Events can be primitive that is raised by a single database operation, such as insert, delete, and replace. Users can also define composite events that are grouped by multiple primitive events.

Fuzzy logic reflects human nature to express and evaluate the world in a vague manner. This paper describes our approach to incorporate fuzzy logic into XML database systems. The system was built on top of traditional XML databases, while allows the storage of fuzzy data as well as crisp data. The paper describes the structure of the system, starting with the critical architectural component named...
Triggers have played an important role in integrity constraint management for relational database systems. More research projects and commercial systems are working on supporting triggers in XML database systems in recent years. This paper describes our approach to incorporate fuzziness into XML triggers. By adding a thin layer to an existing database, fuzzy expressions can be used within triggers...
