Conteúdo: | Many of the current database management systems (DBMSs) incorporate the capability of monitoring the state of the database and executing some predefined actions when appropriate events are detected. They are called active DBMSs. Although a fair amount of research has been done in this area, and a few commercial relational DBMSs already offer some of these capabilities, no support for modeling and design of active database behavior is currently provided to take advantage of the new functionalities. The current database design methodology forces the user defer major modeling decisions concerning the active behavior of the database to late stages of the design process, where the semantics of the real-world situations are obscured by the intricacies of the  implementation model. We propose an extension to this methodology, by incorporating active database behavior into the conceptual model in the form of events and rules. The resulting architecture of tools will assist the database designer in the task of specifying analyzing and translating events and rules into executable data definition statements in specific relational DBMSs.
