SIEVE: An Interactive Visualization and Explanation Tool for An Active OODBMS

摘要

The active functionality is usually incorporated into DBMSs by the event-condition -action (ECA) rule abstraction. Using ECA rules in active database systems for real life applications involves implementing, debugging, and maintaining large numbers of rules. For the effective deployment of active data base systems, there is a clear need for providing flexible user interfaces to cater to different application requirements. Furthermore, experience in developing large production rule systems has amply demonstrated the need for understanding the behavior of rules especially when their execution is non-deterministic. In this circumstance, a graphical debugging and explanation
