To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) A special way of selecting data - This option is incorrect because normalization is not related to selecting data. Normalization is a process of organizing and structuring data in a database.
Option B) The process of adding a primary key to a table - This option is incorrect. While adding a primary key to a table is part of the database design process, it is not the definition of normalization. Normalization involves organizing data to eliminate redundancy and ensure data integrity.
Option C) The process of arranging information stored in a database in a way that removes redundancy and ambiguity - This option is correct. Normalization is the process of organizing data in a database to minimize redundancy and eliminate data anomalies, such as update, insert, and delete anomalies. It aims to improve data integrity and optimize database performance.
Option D) A special way of retrieving data - This option is incorrect. Normalization does not relate to retrieving data. It is focused on organizing and structuring data within a database.
The correct answer is C) The process of arranging information stored in a database in a way that removes redundancy and ambiguity. This option is correct because it accurately describes the concept of normalization.
