As your customer base increases or other new data becomes available for your database, you will definitely be adding records to the various tables in the database. New records are inserted automatically. As soon as you begin to enter data into a record, a new blank record appears at the bottom of the table.
This process is re-created every time you complete a record and then start a new record. Inserting information into the first field of the new record inserts another new record below the one you are working on.
You can't insert new records between existing ones or at the top of the table. New records are always entered at the bottom of the table, below the last completed record.
