Database Design
Database design is the process of structuring a database to efficiently store, retrieve, and manage data according to business requirements. It involves defining tables, columns, relationships, constraints, and indexes to ensure data integrity, performance, and scalability. This foundational skill is critical for creating robust applications that rely on persistent data storage.
Developers should learn database design when building any application that requires data persistence, such as e-commerce platforms, content management systems, or financial software. It's essential for optimizing query performance, preventing data anomalies, and ensuring the database can scale with application growth. Proper design reduces maintenance costs and improves application reliability.
