Interesting, yes. If you had asked what DBCC originally stood for, the answer would be different from what it stands for now.

Even on this site it was once referred to as Consistency Checker. I took Sybase internals classes many years ago, System 10 and System 11. Also worked with MS SQL Server since it was released on OS/2. So I was pretty sure of my answer but I am more of a database developer now than a DBA, so I hadn't had much opportunity (nor permissions) to use it anymore and was not aware of the re-definition.
