Chapter 12. Database Management > Fields, Records, and Files

Fields, Records, and Files

To begin creating your database, you need to define its structure. Most database management systems provide a screen that prompts you through this procedure. "To define the structure," means to determine the fields that go into your database. A field is a single category of information. Thus, the fields in an address database might include customer name, street address, city, state, zip code, and telephone number (Figure 12-1). Each of the fields needs to be defined individually and to be given a name. You must also tell the database whether the field will contain text information or numbers and what the maximum number of characters per field is.
