What database was used in your last project?

In my last project, a relational database PostgreSQL was used. It is well-suited for storing structured data with support for complex queries and transactions.

PostgreSQL provides reliability, scalability, and rich functionality, including support for JSON, which allows flexible handling of different data types. In the project, the database was used to store information about users, orders, and logs.

An example of a simple query in PostgreSQL:

SELECT id, username, email FROM users WHERE active = true;
