Consider the Relationships
In the
previous lesson, we added a Subdatasheet between two Tables and
Access prompted us to define a relationship. We also created relationships
between the
rest of the Tables with the Relationship Tools.
Why
Does This Matter? This is a relational database. tblReceipt is
related (joined) to tblMovieRented
by a common Key: ReceiptID.
Here is a
preview of how the data in the Tables will look when we complete the
designs:
ReceiptID
2 has one customer: CustomerID 4.
In the
Subdatasheet for ReceiptID 2:
CustomerID
4, has many movies.
This is an
example of a database that is in Third Normal Form.
