Methods of reverse engineering and data transformation in determining the multiplicities of associations in object-oriented modeling for database applications

We present an approach of using methods of database reverse engineering and data transformation in determining the multiplicities of associations in object-oriented analysis and modeling (OOAM). OOAM methodology is being used more and more in the development for IT applications of larger sizes. Creating correct object models is becoming important for ensuring that the design for the application is sound. Determining multiplicities of associations among object classes is a key part of creating the object model. The proposed approach is useful for information technology (IT) projects that migrate or integrate old database applications to new database applications. Many IT projects of large scale nowadays are of this type, because companies want to preserve as much as possible the capitals that they invested for old database applications. Many IT projects of large scale more or less involve with migrating or integrating some old database applications.
