Research Of Kernel Data Management Technology For Information Integration System

Information integration is one of hot problems in the domain of database integration research, which needs to integrated data from different sources Information integration provided a unified representation, storage and management for multiple datasource.shielding the differences between a variety of heterogeneous data, providing a unified interface for users to access heterogeneous data sources, allowing users regardless of heterogeneous data models, data extraction and data integration issues. As information integration middleware systems do not store the actual data, and information integration calculations often need to store calculated data. The kernel data management system provide data storage functionality of function calculation module about information integration system.This paper is base on the early design work, which of research group done the organizational structure of the the kernel data management system.Design and Implementation of metadata storage and query functions, data storage and query functions,when functional modules complete to calculation functions about Information Integration System. The realization of data storage has reduced the data storage space and improved processing power for other functional modules of Integrated Systems,when operating the data computation.This paper has completed the major work as follows:(1) The metadata storage management and application of Information Integration System. this paper,base on the design and implementation the organizational structure of the kernel data management system,puts forward a global storage model of metadata about Intergrate System. On this basis, design and implementation of metadata storage and query capabilities.Designing a uniform query access interfaces about application of metadata.(2) Data storage and query function application of the kernel data management system.Based on the data block transfer means between function modules of Information Integration System, designing the ways of storage and query with the data block,and propose specific solutions about factors and existing problems that affect the reliable operation in the system in running existing problems, in the design and implementation process, Improving reliability of operation play a role in promoting on the kernel data management system.
