Do you know which database management system is used by your company’s servers? Obviously your end users aren’t expected to know the answer to this question, but this is something that you, as a business owner, need to be aware of. If you don’t keep track of which database software you’re using, you might accidentally wait too long and wind up running an unsupported piece of software. For example, you need to move away from SQL Server 2005 (which is now unsupported) as soon as possible.
