With rapid development of computer and network techniques, the information requirements for many enterprise departments are increasing ceaselessly. At present, many institutions or sections of an enterprise use computer for managing business or office affairs. However, "information isolated island" is exist for many reasons. In order to share the resource in an enterprise and make a decision in time and correctly, it becomes more and more urgent to integrate the information of all systems in existence.Firstly, some basic concepts, methodology and techniques of data integration are introduced in the paper; some commonly used methods of data integration are analyzed deeply and the main characteristic and data integration mode of each method is compared. Then, a central database based data integration model is presented in the paper according to actual requirements of fine or small enterprises.The function, implementation mode and incremental data updating strategy adopted by the model of each element in the model presented in the paper are discussed in details. Some critical techniques are analyzed and a solution scheme is presented which fits for data incremental collection based on trigger, mechanism of communication agent based on Socket and data exchange based on XML. It is feasible to implement a real-time data integration system base on the model presented in the paper which can bring convenience to implement the global application and some decision-making analysis of an enterprise.The system we constructed is using now. Practical running shows that the real-time data integration is correct and fast, which provides a quite well basement for future business application and reaches the target anticipated.
