A Second Example

This chapter expresses the schema and some of the queries of the extensive consensus test suite for temporal relational query languages [Jensen 1993]. The test suite is not related to performance issues, but has a semantic focus and is intended to be an aid in evaluating the user-friendliness of temporal query languages. An attempt is made to express the schema and queries in TSQL2 in a convenient and natural fashion, as an informal evaluation of that language’s user-friendliness.
