GRAPHED: A Graph Description Diagram for Graph Databases

Graph database systems have become very popular and have been used mainly when the relationship between the data is significant, such as social networks. Although they do not require a particular schema design, a data model contributes to its consistency. An approach to satisfy this demand for a conceptual data model is the design of diagrams. Researchers and companies have been developing concepts and notations for graph database modelling, but generally, these notations are focused on own implementations. In this paper, we propose an alternative to fill the lack of a generic and comprehensive notation for graph database modelling, called GRAPHED (Graph Description Diagram for Graph Databases). We verified the effectiveness and compatibility of GRAPHED concerning the type of problem dealt with and in the database technology used in a case study in fraud identification in the Brazilian government.
