Embodiment Construction

[0047] Describe this patent in detail below in conjunction with specific embodiment:

[0048] Data record: It refers to a collection of multiple columns of information, each column contains a specific type of data content, and together represent the completion information of a data record.

[0049] Data table: refers to a collection of data records of the same type, and different data tables can be defined according to different business requirements.

[0050] Data package: Refers to structured business data records, consisting of a set of data tables.

[0051] The above data is usually stored in a relational database.

[0052] figure 2 A schematic diagram of a server data model according to an embodiment of the present invention is shown.

[0053] Introduce the concept of version number to establish version management for data. The data version number is an integer incremental value, which is managed uniformly by the server.

[0054] The purpose of the version number is t...

Abstract

The invention discloses a data synchronization method based on a plurality of end points. The method comprises steps that S1: a client is used to transmit a request to a service end to acquire the latest version information of the data packet of the service end; S2: the client is used to determine a local data changing condition and a data packet version number; S3: when the local data is changedor the version number is smaller than the data packet version number of the service end, the data is synchronized; S4: the data records of the data packet of the client such as adding, changing, and deleting are queried; S5: the changing records of the service end and the client are compared with each other, and then data packet version updating is carried out; S6: the client is used to submit thedata records requiring the changing and the deleting; S7: when the data packet version number of the service end is plus one, the data packet version number of the client is updated to be the same. The synchronization of the structured data between the client and the service end is realized, and technical difficulties such as incremental uploading and version merging of off-line data are solved,and the speed of the data synchronization is accelerated, and therefore user experience is improved.

Description

technical field [0001] The invention relates to a data synchronization method in the computer field, in particular to a multi-endpoint-based data synchronization method. Background technique [0002] With the development of cloud computing and big data technology, more and more software products need to realize cloud storage and synchronization of business data. data support. [0003] To realize synchronous uploading of data, C / S or three-tier mode is usually used to interact with the server in real time. This solution generally does not store data locally, and the acquisition and storage of data on the software interface depends on the server. The cost of product transformation is high. Secondly, when some functional interfaces that need to load and analyze a large amount of data at one time, it is obviously powerless. It has high requirements on the network, requires real-time networking and bandwidth needs to be guaranteed, and is easily affected by network conditions. ...
