  1. www: this is an excellent start to the task, well done.
    ebi: you have not included the following -
    Examples of the main features of a database (Tables, Fields and Records).
    Descriptions of data types.
    Interfaces examples and benefits (Forms, Reports and Switchboards).

  2. www: the above post shows you understand referential integrity and the purpose of primary keys in building the relationships between tables and also how potential errors in the design and construction of a database can be avoided. So M1 and D1 are achieved.
    ebi: you make the changes listed in my above comment.
