....path expressions to simplify the task of formulating queries. Queries in EXCESS work on sets of objects, values or tuples, and they return sets as results. Therefore, the closure property holds. Finally, EXCESS supports aggregate functions which add computational power to the language. OSQL [Ken91] is a database language developed for the IRIS object oriented database system. 6 Its design has been largely influenced by standard SQL. As a result, OSQL serves as an object description, object manipulation and query language. Furthermore, its query part has an SQL syntax. Queries are modeled ....

....was common to bridge the gap. Today, network based file transfer is common. Database access languages, as sql, have been adapted to provide access to data by programs as well as directly to users [Date:89] Extensions to such languages provide access with closure [Ullman:89] and to stored objects [Kent:90]. Experiments to provide access to knowledge sources are in progress as well [Neches:91] However, the inherent differences in the operational paradigms of the two classes still cause a significant impedance mismatch. While performance problems are being mitigated by having better hardware, issues ....
