Event-Oriented Data Models and Temporal Queries in Transaction-Time Databases Carlo Zaniolo University of California, Los Angeles Abstract—Past research on temporal databases has primarily focused on state-based representations and on relational query language extensions for such representations. This led to many different proposals that had did not succeed in making a signif- icant impact on SQL-compliant DBMS. More recently however, there has been significant interest and progress on event se- quences, leading to vendor-proposed extensions of SQL standards for pattern queries based on Kleene-closure expressions.
