Hi, Built my first graph on a relational database about 10 years ago which was used for tracking and managing business process. In another role I extended this to include properties by hanging attributes off the relationships similar to the property graph model in idea anyway. I tried for many years to tinker with the model to manage process within process at any number of levels above the 3 in that model, but using relational databases and SQL, this just gets too complex to be achievable. Discovered Neo4j a few years ago and knew immediately that it was the tool to use for this. I see the integration and coordination of process and state achievable to achieve both squeaky clean data and clean code. Currently refining the process model as well as playing around with geographic data. Love Neo4j!
