Problems solved by technology

In this centralized synchronization process, due to the frequent interaction between the data maintenance server and each data user client, the processing situation is different, and it is easy to make mistakes, which will easily lead to a significant increase in the probability of system errors and reduce the reliability of the system.

Embodiment 1

[0034] Below to Figure 2a In the shown data synchronization system, data use client A to actively perform data synchronization to the data maintenance server as an example, and describe the technical solution of the embodiment of the present invention:

[0035] In the data maintenance server, the data source is specifically stored in the data table of the database, and the data table can be one or multiple ( Figure 2b A specific data table DATA_S) is shown. The data maintenance server also establishes and maintains a change record table (such as a change record table provided by the embodiment of the present invention) Figure 2cAs shown), the change record in it records the change of data in the data table: when the data in a certain data table changes (the type of change can be modification, deletion, or addition), a change record table records a The change situation of this data can specifically include: the identification of the data table where the data is located, th...

Embodiment 2

[0053] The embodiment of the present invention also provides another kind of data synchronous system and synchronous method thereof, in this system, the data maintenance server maintains another kind of change record table (such as Figure 4a As shown), the change of the data in the data table recorded in the change record is: when the data in a certain data table changes, the change record table records the change of the data, which can specifically include: the data The identifier of the data table where it resides, the identifier of the data, and the change type of the data. Data synchronization flow chart such as Figure 4b shown, including the following steps:

[0054] S401: The data usage client sends to the data maintenance server the record number of the change record obtained from the data maintenance server during the last data synchronization. If it is a periodic synchronization, when the set synchronization period arrives, the data can be synchronized using the c...

Abstract

The invention discloses a data synchronization system and a data synchronization method. The method comprises the following steps that: a data user client transmits a record number to a data maintenance server; the data maintenance server determines a newly-added change record according to the received record number and a record number of a change record in a change record chart, and transmits the newly-added change record to the data user client; and the data user client updates local data according to the received change record. The data maintenance server is only required to maintain the change record chart, and is not required to modify the change record chart and perform other operation such as transformation, code modification and the like when the system has a new data user client, so that the work of the data maintenance server is simplified.

Description

technical field [0001] The invention relates to computer communication technology, in particular to a data synchronization system and method between application systems in an integrated environment. Background technique [0002] With the continuous deepening of informatization in government, government agencies, enterprises, universities and other units, the integration of information systems has gradually become a key point. Data integration is the basis of software system integration, data sharing is the main means of data integration, and data synchronization is one of the common technical means for data sharing between different business systems. [0003] A data synchronization system for data synchronization includes: a data maintenance server and a data usage client. Among them, the data maintenance server is used to provide data sources; and the business system that needs these data is called a data usage client. The data usage client obtains the data from the data ...
