Relational Databases

In the world of software development, relational databases play a pivotal role in managing and organizing vast amounts of data efficiently. Relational databases store data in tables that are connected through relationships. Each table represents an entity, such as a user or a product, and each row in the table represents a record. Columns in the table correspond to attributes or fields of the entity.

Relational databases offer several advantages:

• Data Integrity: Relational databases enforce rules and constraints that ensure the integrity of data. For example, a primary key constraint ensures that each row in a table is uniquely identified.
• Querying Flexibility: Using Structured Query Language (SQL), you can easily retrieve data from multiple tables using powerful querying capabilities.
• Normalization: Relational databases follow normalization principles to eliminate redundancy and maintain data integrity.

Understanding the concepts of relational databases, tables, and relationships is essential for working with these powerful data storage systems.
