A New Data Integration Method in Distributed Testing Systems
In this paper, a framework to address the issue of data integration in distributed testing system is proposed. The Constraint Integration Grammar (CIG) is proposed to define the local relation sources. One CIG document has three sections: Type Definition Section, Name Mapping Section and Constraint Section. The global schema is a virtual XML source, which can be queried using Xquery. The XML middle ware is developed to rewrite the users query and transform the querying results returned from the DBMS. The experimental results indicate that our framework can integrate the testing data in distributed testing system effectively.
