I've become a big fan of datalog and souffle. We wrote a territory assignment application for a large healthcare organization with multiple overlapping marketing teams, where each team defines territories with various geographic and account attributes such that there's a hierarchy of precedence for the territory that should be assigned to each account.

The datalog application that replaced an existing imperative solution is so much easier to understand and maintain.

Souffle generates c++ from the datalog program. We use SWIG to compile the c++ code into a Go application. So we have a Go application that deals with getting data in and out, and all of the business logic is defined in datalog.

this is a pretty interesting workflow. I was indeed thinking how one would integrate Souffle into a bigger application.

Here's a simple example: https://github.com/cwarden/souffle-go-example

It illustrates how you can have the Souffle program load its data from SQLite databases, or how you can work with tuples and relations from Go.
