decrel-core

Welcome to the source code/javadoc of decrel, library for declarative programming with relations.

decrel is built on the idea to allow clear expression of relations that are implied in your domain models.

Traditionally, one way such relations are frequently expressed are in the form of SQL foreign key constraints. Other places may also include documentation living outside of the codebase as diagrams.

All of these expressions of relations are not easily usable directly in the code. Therefore, it is the programmers' job to understand these relations and translate them into imperative steps in order to express a desirable outcome.

The goal of this library is to allow expressing underused implicit knowledge as an explicit first-class value, and achieve better expressiveness in other parts of the code as a result.
