Distributed system consist from from RaspberryPi workers. These workers are building up GraphDatabse (Neo4j) based on simple logic of exchanging cars. The result of the exchanges is send to the BASE server and projected into GraphDatabase. Server uses Spring Framework 4.x and each RaspberryPi worker Netty 4.x
