This book proposed a database modeling approach that improves the representation of the database model. The study also proposed A model transformation framework for the development of database application systems. The proposed framework enables the automatic generation of database schemes and more complete executable codes by incrementally transforming from original models with the tool support. As a result, the productivity and the quality of the software should be improved. The examples and comparisons to other literatures are also illustrated in this dissertation to demonstrate the feasibility of the proposed methods and their advantages over existing approaches.
