Query miner Class

Can someone Explain me the use of Query miner Class

Thanks in Advance

Why do you consider using it? What are you trying to achieve?

Not in the Scenario. I want to know what is the use of query miner and why they introduced in Ax 2012. I saw in system classes

Because Microsoft needed it for some system logic, I guess.
If you don’t need it for anything, just don’t worry about it and use your time for something more productive.

Thanks for reply

This a good question. With respect to Martin, I don’t like his answer. It’s good to know what things do. QueryMiner might do something I’d find useful, but if I don’t know what it does, I’ll never know if it will be of use to me. If someone does know what it does, I’d appreciate knowing.
