Question

Indexing is an important ___________.

• A. Method of filing
• B. Preliminary to filing
• C. Aid to filing
• D. Sequel to filing

Answer 1

The correct option is C Aid to filing

Indexing is a way to optimize the performance of a database by minimizing the number of disk accesses required when a query is processed. An index or database index is a data structure that is used to quickly locate and access the data in a database table. Indexes are created using some database columns.

Indexing is an important aid to filing. Filing and indexing are so interrelated that filing without indexing is incomplete and indexing without filing does not exist. Indexing is the process of determining the name, subject, or other captions under which the documents are filed. The index is a guide to records.

Hence, option C is correct.
