Redundancy is reduced in a database table by using the ___ form.a.Normalb.None of the answerc.Speciald.Abnormal

The correct answer is a. Normal.

Explanation

Normalization is a systematic approach of organizing data in a database to reduce redundancy and improve data integrity. The main goal of normalization is to partition large tables into smaller, more manageable ones while ensuring these smaller tables are structured in a way that minimizes duplication of information.

The normalization process involves applying various normal forms (1NF, 2NF, 3NF, and occasionally BCNF and 4NF), each with specific rules to ensure that the data is stored logically and efficiently. By adhering to these forms, redundancy is reduced, which helps in minimizing the amount of storage used and also makes maintenance easier, thereby enhancing the performance of the database.

In contrast, terms like "Special" or "Abnormal" do not correspond to recognized database normalization processes. Therefore, the best answer to the question is "Normal," as it directly relates to the structured methodology used in relational databases to reduce data redundancy.
