Assumptions
There are some assumptions that are used in the Express Media database designing like below-
- Staffs are of different types e.g. HR, Sales etc. therefore; a staff type table is created to
store their types.
- Magazine detail should be saved into the database like date of publish etc.
- Types of Payments are different e.g. Cash, Cheque, and Credit Card etc. therefore; a
payment type table is created to store their types.

Database Design Experience
The database assignment has lot of advantages and experiences which I gained while developing
the database of Express Media. Some of them are below-
- It is showing complete knowledge about normalization concept.
- It is showing complete knowledge about pictorial representation of the entities.
- It is showing complete knowledge about database relations.
- It is showing complete knowledge about database integrity.
