Abstract

Building object oriented applications which access relational data introduces a number of technical issues for developers who are making the transition to C++. We describe these issues and discuss how we have addressed them in Persistence, an application development tool that uses an automatic code generator to merge C++ applications with relational data. We use client-side caching to provide the application program with efficient access to the data. 1. INTERFACING C++ CLASSES WITH RELATIONAL DATA Object orientation promises dramatic benefits in software productivity, quality and reusability. Yet as with most technology innovations, it requires a significant break from the development practices of the past. Specifically, the difficulty of integrating objects with relational databases has emerged as a major barrier to adoption of object technology by developers who have a significant existing base of hierarchical or relational data. Today, C++ developers have to hand code an interface...
