Techniques for Multiple Database Integration

Abstract

There are several graphic client/server application development tools which can be used to easily develop powerful relational database applications. However, they do not provide a direct means of performing queries which require relational joins across multiple database boundaries. This thesis studies ways to access multiple databases. Specifically, it examines how a 'cross-database join' can be performed. A case study of techniques used to perform joins between academic department financial management system and course management system databases was done using PowerBuilder 5.0. Although we were able to perform joins across database boundaries, we found that PowerBuilder is not conducive to cross-database join access because no relational database engine is available to execute cross-database queries.
