Database
A database is an organized collection of structured data stored electronically, enabling efficient storage, retrieval, and management of information.
Why It Matters
Every application needs to store data somewhere—databases provide the reliability, speed, and query capabilities that make dynamic applications possible.
When to Use This
- Storing user accounts and profiles
- Managing product catalogs and inventory
- Recording transactions and orders
- Keeping application settings and configurations
Examples
- MySQL storing customer orders with relationships to products
- PostgreSQL with geospatial data for location features
- Redis caching frequently accessed query results
