The database and application design stages are parallel activities of the database system development lifecycle. In most cases, we cannot complete the application design until the design of the database itself has taken place. On the other hand, the database exists to support the applications, and so there must be a flow of information between application design and database design.
The two main activities associated with the application design stage is the design of the user interface and the application programs that use and process the database.
We must ensure that all the functionality stated in the requirements specifications is present in the application design for the database system. This involves designing the interaction between the user and the data, which we call transaction design. In addition to designing how the required functionality is to be achieved, we have to design an appropriate user interface to the database system.
