Software Architecture Exploration and Validation with jqAssistant, Neo4j and Cypher

Sunday, December 31st, 2017

I have written about other software system analyzing and validation tools before but today I would like to introduce a new tool named jqAssistant that supports software architects, developers and analysts in a variety of tasks like analyzing given structures, validating architectural or quality constraints and generating reports.

Therefore jqAssistant analyzes given projects or artifacts and stores the gathered information – that is enriched by a variety of existing plugin-ins – in a Neo4j graph database.

This graph database may now be used to enforce architectural constraints or specific code metrics, to generate reports or to analyze a system with a nice browser interface.

In this tutorial I’m going to show how to integrate jqAssistant in an existing project using Maven as build-tool, how to explore an existing system step-by-step and finally how to enforce specific metrics by writing them down as a kind of living documentation in an AsciiDoc document.

I have also started to write down basic Cypher (the query language used) queries to analyze a system and other queries to gather basic metrics.
