Research Of Information Source Adaptive Problem For Information Integration Application

With the rapid development of computer technology and the rapid advance of information, the amount of information provided in the network is also at a rapid pace. Social organizations or enterprises share their data can enable more people to make better use of existing data resources. But the information for different applications are stored in many different data sources, its data content and data formats vary, and the management system is also different. How to effectively manage these data, shield heterogeneous information and provides a unified interface and transparent access to various information sources, is a headache of enterprises or social organizations.Meanwhile, the security involved in the production system and load problem and needs to be different for different scenarios and real-time requirements to handle access to information sources. At the same time on how to conduct efficient data exchange, improve the efficiency of access to information, is a problem worthy of study. This paper analyzed such information source adaptive problems, studied related issues and put forward my own solution. Finally, an information integration model based on the information source adapter was proposed, and solved related problems.The main work is as following:1) To study the various types of heterogeneity, including heterogeneous information sources and data types of heterogeneity and related issues for the corresponding solutions.2) Provides a unified API with the various information sources, shielding the difference between sources of information, facilitating access to information.3) Analyzed the efficiency of information exchange issue, then, put forward the concept of data block, and effectively solved the efficiency problems.4) Design and implement an information source adapter, and complete the basic functions of the adapter, solved related adaptive problems.
