Planning the Database

As a DBA, you must plan:

The logical storage structure of the database and

its physical implementation:

How many disk drives do you have for this? How many data files will you need? (Plan for

growth.)

How many tablespaces will you use?

Which type of information will be stored?

Are there any special storage requirements

due to type or size?
