Eliminating the Impedance Mismatch Between Relational Systems and Object-Oriented Programming Language

Relational database management systems have been widely used in industry for many years. Although there has been much research done for developing object-oriented database systems recently, it is believed that relational database systems will still dominate the market for many years. On the other hand, object-oriented programming languages become more acceptable by software developers. It is therefore important to develop appropriate facilities in an object-oriented programming language for accessing and programming relational database systems. Our work described in this paper addresses the interoper-ability issue, in particular the impedance mismatch problem between the query language of a relational database and an object-oriented programming language. This approach is to develop an integrated persistent object-oriented programming environment with access and programming support to relational database systems.
