Embodiment Construction

[0014] like figure 1 Shown is an implementation environment diagram of the unstructured data synchronization system and method of the present invention. The system is composed of enterprise information system nodes scattered in different geographical locations, specifically including a main node 110 and several branch nodes 120, 130 (only two are shown in the figure). These nodes are connected through enterprise intranet 140, and all adopt three-layer (or multi-layer) structure: a database server (113, 123 or 133), an application server system (112, 122 or 132), and scattered clients ( 111, 121 or 131). The composition of each node will be introduced below by taking the master node 110 as an example.

[0015] The master node 110 includes a database server 113, an application server system 112 and several clients 111 (only one is shown in the figure). The database server 113 is used to store all structured data related to the enterprise, and is responsible for managing the r...

Abstract

Digest information of non-structured data is stored in structured database, and digest information is synchronized first. Then, based on need, synchronous operation of non-structured data is carried out. Thus, under relative lower communication traffic, realtime synchronization of non-structured data is realized. The method includes following steps. Digest information lists of non-structured data are synchronized between database servers at several branch nodes. The first branch node sends message of synchronization request to second branch node containing non-structured data. The second branch node receives the message of synchronization request, and transfers newest version of non-structured data to first brunch node. The second brunch node stores information of the synchronization procedure on a digest information list of database server in second branch node.

Description

【Technical field】 [0001] The invention relates to a data synchronization system and method, in particular to an unstructured data synchronization system and method using a two-step synchronization method. 【Background technique】 [0002] With the development trend of economic globalization, a large number of large enterprise groups that cross regions and borders have emerged. The branches of these enterprise groups are distributed all over the world, and the branches need to share information for joint operations. Therefore, how to manage and control its information to realize the sharing of enterprise resources has become an important part of the operation of such enterprises. The development of information technology has made cross-institutional and cross-regional data access and collaboration possible. At present, in order to improve the efficiency of data access and reduce the loss of failures, enterprises generally use distributed data management systems. [0003] A d...
