Performance of monitoring and control application in Active Database Management Systems
چکیده
In this manuscript, the authors have tried to sort out the performance analysis of monitoring and control application in Active Database Management Systems. Active Database Management Systems (ADBMSs) have been developed to support applications with detecting changes in databases. This includes support for specifying active rules that monitor changes to data and rules that perform some control tasks for the applications. Active rules can also be used for specifying constraints that must be met to maintain the integrity of the data, for maintaining longrunning transactions, and for authorization control. This begins with presenting case studies on using ADBMSs for monitoring and control. The areas of Computer Integrated Manufacturing (CIM) and Telecommunication Nets have been studied as possible applications that can use active database technology. These case studies have served as requirements on the functionality that has later been developed in an ADBMS. After an introduction to the area of active database systems it is exemplified how active rules can be used by the applications studied. Several requirements are identified such as the need for efficient execution of rules with complex conditions and support for accessing and monitoring external data in a transparent manner.
