The document discusses database planning which involves defining: 1. A mission statement that clarifies the purpose and provides a clear path for creating the required database system. 2. Mission objectives that identify specific tasks the database must support. 3. The scope and boundaries of the database system including major user views and how it interfaces with other systems.

4. What are some situations that require
planning?
What happens if you don’t plan?

5. Database planning is carried out
before the rest of the development cycle,
to obtain an idea of the
extent and scope of the project
and the resource requirements.
Typical issues addressed are:
How large will the database be?
What areas of the organization?
How many analysts will it require?
What are the HW/SW needs?

6. – Management activities
– that allow stages of
– database system development lifecycle (SDLC)
– to be realized as efficiently
– and effectively as possible.

7. › Mission statement for the database project
defines major aims of database system.
› Those driving database project normally
define the mission statement.

8. › Mission statement helps clarify purpose of
the database project and provides clearer
path towards the efficient and effective
creation of required database system.

9. › Once mission statement is defined, mission
objectives are defined.
› Each objective should identify a particular
task that the database must support.

10. › Should also include additional information
that specifies the work to be done, the
resources with which to do it, and the
money to pay for it all.

11. › Describes scope and boundaries of
database system, including its major user
views.
› Describes how database system will
interface with other parts of the
organization’s information system.

13. – A centralized database (sometimes abbreviated CDB) is a
database that is
– located, stored, and maintained
– in a single location.
› This location is most often a central computer or
database system, for example a desktop or server
CPU, or a mainframe computer.

15. – A distributed database is a database
– in which storage devices
– are not all attached
– to a common processing unit
– such as the CPU, controlled by a distributed database
management system (together sometimes called a
distributed database system).
