Abstract
A system that improves performance of a centralized DBMS is provided. The improved performance is realized by distributing part of the DBMS's functionality across multiple computers in a client/server environment. The distribution of the DBMS's functionality is performed by a mechanism known as the navigational agent, which is detached from the DBMS. The navigational agent integrates the centralized DBMS into a client/server environment so that performance improvements can be achieved by distributing a portion of the functionality of the centralized DBMS and some of its database objects to client computers. A database object is a unit of data in the database such as one or more fields of a record, one or more records, or one or more tables. By distributing part of the DBMS's functionality and some of the database objects to client computers, transactions can be performed on the client computers without having to access the server computer on which the database resides. Since these transactions are performed by the client computer instead of the server computer, the bottleneck created by the DBMS on the server computer is reduced, which improves performance of both the DBMS and programs interacting with the DBMS.
