Abstract

The invention provides a data association analysis method for multiple heterogeneous databases, and the method increases the association query support for multi-data-source data, and helps a user to analyze and discover the association of data between heterogeneous data sources. Better expandability is realized, and access to future novel data sources and novel data of enterprises is supported; data of multiple data sources are synchronized to a target data source, single-point faults can be avoided, and performance expansion can be better carried out by utilizing the target data source; the heterogeneous databases are accessed through the global view on the basis of the intermediate model, the distribution and isomerism differences of the databases are shielded, a unified data view is provided, the problem of mode conflicts among the heterogeneous databases is solved, and efficient access to the heterogeneous databases is achieved.

Description

technical field [0001] The invention specifically relates to a data association analysis method for multiple heterogeneous databases. Background technique [0002] Heterogeneous data is a collection of related multiple data. A heterogeneous database system is a collection of related multiple database systems, which can realize data sharing and transparent access. Several database systems already existed before joining the heterogeneous database system. With its own data array management system, each component of the external database has its own autonomy. While realizing data sharing, each database system still has its own application characteristics, integrity control and security control. [0003] For heterogeneous database systems, data sharing should achieve two points: one is to achieve database conversion; the other is to achieve transparent access to data. The DM3 system, a commercialized database management system with independent copyright, developed by Huazhong U...
