When you create a field by entering data in Datasheet view, Access automatically assigns a data type for the field, based on the value that you enter. You can create a new field in Access by entering data in a new column in Datasheet view. You must set a field's data type when you create the field. You set a field's data type in the table design grid, not in the Field Properties pane.Ī field's data type determines what other properties the field has. A field's data type indicates the kind of data that the field stores, such as large amounts of text or attached files.Ī data type is a field property, but it differs from other field properties as follows: You can also set any field property in Design view by using the Field Properties pane. You can set some field properties in Datasheet view. For example, you can set a table's Default View property to specify how the table is displayed by default.Ī field property applies to a particular field in a table and defines one of the field's characteristics or an aspect of the field's behavior.

Before you create tables, consider your requirements and determine all the tables that you might need. Because other database objects depend so heavily on tables, you should always start your design of a database by creating all of its tables and then creating any other objects. For example, a database for a business can have a Contacts table that stores the names of their suppliers, e-mail addresses, and telephone numbers.
