Step 6

Select the tables (Customer and Item) and drag them to designer and you see the following view, where all the tables are placed with their Column Names and whatever you define any Relations between tables, here is the relation between Customer “ID” as primary key and in the table Item “CustomerID” as foreign key, so in this way we can get which customer buys which item.

In the next post we'll see how we can query on this database. And through different queries how we can get our desired data from database.
