Good morning, I develop web applications for enterprise, my enterprise uses Microsoft SQL Server Express 2008 R2 version, do I need to purchase a license? And if I have 3 clients connecting to this web application, do I have to buy a CAL license for these 3 clients? Thank you.

    SQL Server 2008 R2 is very old and out-of-support since a very long time; you should switch to a current version.

    Yes, you can use Express Edition for free, also for commercial is, see
