Introduction to Databases

Learn about Access 2003 databases and understand how they work in this free lesson.

Organizing our world

What if you needed to pull out only contacts who represent family members? Perhaps another family member might want this information. You would have to flip through every page of your address book and write down the exact same information onto another piece of paper, or perhaps even another address book. This is time consuming. Contact records are duplicated. A change to one phone number means it has to be changed in two or more places: in the address book and anywhere else where you recorded the information.

Address Book Entry

Over time, your address book will become old and worn. The records in it will be crossed out and changed as people move from one place to another or change their phone numbers. You need a new address book. And then you need to rewrite all pf that information again into a brand new book.

It's a lot of work.

What you need is a database.
