Question:

A personnel file contains a record for each employee in an organization. Each record contains four fields: (a) name, (b) division, (c) specialty, and (d) age. Below are four sample records:

Storage Location Name Division Specialty Age 22 Ash New York Audit 30 28 Fox New York Audit 25 64 Luh Chicago Los Angeles Personnel Marketing 29 106 Smith 40

Each of the four fields is expected to be an important search parameter in the personnel application system. Design an index (directory) to invert the preceding file fully.
