Question

Discuss the factors that contribute to data redundancy, such as lack of data
normalization, data duplication in multiple tables, denormalization for
performance optimization, and data replication across distributed systems.

Expert Solution

Step 1: Introduction to Data normalization:

Data Normalization:

Data normalization is the process of organizing a database in a way that reduces redundancy and dependency of data. The main goal of normalization is to structure the data in a manner that ensures data integrity and eliminates the possibility of data anomalies during database operations like insertions, updates, and deletions. This process involves breaking down complex data structures into simpler, more manageable forms, and organizing the data into related tables.
