Database Reference
In-Depth Information
Less programming.
Application programs do not require elaborate coding for data
retrieval and update operations; the database management system will interpret
simple data access coding and complete the operations. Moreover, separate pro-
grams are not needed for writing most queries and reports. Query tools and report
writers will do the job.
Reduced training costs.
As we have seen above, applications can be standardized
in a database environment. So it becomes easier to train users across applications.
This brings about a general reduction in training costs.
Weighing the Options
Before the business analysts reach the end of the technological and operational fea-
sibility study activities, they collect enough material to list and evaluate the options.
Consider physical hardware, especially the database server machines. Should you
upgrade the existing servers, or switch to a new brand, more powerful but also more
expensive? Weigh the available options at each decision point and make recom-
mendations.
The feasibility study phase concludes with the publication of a comprehensive
report. The study phase not only answers whether the organization is ready for a
database system at all but also makes an assessment of the organization's pre-
paredness. Make suggestions on the available options. Show the costs and benefits
for each option.
