In Some Business Environments, the Database Designer Also Enters the Data

Multiple Choice

In some business environments, the database designer also enters the data into the database. In Kate’s large banking firm, however, the actual database entries are not made by the database designers.

After perusing the database, Kate has discovered that one data entry operator might enter a telephone number as 555-555-7777, another as (555) 555-7777, and a third as 1-555-555-7777. When multiple data entry operators enter telephone numbers in different formats, it becomes difficult to produce nicely formatted reports or to locate a particular telephone number.

A) case rule
B) field validation rule
C) field format
