TASK OVERVIEW

Files

The characters that are stored in a field are called the field

value. When more than one value is associated with a field, the

field is said to contain repeating field values. The field

itself is called a repeating field or group.

Records

A record is a collection of associated fields. Figure 2-12 shows

a typical employee record.

Figure 2-12. Sample Employee Record

An employee record contains the field values that concern a

specific employee.

Files

A file is a collection of records. A file has a name but does

not occupy a specific location in relation to other files. A

file that contains a collection of employee records could be

named "employee." Figure 2-13 shows an example of such a file.
