Earlier computer applications stored information almost based on existing clerical methods in much the same way as manual files. But the computer's processing speed gave a potential from different sources to produce valuable management information for relating data. The idea becomes visible of the integrated database as a central resource. Data is captured and transmitted to the database close to its origin point then extracted by anyone when ever needed within the organization. It still gives possibly of the strongest motivation for the Database Management Systems introduction in large organisations however for this idea in practice many conditions are attached.

There are some costs related with adopting a Database Management Systems. The actual monetary costs generally differ for a small PC-based system to a large multi-user Oracle system. In the first case the cost will be software with the manual and in the second case the cost will cover training, general documentation, the periodical up gradation; support etc. to the software.
The main cost of the Database Management Systems linked with the work involved in implementing and designing systems to use it. But there is also a trend for the software cost to reflect the hardware cost it is running.
