                    Creating a Database
                     The first step in creating
                      a database is to create
                      the file that will hold the
                      database objects.
Access  Lesson 2




                     You can use a template
                      that already has objects
                      in it.
                     You can also use a
                      Blank Database
                      template with no
                      objects in it.

                    Creating and Saving a Table
                    In Datasheet View
                     When you create a blank database, Access creates the
                      first table and names it Table1.
                     You can change the name when you save it.
                     To save, click the Save button on the Quick Access

                     The new table name appears on the tab for the table and
                      as an object in the Navigation Pane.

                    Designing a Table in Datasheet
                     After creating a table, you need to tell Access what fields
                      to include.
                     Access creates one field named ID and sets it as the
                      primary key.
Access  Lesson 2




                     A primary key is the field that contains a unique field
                      value for each record.
                     In some tables, this field is called AutoNumber because
                      it automatically adds a unique number.

                    Designing a Table (continued)
                     You can tell that Access created an AutoNumber for the
                      ID field because of the word New in the first records
                      field.
                     Good candidates for being a primary key are

                       Employee numbers
                       Social security numbers
                       Student ID numbers
                     The advantage of setting a primary key is that Access will
                      not let you enter duplicate values for this field in
                      different records.

                     Access assigns a data type as you enter data (Text,

                     You can change the data type for a field by clicking the

                      on the Table Tools Datasheet tab.

                       Any changes made in Design view are automatically
                        updated in Datasheet view when you save the table.

                    Summary
                      Creating a database creates a file that will store
                       database objects. You can create a database using a
                       template or a Blank Database template.
                      You can create a table in Datasheet view by entering
Access  Lesson 2




                       the field names, and then entering the first record.
                      Access assigns the data type as you enter data.
                       Access also creates an ID field to serve as the tables
                       primary key. The primary key is the field that
                       contains unique field values for every record in a
                       table.
