Querying TSQL2 databases with temporal logic

- Summary
- Metrics

Abstract

We establish an exact correspondence between temporal logic and a subset of TSQL2, a consensus temporal extension of SQL-92. The translation from temporal logic to TSQL2 developed here enables a user to write high-level queries which can be evaluated against a space-efficient representation of the database. The reverse translation, also provided, makes it possible to characterize the expressive power of TSQL2. We demonstrate that temporal logic is equal in expressive power to a syntactically defined subset of TSQL2.
