Database is the backbone of almost every modern application, enabling structured storage, retrieval, and management of data. Whether it’s a simple website or an enterprise-grade system, databases play a critical role in ensuring data integrity, availability, and scalability. Understanding database fundamentals is crucial for a variety of IT roles including backend developers, data analysts, system architects, and DBAs (Database Administrators).

This category focuses on key database concepts like relational and non-relational databases, data models, normalization, SQL queries, indexing, transactions, and ACID properties. It also covers real-time use of major database systems like MySQL, Oracle, SQL Server, PostgreSQL, and NoSQL solutions like MongoDB and Cassandra.

In interviews, candidates are often tested on query optimization, joins, subqueries, stored procedures, data security, and performance tuning techniques. With the rise of data-driven decision-making, even non-developers are expected to understand basic SQL and database reporting tools.
