Tables and relationships

To store your data, you create one table for each type of information that you track. Types of information might include customer information, products, and order details. To bring the data from multiple tables together in a query, form, or report, you define relationships between the tables.

1 Customer information that once existed in a mailing list now resides in the Customers table.
2 Order information that once existed in a spreadsheet now resides in the Orders table.
3 A unique ID, such as a Customer ID, distinguishes one record from another within a table. By adding one table's unique ID field to another table and defining a relationship between the two fields, Access can match related records from both tables so that you can bring them together in a form, report, or query.
