Delta abstractions: a technique for managing database states in runtime debugging of active database rules
2003
IEEE Transactions on Knowledge and Data Engineering
Preserved Fulltext
Delta abstractions provide an additional layer to the database programmer for organizing object deltas according to different language components that induce database changes, such as methods and active ...
An active rule analysis and debugging tool has been implemented to demonstrate the use of object deltas and delta abstractions for dynamic analysis of active rules at runtime. ...
Delta abstractions were specifically developed as an architectural component of an active database runtime environment. ...
