding to the primary key id with the primary key id being 1 is updated to 30, thus the database can be updated according to the data change record, and the purpose of updating the database is achieved.

For example, the client uses the name of the data stream as a data stream identifier, and maps the data stream identifier with a first application level of the data stream to obtain first data stream information, where the first application level is a maximum operation sequence number in a data change record of the data stream corresponding to the data stream identifier and stored by the client. For another example, the server uses the name of the data stream as a data stream identifier, and maps the data stream identifier with a second application level of the data stream to obtain second data stream information, where the second application level is a maximum operation sequence number in the data change record of the data stream corresponding to the data stream identifier and stored by the server.
