Is PostgreSQL a front-end or back-end database technology?
The question is about PostgreSQL .
PostgreSQL is a back-end relational database management system that stores, queries, and manages structured data on the server side. It has no front-end role; it functions as the data persistence layer accessed by back-end application servers through SQL queries, ORMs such as Prisma or SQLAlchemy, or direct database drivers. As of 2026, PostgreSQL remains the most widely recommended open-source relational database for production applications, supporting advanced features such as JSON storage, full-text search, and vector similarity search via pgvector.
