The use of a database system results in a noticeable r eduction of costs, particularly in the
development of applications.
The cost savings are achieved due to the following reasons:
– All the people involved in development can use a uniform, non-application-specific
database.
– Preprogrammed functions are provided.
– A data organization which remains stable over the long term solves lots of problems.
Follow-up costs for service and maintenance can be r educed due to the following reasons:
– Data and programs are clearly separated and independent from one another.
– Logical data organization and physical storage form are mutually indepe ndent.
