Ad-Hoc Olap Query Tool

I am seeking a web-based ad-hoc query tool that allows me to connect to any database or dataset. The tool must have a drag and drop interface for performing the analysis. I am looking for something similar to OLAP cubes. The bidder must show me examples of previous work like the tool that I describe above. The tool must be well documented and contain an easy to understand user manual. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform The tool needs to run on an Apache or IIS webserver. I would prefer something built in PHP, but I will take something in ASP.Net.
