Abstract
Relational database management systems (RDBMS) share a high percentage of the database market. Coupled with client application development tools like PowerBuilder,* and data modeling and design tools like ERwin/ERX, rapid application development is made possible. However, due to the ease of use of these client-server tools, there is a tendency for application developers to quick start their application development process without going through a formal process of database design. Through the use of reverse engineering tools, physical database schemas can be converted into their entity-relationship (ER) model. By looking at the ER model we can evaluate whether the relational database design has been completee or not.
