The event matching language for querying temporal data
T.S. Cheng, Shashi K. Gadia · IEEE Transactions on Knowledge and Data Engineering · 2002
Querying object evolution in temporal databases is interesting, but neither SOL-like algebraic languages nor general purpose languages take evolution into account. This paper presents a language, called the Event Matching Language, that is specifically designed for querying object evolution. The language is a pattern matching language based on the concept of cursor borrowed from SNOBOL4.
