It is extended and improved on the basis of practical experience of several projects in banks and government offices. They also illustrate a case study of database design using the DATAID approach. The case study refers to a banking environment. This case study is illustrated in their paper “A Case Study of Database Design using the DATAID Approach”. DATAID consists of the following methodological phases:
These phases are followed in the development of the case study of database design.
