  1. www: this is an excellent start to the task, well done.
    ebi: you have not included the following -
    Interfaces examples and benefits (Forms, Reports and Switchboards).

    www. M1. A excellent piece of work. You have clearly explained the purpose of primary and foreign keys here, and the concept of referential integrity is described accurately.

    www: you have for D1 discussed how potential errors in the design and construction of a database can be avoided. Well done.
