Problems solved by technology

When users put forward new requirements, it is necessary to manually maintain and improve the platform, which is a long and complicated process
At present, there are some integration methods that support users to import and manage databases. However, these integration methods can only achieve preliminary integration. In the integrated search, the most basic search fields are returned to the user. When the user has further requirements for the detailed content and structure of the knowledge When using the database, it often adopts the method of automatically obtaining the database association table to return some possibly relevant information to the user, and the information often has the characteristics of low accuracy and lack of organization.

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0027] See attached figure 1 , the Web service integration middleware system system includes data warehouse, integrated data layer and application interface from bottom to top. Among them, various heterogeneous data sources at the bottom constitute the data warehouse of the system; the integrated data layer adopts middleware technology to encapsulate the business logic of the heterogeneous database integration system; various application programs and corresponding access interfaces constitute the application interface of the system .

[0028] The system adopts the B / S mode and constitutes a client / server three-tier architecture. Adopting this design has the following advantages: easy install...

Abstract

The invention relates to a system used for ensuring completeness of data integration in a heterogeneous database system. In order to ensure the completeness of the data integration in the heterogeneous database system, a data integration layer is designed; a conversion function is provided for data from a heterogeneous data source; and a data integrity requirement is met.

Description

【Technical field】 [0001] The invention belongs to the technical field of knowledge management and data integration. 【Background technique】 [0002] With the advent of the era of big data and the in-depth development of the knowledge economy, enterprises, research institutes and other research and development and production institutions pay more and more attention to the management of knowledge, implement a lot of information software, and generate a large amount of data, which are stored in different in the database. However, knowledge that is relatively independent and lacks organization is difficult to exert its full value, so it is necessary to integrate these resources effectively through the integration of heterogeneous databases. [0003] These databases have the characteristics of system heterogeneity and structure heterogeneity, and are called heterogeneous databases. Conventional integration methods mostly adopt customized methods to integrate existing heterogeneo...
