GT.M is a very flexible engine that allows for NoSQL operations, but also is fast in cacheing disk to memory, as well as extensive enterprise level support.

I suggest you read the discussion by Rob Tweed at http://www.mgateway.com/docs/universalNoSQL.pdf which would probably help you understand capability without jargon.
