Method and system for obtaining data from a plurality of data pool

Abstract

The present invention discloses a method and a system for acquiring data among a plurality of data sources, and solves the problem that the prior mode for acquiring data by adopting fixed codes is inferior in flexibility. The method includes that entity files are acquired; all properties of the entity are acquired from the entity files, wherein, the entity properties are defined as data sources; the entity properties are analyzed, and an entity structure tree is constructed and displayed; the entity structure tree is inquired, and an entity property value is obtained from a selected data source. Through the present invention, users can define the correlation between the entity properties and the business parameters flexibly according to requirements. When the business parameters run, corresponding property values are drawn out of the entity to constitute business parameters in an active mode of pulling based on the defined correlation, thereby achieving the variability in business control without adopting fixed codes.

Description

technical field [0001] The invention relates to computer data processing technology, in particular to a method and system for acquiring data from multiple data sources. Background technique [0002] In the data processing process of the business application system, it is often necessary to obtain data from multiple data sources for processing. For example, in financial applications, many business documents require budget control, and the budget control system realizes the budget control function by processing the budget data of documents. In the budget control system, budget control parameters required for budget control are defined according to business conditions, which correspond to some attribute information of business documents. When performing budget processing, attribute information corresponding to budget control parameters needs to be obtained from business documents to form budget control Parameters for budget control processing. [0003] For example, the budget...

AI Technical Summary

Problems solved by technology

[0007] Third, the budget business knowledge requirements of developers of various business systems are very high. They must clearly understand the details of many budget modules, otherwise the development cannot be carried out;

[0008] Fourth, the code coupling of various business systems and budget control systems is very strong, making it very difficult to reconstruct the budget system
