What is Microsoft SQL?

Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications.

Microsoft SQL is one of the worlds largest used SQL Database Engines. While it can be used for the smallest of sites it is most widely known for being used for bigger type businesses and corporations as it is trusted by users globally for security, replication, integration services, and much more…

I recommend that you review the features and capabilities of SQL Server if you’re interested for more information.

What is the difference between the available versions?

Microsoft offers many different versions of it’s software, which these versions determine what features is available to the user(s). For example some versions of SQL may not let you utilize all the available CPU Cores on the server, while another (higher) version of SQL allows you to utilize all the available cores for better performance capabilities.

The comparison of the different versions vary based on the server version that you choose (such as SQL 2022, which is the latest SQL version at this time). You can find the comparison of version of SQL below:
