Localization of Distributed Data in a CORBA-based environment

摘要

Query processing over distributed and fragmented databases is more challenging than doing so in a centralized environment. In a distributed environment, the DBMS needs to know where each node is located. The main role of data localization layer is to localize the query's data using data distribution information. We propose an approach to incorporate the artificial intelligence techniques into a distributed database management system (DBMS), namely to extend the core of a distributed CORBA-based environment with deductive functionalities of the query and view services during the process of data localization. The basic principles and the architecture of the software tool are considered. The implementation and class hierarchy of the object-oriented theorem prover which is built in the core of distributed CORBA-based system are also discussed.
