MySQL, widely accessible for free, is often chosen by startups and web developers, while MSSQL caters to enterprises relying on Windows-centric infrastructure. So, the choice between MySQL and MSSQL depends on specific project requirements, budget constraints, and ecosystem compatibility.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:
