Implementierung einer OQL-Schnittstelle für ObjectStore in Java

This work presents an implementation of an OQL interface for ObjectStore. The aim was to develop a querying tool which uses the advantages of a querying language on an object oriented database. The object query language (OQL) is based on the SQL-92 grammar. It has been developed by the Object Data Management Group ODMG. This work relies on the OQL version published in The Object Data Standard ODMG 3.0. In this implementation an OQL parser, created by the New Zealand Distributed Information Systems Project (NZDIS), was used for parsing the queries. In the next step the queries are built, checked and executed. Finally the OQL interface returns a result set which is exported as XML too.
