Method and system for sharing public resource data by multiple information systems

Abstract

The invention provides a method and a system for sharing public resource data by multiple information systems. The method comprises that: a universal query template is defined, wherein the universal query template comprises a universal query template identifier, an inlet parameter and an outlet parameter; a unified resource management system stores the universal query template; and an upper application system of any information system transmits the universal query template identifier and the inlet parameter to the unified resource management system, and the unified resource management system calls the universal query template to query public resource data and feeds back the public resource data according to the outlet parameter. The invention can guarantee that the upper application system of the information system simply, reliably and efficiently share the public resource data.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method and system for multiple information systems to share public resource data. Background technique [0002] In order to support business development, more and more information systems have been established in various industries, and the need for multiple information systems to share public resource data is becoming more and more common. In order to meet this requirement, a unified resource management system is usually established, which uniformly maintains public resource data for sharing by multiple information systems. [0003] However, different resource data do not exist independently of each other, and there are complex correlations between them. Generally, it is necessary to use complex query conditions and associate multi-level resource objects to obtain the data required by business logic; it is also necessary to update multiple associated resource data synchrono...

AI Technical Summary

Problems solved by technology

[0009] 1. In the traditional mode, the stored procedures and transaction control mechanisms that can be completed by DBMS need to be implemented by the upper application system of each information system, which not only has a negative impact on the performance and stability of the system, but also greatly increases the cost of the information system. The complexity of the upper-level application system logic makes it difficult for the unified resource management system to play a practical role

[0010] 2. The amount of data exchanged between the information system, the unified resource management system and the database is too large, which affects system and network performance

[0011] 3. The transaction control of the upper application system of the information system cannot truly guarantee atomicity. Before committing or rolling back, other information systems may access inconsistent resource data, causing logic confusion
