Abstract

Extending expression or query capability of programming languages is one of few current directions of improvement that can be considered domain-neutral. When applied to an existing programming environment, such a work affects the rather foundational elements of the language and thus presents design and integration challenges. This paper describes the implementation of an object-oriented query language integrated as the expression sublanguage into Java and interfacing with the DB4o object-oriented database management system. The language developed offers a promising performance, advantageous to Native Queries and enhanced expressive capabilities of a query.
