When using database technology, organizations usually need many database applications to process the data residing in the database. These database applications are typically developed using fourth- or fifth-generation application development environments, which significantly enhance productivity by enabling users to develop database applications faster while producing applications with lower maintenance costs. However, in order to be successful using these fourth- and fifth-generation application development tools, developers must start thinking about the structure of their data first.

It is very important to spend enough time on designing the data model before you start coding your applications.Data model mistakes discovered in a later stage, when the system is already in production, are very difficult andexpensive to fix.
