XML-based multi-source heterogeneous data integration system

Abstract

The invention discloses an XML-based multi-source heterogeneous data integration system. The system comprises an application service layer, a data service interface layer, a data source integration layer and a database system layer; the application service layer realizes expansion of different user applications through an interface provided by the data service interface layer; the data service interface layer realizes real-time interaction operation with the data source integration layer and acquisition of feedback result data, and provides a proper API for the outside; the data source integration layer is used for shielding specific implementation details of distributed data source acquisition operation and responding to an operation request proposed by the data service interface layer; and the database system layer is actually composed of a plurality of relational databases with adjacent or non-adjacent physical positions and is used for providing multi-source heterogeneous data information required by the system.

Description

technical field [0001] The invention belongs to the technical field of big data integration, and relates to an XML-based multi-source heterogeneous data integration system. Background technique [0002] Today, with the rapid increase of information volume, processing distributed data has become a research hotspot. Among them, the integration of heterogeneous data is a key technology for the development of distributed platforms. The application of this technology saves costs and improves production efficiency for enterprises. [0003] At present, most of the research is focused on the research of massive data integration. The data integration framework is mainly aimed at distributed complex systems with complicated technical implementation, and for some systems with relatively simple business and low data volume. Data integration technology research less. [0004] Existing research and development technologies often have the following deficiencies: there are not as many dat...

Problems solved by technology

[0003] At present, most of the research is focused on the research of massive data integration. The data integration framework is mainly aimed at distributed complex systems with complicated technical implementation, and for some systems with relatively simple business and low data volume. Data integration technology research less

[0004] Existing research and development technologies often have the following deficiencies: there are not as many data sources compatible with different distribution forms or different physical platforms as possible, and the later scalability is poor; the necessary security protection strategies cannot be provided for existing data; and appropriate APIs cannot be provided externally; lack of independence
