Abstract
Real-time database research has reached a point when a practical approach need to be found to combine academic research fruits with real world problems. It is generally believed that the transaction scheduling principles of the traditional database management is too stringent to meet real-time constraints. In this paper, we look at the real world problem and argue that the future will see the proliferation of federated database consisting of distributed heterogeneous subdatabases. We propose the similarity predicate to unify real-time constraints on applications of the federated database system. We then design a real-time SQL engine that sits between the distributed database and the applications that separates the database design from individual user application. The real-time part of the engine benefits from SQL standard and can be scaled from empty to very sophisticated.
