The economic justifications of database approach is also an important task before taking any development. The DBMS provide reasonable cost & benefits for developing , implementing & maintain the database system for a given reality in comparison with the economic justification.
The different cost of using database approach is,
1.Cost of software
2.Cost of Procuring software
3.Increment cost of employing application development & database administrator having special skills.
4.Cost of training for the user group application & for the actual users.
5.Incremental cost of designing & Implementing database
The different benefits of using a data base approaches are,
1. Reduction in the salary of users group
2. Reduction in cost due to improved maintenance of data base with the reduced data redundancy.
3. Savings in cost due to the reduction of time in generating the reports.
4. Estimate reduction is the cost due to reduction in delayed information to different user groups.
5. In most of the calculations the dbms will be justified economically for medium & large scale organizations, for small scale organizations one has to carefully analyze the economic justification of the database system before deciding , developing , implementing.
Therefore , the advantages of DBMS are over the file system operations due to the following reasons,
- Reduced data redundancy
- Consistency of data
- Flexibility of the file system
- Enhanced data sharing facility
- Reduced programmable maintenance
- Increase programmable productivity
