Does Microsoft Access have told about relationships between tables group of answer choices?

Relationships are like the rules that govern how data is connected in your database. In a well-normalized order-processing database, for example, most likely you’ll have customer information in one table and order information in another table. You want to make sure customers don’t get separated from their orders, right? And you don’t want an order to be created that doesn’t have a valid customer connected to it. The Relationships window is where you go to set these rules so that they apply throughout your database.

If you’ve built an Access query before, you’ll notice that the Relationships window looks a lot like the top part of the Query Builder:

In the Relationships window, you use the commands on the Design tab to add tables to the view, and then you drag fields between tables to set up the relationships. In this example, the relationship allows for multiple orders to be connected to each customer, but it keeps you from creating an order for a customer that doesn’t exist. Once you set up these rules in the Relationships window, they’ll apply to the whole database (for example, if you create a new query, the joins will automatically be set up according to your relationship rules).

Note:  Deleting a table from the Relationships window won’t delete it from your database, nor will it remove relationships that you’ve already established.
