Comparison and Evaluation of Methodologies for Transforming UML Models to Object-Relational Databases

Application and system modeling have become an important part of many software development projects. The Unified Modeling Language (UML) has been accepted as the general object-oriented modeling language for software systems. In relational database development entity-relationship models have traditionally been used for modeling such systems. It has been acknowledged that relational database management systems need a better representation of the real world than that obtained with the current tabular representation that are derived from the entity-relationship models. Object-oriented modeling is an effective mechanism for representing real world structures. There are many techniques for transforming UML models into object-oriented relational database systems. In this work we will compare, and evaluate methodologies for transforming UML class diagram (CD) models into object-oriented relational databases. This work will focus on the transformations of CDs into a set of statements in SQL:1999. This work will seek to identify the commonality and variability in the methodologies and advantages of the approaches.
