Hour 3. Finding and Sorting Data > Overview of Finding Data

Overview of Finding Data

Databases let you manage data: store it, retrieve it, and manipulate it in various ways. In Hour 2, you saw how to store data, and in this hour you'll see how to retrieve it. (Manipulation is covered in Part II, Modifying Templates and Databases.”)

When you store data, you need to store it with an eye to retrieving it. Just as the folders in a file cabinet are set up to help you retrieve data, so, too, a good database is designed with that end in sight. (If your objective was only to store data, not to retrieve it, you could dump everything into one file drawer with no folders in it.)
