entire table object in the database.

3. Show table dialog box will appear. Add all the tables by selecting the table name, and then click button add.

4. Now all the tables will appear in the relationship dialog box.

5. In order to define relationship between table (for table customer and table order), select custID from table customer, then drag it to custID in table order. A line will appear between both of the table. This line indicates the relationship between table customer and table order.

Understanding Types of Relationships

Access 2007 allows for several different types of relationships. These include: One to One (1:1) One to Many (1:m) Many to Many (m:n)

The relationship type you will come across most frequently, and the one created in our biscuit databse scenario, is the One to Many relationship.

One to Many

The One to Many relationship means that data for that field will show up a single time in one table, but many times in the related table.
