Datalog is a derivative of Prolog, and LogicBlox (who employ Terry and Matt, NORMA's authors) has their own version of it.
NORMA Pro is not yet available, I'm sorry. I have a development version only because I'm corresponding with Matt as I build my own ORM-derived modeling language, the Constellation Query Language (CQL). NORMA ...
What is DataLog, is it specific to Norma Expert tool? Thx
That is outstanding. I would definitely like to get my hands on the professional version and try it out. The queries and proper verbalization and documentation of those queries is what I find most useful in a production environment. I wish the Norma tool had better support for derived fact types to be code ...
NORMA Pro has derived fact types, which are the ORM equivalent of SQL's views (both are essentially just objectified queries). I'm not sure how complete the mapping is to SQL queries/views though. The mapping to Datalog is the first and most complete generation target. Also, the user interface for creating derived fact types... leaves a ...

Please will you tell us a bit more about your requirements for "Queries".

Is it possible to create only queries in Norma? If not I think it would be a good future candidate for adding to the tool. The reason I'm asking is because I think that Norma is a perfect tool for describing queries and it puts a report, form, or business rules into manageable chunks that can be referred ...
Hume and Kant made important contributions to philosophy. However, their contributions predated the computer era.
If you don't want to accept the evidence of Graham Simpsion's PhD thesis (reported in his book "Data Modeling: Theory and Practice) then I suggest that you (and your students) study William Kent's book ...
In response to Clifford, in great haste because I'm about to be away and out of communication until next Tuesday:
(a) At the physical layer anything goes. If some kind of "sparse matrix" gives desired performance while a more direct representation of the logical schema doesn't, then go for it. (I have often made this ...
