Ah, yes, you're right! Please do: # ... Q(your_column) :- example_db.YourTable(your_column:); You can query multiple columns of course. Feel free to start threads in Discussions of…

In my opinion any analytical query is easier to read in logic language than in SQL. But it's most obvious for recrusive querries. E.g. distance in graph defined by predicate (aka t…

To connect to a database file use: @AttachDatabase("db_prefix", "your_file.db"); # Then you can query from it: Q(..r) :- db_prefix.YourTable(..r);

There is a standard method of optimization - breaking predicate into smaller ones and saving intermediates into database. Typically program runs efficiently, but when optimization …

Yeah, we need better tutorials. To use SQLite use @Engine("sqlite") imperative. And you can then connect to you database file with @AttachDatabase imperative. For example if you ha…

yes.

I think of Prolog as a general purpose logic programming language and Datalog to be logic programming more focused on data analysis. Data analysis is a very large area, so boundary…

I have update Logica homepage. Hope it helps to get a sense of what the language is about.

Looks like Mangle differs from Prolog when it needs to express aggregation. I am curious what prolog dialect/library you think has good(or best?) aggregation syntax?

That's right. And btw Logica is also open source: https://github.com/evgskv/logica
