<p><b>Abstract</b>—Querying object evolution in temporal databases is interesting, but neither SQL-like algebraic languages nor general purpose languages take evolution into account. This paper presents a language, called the <it>Event Matching Language</it>, that is specifically designed for querying object evolution. The language is a pattern matching language based on the concept of cursor borrowed from SNOBOL4.</p>
