Compare each version of Microsoft SQL Server.
Each edition of Microsoft SQL Server supports different performance, runtime, and pricing requirements based on your application needs. Installation depends on your specific requirements, with SQL Server Express available as a free download. But there is a maximum database size of 10GB and other limitations. That’s more than the paid version.
