Q: What is a common consequence of not normalizing a database?
Solution: Not normalizing a database can lead to data redundancy, which can cause inconsistencies and anomalies.
Steps: 5
Step 1: Understand what normalization means. It is the process of organizing data in a database to reduce redundancy.
Step 2: Recognize what data redundancy is. It means having the same piece of data stored in multiple places.
Step 3: Realize that if a database is not normalized, the same data might be entered in different tables or rows.
Step 4: Know that this can lead to inconsistencies. For example, if you change the data in one place but forget to change it in another, the information becomes incorrect.
Step 5: Understand that anomalies can occur, such as difficulties in updating, deleting, or inserting data because of the redundancy.
