When you create an Access database, it's possible (perhaps even likely) that much of your data already exists in electronic form. It could be in another Access database or a database of another software maker. It could be in another Office program, such as Word or Excel. Or it could be on the Internet or in some other computing environment.
It's equally possible that, although you store and manipulate your data in an Access database, you will ultimately use the data in some other milieu. The final destination could be in another program on your own computer, such as a mail-merge document in Word. Or it could be an external audience, such as a client who will look at your billings only if they're in Excel.
