Question
Chapter 1, Problem 4P
Program Plan Intro
Anomaly:
- Without normalization, redundancies occur in the table, and it may lead to errors or some sort of inconsistency. These are termed as anomalies.
- Anomalies occur when user wants to update the data in the table.
- There are three types of anomalies namely, Insertion anomaly, Deletion anomaly and Modification anomaly.
Data redundancy:
- Data redundancy is presence of repeated data in the storage device. It consists of duplicate data that is additional to the actual data.
- In this, the data related to a folder can be seen in other folders. For example, file related to science folder can be seen in mathematics or social.
