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 interoperability 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. 1 Introduction Relational database management systems (RDMSs) and their ex..
