The Intergration Of Mulit Heterogeneous Data Sources Based On MAS

As development of networks and enlarging scale application of databases, the traditional databases on single machine are gradually switching to multi-database system on multi-node. More and more information has been distributed to different nodes in networks through the mechanism of local cache. So, it becomes the research focus that how to integrate multi data sources distributed in different network nodes into one system and improve the degree of resource shared. A logical model of integration of multi heterogeneous data sources based on MAS is introduced in this paper. Multi heterogeneous data sources can be integrated by the interaction of multi agents in the model. At the end, a prototype is implemented based on the logical model to prove that the model is feasible. The created works of the paper are listed as follows: a. The technique of MAS is used to implement the integration of multi heterogeneous data sources. It can make the system obtain the higher transparency. b. The system can not only provide the method to access all the data sources transparently, but also provide a uniform interface (SDI) for user to manipulate the data and manage the system. c. The system can support the integration of semi-structured/non-structured data sources. The range of information shared is enlarged. d. The system can support redundant services. The reliability and the availability of the system are improved.
