An analysis on the uses of data modeling in database application development / Hafiza Ahmad

Database applications development can be part of a larger project as it's become
increasingly complex each day. It's providing the basis not only for business
applications, but also for searching new market opportunities in this era of
competitive global marketplace. Thus, it is important to model, design and maintain
this complex database. From the survey that being made to the most of the system
developers, it being found that data modeling approach can absolutely assist in
ensuring the accuracy and the consistency of the data required by this database. It
being found that by using data modeling approach, all the data that being required for
the development will be correctly and completely identified. The survey also shows
that most of the respondents used the relational model and the Entity Relationship
Approach as its tool to model their data. There are also the indications from the Chisquare
test of associations where the successful complete data model is dependent on
educational level and development times. As there is an evolution in the data
modeling approach, the developer may decide on which approach they may suit. No
matter on what approach they may use, the importance of data modeling in the
database application development cannot be refused.
