In developing a computer-based information system, database is needed for storing data. Database that is used in the information system is made based on Relational Database Management System Rules especially Normalization Rule.

The purpose of Normalization is to increase data consistency, to eliminate redundancy, and to increase efficiency in using secondary memory. Normalization Rule focuses in data entities which later are processed to become a database.

In developing a computer-based information system, it is also important to consider the resistant of information system through modification that happens to the objects that are computerized. Modification of objects that are computerized is never considered in normalization rule. As the result, normalization becomes the source of difficulty that causes information system cannot react to the changes of computerized objects.

This research discuss about modification of database created after normalization process, so a database can be more flexible in following the developed computerized objects that can be changed based on the situation.
