Embodiment Construction

[0052] The present invention is described in detail below in conjunction with accompanying drawing:

[0053] The invention provides an XML-based heterogeneous relational database data integration method that is suitable for small and medium-sized enterprises, is cheap and efficient, has strong scalability and portability, and crosses operating systems and database platforms.

[0054]The method is based on a self-compiled computer program for data integration of a heterogeneous relational database based on XML. The computer program runs in a network environment and is based on a self-defined Java and XML data type system with dynamic data source management. , Integrated task configuration and optimization, data extraction and integration, and result persistence are cross-platform data integration software systems. At the same time, the method provides the solution to the new database product in the software system, and the processing steps of the specific data integration appli...

Abstract

The invention discloses a data integration method and system of a heterogeneous relational database based on XML (Extensive Makeup Language), which aims to solve the problem that large amount of data information cannot be utilized efficiently. The method comprises the steps of: acquiring data integration requirement and integration pre-preparation; executing a database product which adds new support to the system if integration application involves in the new database product; adding a data source related to integration; generating a search request configuration file; entering persistent parameters on a persistent parameter configuration interface of the system; selecting an integration plan file on an integration plan executing interface of the system and executing the integration plan; waiting processing of a software system and repeating the steps 4 to 6 till all integration tasks are completed. The data integration system of the heterogeneous relational database based on XML is a functional module structure consisting of an integration task manager, a data source manager, a query decomposition optimizer, a data extractor, a result aggregator and a result persister.

Description

technical field [0001] The present invention relates to a data integration method in the field of information technology, more precisely, the present invention relates to a data integration method for an XML-based heterogeneous relational database. A data integration system for constructing relational databases. Background technique [0002] In recent years, many enterprises have accumulated a large amount of data along with the development of business. However, due to the distribution, heterogeneity and independence of database systems within and among enterprises, the formation of "information islands" prevents large amounts of data from being used correctly and efficiently. Therefore, solving this practical problem is of great significance to the operation and development of enterprises. [0003] At present, specific industries such as banking and telecommunications already have mature methods and tools for data exchange and data integration. Small and medium-sized ent...
