Question: Explain the concept of database normalization and its importance in database design.

Answer: Database normalization is a process used to organize a database structure into tables and columns to minimize redundancy and dependency. The goal is to achieve a database design that is efficient, scalable, and free from anomalies such as insertion, update, and deletion anomalies.

Normalization typically involves decomposing larger tables into smaller ones and establishing relationships between them through keys. There are several normal forms, each representing a higher degree of normalization. For instance, First Normal Form (1NF) ensures that each column contains atomic values, Second Normal Form (2NF) eliminates partial dependencies, and Third Normal Form (3NF) removes transitive dependencies.

Normalization is crucial in database design as it helps improve data integrity, reduces redundancy, and enhances query performance. By structuring data effectively, normalization ensures that the database remains flexible and adaptable to changing requirements.

Question: Discuss the differences between relational and non-relational databases, and provide examples of each.

Answer: Relational databases store data in tables with predefined relationships between them, while non-relational databases use various data models such as key-value pairs, documents, graphs, or wide-column stores. The choice between relational and non-relational databases depends on factors like data structure, scalability, and query requirements.

Relational databases, exemplified by MySQL, PostgreSQL, and Oracle, excel in handling structured data and complex queries involving multiple tables. They ensure data integrity through constraints and provide robust transaction support.

On the other hand, non-relational databases like MongoDB, Cassandra, and Redis offer flexibility and scalability for handling unstructured or semi-structured data. They are well-suited for applications requiring high availability, horizontal scalability, and fast access to data.

Understanding the differences between relational and non-relational databases is essential for choosing the right database solution based on the specific requirements of your application.
