Data warehousing-related contributions

[rlaemmel]

It looks like Yves Dupont will be looking into it.

We would like to get some coverage for data warehousing / business intelligence-related technologies.

Here is what's needed:

• Some initial investigation of available (open-source) technologies in this context.
• Some sort of comparison / feature analysis of those technologies specifically.
• A corresponding review of 101companies feature model.
• A corresponding proposal for some features, if any, to be added or enhanced for 101companies.
• A small set of implementations that exercise some selected technologies.

This should really be just a first step. Thus, any sort of completeness is not expected.

The set of contributions should be developed in a designated github repo. See here for the recipe:
