When it comes to choosing a database management system (DBMS) for your organization, there are several options available, each with its own strengths and weaknesses. Two popular choices are PostgreSQL and SQL Server. While both are powerful relational database systems, they differ in various aspects, including features, licensing, scalability, and community support. In this article, we'll compare PostgreSQL and SQL Server, highlighting the benefits of PostgreSQL over SQL Server in a tabular format:
