Triggered Real-Time Databases with Consistency Constraints

Real-time database systems incorporate the notion of a deadline into the database system model. USUally, deadlines are associated with transactions, and the system attempts to execute a given set of transactions so as to both meet the deadlines and ensure the database consistency. This paper presents an alternative model of real-time database processing in which deadlines are associated with consistency constraints rather than directly with transactions. This model leads to a predicate-baaed approach to transaction management that allows greater concurrency and more flexibility in modeling real-world systems.
