In addition to that, I've started to write a JavaScript library for the Slicer server (not mentioned in the blog post). I am just starting with JS, so pardon my style. The sources can be found here: https://github.com/Stiivi/cubes.js https://github.com/Stiivi/cubes.js No examples yet, however the goal is to be able to browse aggregated data directly from JS and transform them into tables/charts. Concerning backends: I have not much time to write other backends, however, if anyone is interested in helping me with them, just drop me a line. I would like to have at least nicer star-schema browser and perhaps the mongo DB backend.

Very nice. I did a day project a while ago to do something basic. http://www.binarymax.com/cube.html http://www.binarymax.com/cube.html (NOTE: doesnt work in firefox, but is fine in all other browsers). I'm pretty sure my algorithms would quickly run into stack and memory issues quite quickly, but I havent looked at it in 6 months. How long have you been studying OLAP structures and algorithms? Its the kind of stuff that is very interesting, but I sometimes have trouble wrapping my head around. I'm curious if you have any favorite reading materials on the subject? EDIT: also FYI, your link on the blog to the github js repo goes 404 since it has an extra '.' on the end

  For a good description of OLAP data structures and algorithms, I'm a fan of _Data Mining_ by Jiawei Han and Micheline Kamber

  Thank you. How long? I was working for around 5 years in (later with) a data warehouse in a mobile telco company, now I am doing "data brewing" as a freelancer. My favourite book is Star Schema The Complete Reference by Christopher Adamson. Very very brief introduction to OLAP and Cubes you can see in my slide deck: http://www.slideshare.net/Stiivi/cubes-7781602 http://www.slideshare.net/Stiivi/cubes-7781602 Thanks, fixed the link.

A similar project is Saiku ( http://saikuanalytics.com/ http://saikuanalytics.com/ ), for the front-end they use saiku-ui. https://github.com/OSBI/saiku-ui https://github.com/OSBI/saiku-ui It's one of the most popular niche-sounding areas to be in right now.
