Database Reference
In-Depth Information
future. For a pharmaceutical company, conforming to the requirements of the Food
and Drug Administration (FDA) and providing mountains of data for product
approvals may pose a great challenge. Your proposed database system can be robust
and flexible enough to store, sort out, and provide data for FDA approvals.
People.
These are the people in the organization responsible for carrying out
the directives in the long-term business plan. When you interpret the business plan,
you might need additional information as to the proposed data requirements. You
then go to the people who are charged with the execution of parts of the business
plan.
The Database Plan
The database plan covers what must be done in the remaining phases of DDLC. It
sets the tone for the project; spells out the key activities necessary for the success
of the project, and provides a planning document to guide the rest of the project.
Study the following highlights of the activities for preparing the database plan and
for suggestions on its content.
•
Classify your users by responsibility levels, business functions, and geographic
regions. Include the overall, very general nature of the data requirements for
each user group.
•
Adopting a data-oriented approach, consider the business objects and intrinsic
data about them. These are the data that will be stored in the proposed data-
base system.
•
Make preliminary estimates of data volumes. These will help you determine
storage capacities and access paths.
•
On the basis of broad assumptions, prepare very general estimates of hardware
and system software requirements.
•
Take input about future data requirements from the long-term business
plan.
•
Gather data requirements on current functions, applications, and files.
The issuance of a database plan report marks the conclusion of the planning
phase. This planning document gathers the discussions and decisions of the phase;
it sets the tone and momentum for the remaining phases. Here is a typical outline
for a database plan report:
