The Placement Center of the Atlanta University organizes interviews of the students with the companies around the country. A database management system is being developed for signing up and preparation of interview schedules on the IBM PC. The dBASE II database manager is used for creating the database and writing the programs to access the database. In the first phase, a pilot database management system was tested and suggestions were collected. This system us called Model I. In this model, the database exists in the third normal form. The students and the Placement Office personnel found this system to be not too user-friendly. Then Model I was modified to make the system more user-friendly and cut down the user-time. The modified system is called Model II, where the database is the unnormalized form.

This study makes a comparison of Model I and Model II and analyzes the advantages and disadvantages of both the models and concludes that in order to make a database system user-friendly and cut down the user-time, sometimes a database may have to be designed in the unnormalized form; knowing that a database in unnormalized form has insertion, deletion and update anomalies.
