There are three interfaces you can use to enter data into your existing table. You can create a form that will guide the data-entry person while entering or modifying data in the table.
Forms make database access more user friendly and accurate.
You can create a Data Access page to use the web to interact with data in the database. This approach makes it possible to enter and edit data without first using Microsoft Access to open the database. The cursor will initially be positioned in the table's first row and column. With a spreadsheet or word processor, you must give a File-Save command to transfer your work from the computer's memory to disk. But with a database program, whenever the cursor moves off a record that you have changed, the changes will be saved immediately to disk.
