Problems solved by technology

[0004] Aiming at the deficiencies and defects of the prior art, the present invention provides a multi-source heterogeneous data integration system based on data flow technology, so that it can provide a flexible and universal plug-and-play system for different information integration systems in a distributed environment. The data integration system used by the current information integration system needs to be repeatedly developed for data integration functions, and the existing data integration system cannot meet the needs of information systems, as well as the problems of inflexibility and poor scalability, and promote the application and development of data integration

Abstract

The system includes data source management server (DSMS1), data interchange server (DIS), data stream modeling server (DSMS2), and data stream execution and management server (DSEMS). DSMS1 provides interface for outer isomeric data source to realize registration of data source, and transfer the collected data to DIS. DIS manages local mode and global mode as well as stores mapping rules between them, and realizes mapping from local mode to global mode for inputted data. Based on application types ground on global unified view provided by DIS, DSMS2 defines procedure of data stream, generates model of data stream. Connecting outer application system, DSEMS takes charge of starting up execution of data stream, and returns result of flow of data stream to outer application system. Advantages of the invention are: legible modules, as well as dynamic, universal, and flexible features.

Description

technical field [0001] The present invention relates to a system in the technical field of telecommunications, in particular to a multi-source heterogeneous data integration system based on data flow technology for solving distributed multi-source heterogeneous data integration. Background technique [0002] In the information age and the environment of global economic competition, with the continuous development of informatization, various industries, units or institutions, and departments have gradually realized business informatization. However, due to different business and functional attributions, the computer environment used is composed of different platforms, forming a large number of distributed heterogeneous data sources. These isolated heterogeneous data sources are also called "information islands". The work of providing unified representation, storage, query and management of multiple heterogeneous data sources is called information integration. At present, dat...
