Trans system data exchange structure and method

Abstract

The invention carries out data exchange between at least two systems, which are in remote relation. Each system includes an application server, a database server, multiple computers at client end, and a database. Being in use for providing filtering and servicing operations needed to access data, the application server is located at local area network same as the database server locates at. Access speed of the application server is higher than access speed of computer at client end in process system accesses local system database directly. Moreover, it is not easy to occur online time out for the application server. Http request triggering mode is adopted in application server to supply service for requirement sent out from remote application server. XML format is as data exchange format. Thus, correctness and match of formats are easy to be validated.

Description

【Technical field】 [0001] The invention relates to a cross-system data exchange mechanism, especially a structure and a method for exchanging data among scattered systems while maintaining its security and real-time performance. 【Background technique】 [0002] As large multinational corporations set up branches in cities with different geographic locations around the world, timely information exchange is required between each branch and between each branch and the parent company in order to integrate global information and provide timely, accurate, and detailed information. It is beneficial for decision-makers to make major decisions and arrange the operation and production plans of the entire enterprise reasonably. [0003] The above problems relate to data exchange between different systems, or cross-system data exchange. Such as figure 1 As shown, it is one of the existing solutions for cross-system data exchange. Wherein, it is assumed that system 1 is a local system, ...

Problems solved by technology

[0005] In the above two solutions for cross-system data exchange, the application server 23 of the remote system 2 needs to transmit data to the database server 11 of the local system 1 on a regular basis every day; the database server 11 of the local system 1 allows the application server 23 of the remote system 2 to directly Using SQL database access instructions to access, it is easy to cause the local database server 11 to be overloaded by improper access instructions.

[0006] Aiming at the deficiencies of previous technologies, a new solution for cross-system data exchange is now needed. This new solution should be able to solve the following problems: 1) The access speed is fast, and the situation of online timeout will not occur; 2) Only when necessary There is a data response, and there is no need to send data regularly every day to reduce unnecessary data preparation; 3) Security, no direct access to the database from a remote location is allowed, etc.
