PHD in Datawarehousing and Business Intelligence

Dear Friends,
I would like to pursue Phd in DWH and BI. i am DWH developer.
I have come across so many books and net. I didnt find what we can implement into DWH and BI? or what is the best things to do enhancement in DWH and BI?

Because, now lots of features introduced in all ETL tools and BI tools.

Kindly suggest, if you have any idea.

Yes, that is what makes it so complicated. Well, to be honest, you are probably more qualified than I am to make such a recommendation, because this is not my field. Please provide the names of a few relevant articles you have recently read about this subject -- and make sure the articles are no more than 2 years old.

If you do that, I may be able to help you. Always look in the introductions of your articles to see what they say about other recent work that has been done. That is how to determine the best things to do as a scholar for the enhancement of the field.

:-)

Thanks for you reply.

whatever I have come across article will not help to start my proposal.
If anyone have good article, pls share.
