The limitation of traditional databases, in particular relational model, to cover the requirements of current applications has leaded the development of new database technologies. The graph databases are calling the attention of the database community because in trendy projects where the database is needed the extraction of worthy information relies the processing of graph-like structure of the data. In this paper, the authors present the systematic comparison of Neo4j and Dex graph database models. This paper includes general features (for data storing and querying), data modeling features (i.e. data structures, query languages and integrity constraints) and the support for graph essential queries with comparison of different graph databases such as Neo4j and Dex graph database models.
