What database do you use on the backend?

Answer from AI
The choice of database on the backend depends on the project requirements, data nature, and load. In my practice, I have used different databases:
-
Relational databases (SQL): PostgreSQL, MySQL — suitable for structured data with clear relationships, support transactions, complex queries.
-
Document-oriented NoSQL: MongoDB — convenient for flexible schemas, rapid prototyping, scaling.
-
Key-value: Redis — for caching, sessions, fast operations.
-
Columnar and graph databases: in specific tasks.
For example, for REST API with user and order data, I often use PostgreSQL due to its reliability and powerful features. For caching and speeding up access — Redis. If the project requires a flexible schema or rapidly changing data — MongoDB.
The choice of database should always consider requirements for consistency, scalability, development speed, and support.
