Amazingly low prices for SQL Server!
Recently did a research for a client and have found SQL Server Standard edition for only $140!!!
Yes it is true, please see SQL Server 2012 Standard Device CAL OLP/SA.
Because of that low price it has very big limitation to ONLY ONE user connecting to a server.
So, what? If you have a web server with SQL Server back end it is exactly configuration you are going to use.
