PostgreSQL
- Cost: Completely free and open source, offering economic flexibility without costs tied to usage.
- Flexibility: Highly adaptable for a range of environments, from small applications to large enterprise systems.
- Intuitive Interface: PostgreSQL offers a variety of intuitive graphical management tools, such as pgAdmin, one of the most popular interfaces for managing PostgreSQL databases.
- Fewer Restrictions: Compared to commercial systems, PostgreSQL imposes fewer constraints, allowing for scalability without additional costs, unlike solutions like Oracle or SQL Server, which have more restrictive licensing.
