Using NEO4J database and graph model for analysis of metropolitan railway connections of Silesian voivodeship in Poland

The study concerns the possibility of using the Neo4j database as a graph analysis tool. The analysis was presented on the example of the railway connection network assessment when designing a new version of the railway infrastructure in the Silesian Voivodeship. The authors present the concepts of a laboratory environment built on the basis of the Neo4j database, and an application that allows obtaining data and modifying the railway infrastructure model. Thanks to this, it is possible to simulate many variants of the designed model and its evaluation using the proposed measurement indicators. The study presents methods and tools of analysis that can be successfully used to assess the topology of a graph in many different research areas, such as analysis of management systems, computer networks or biological systems
