Question
What is the first step in the normalization process?
- A. Create a First Normal table
- B. Identify transitive dependencies
- C. Create an Un-Normalized table
Solution
To address the question regarding the first step in the normalization process, let's break down the options provided.
-
Understanding Normalization: Normalization is a systematic approach to organizing data in a database to reduce redundancy and improve data integrity. The process involves several stages, known as normal forms.
-
Examining the Options:
- A. Create a First Normal table: This step would occur later in the normalization process, after identifying the current state of the data.
- B. Identify transitive dependencies: This is important for determining the relationships among the data but occurs in later normal forms.
- C. Create an Un-Normalized table: This is generally the very first step in the normalization process, as it involves documenting the existing data structure before applying any normalization rules.
-
Conclusion: The first step in the normalization process is to create an Un-Normalized table. This step allows you to see the data in its current state before any transformations for normalization occur.
Final Answer
C. Create an Un-Normalized table.
