The evaluation categories of the OSSpal methodology are focused on software functionalities, attributes and features, available documentation, support and service, user community, and graph database development.KeywordsGraph databasesNoSQL databasesOSSpal methodologyOpen source toolsJanusGraphNeo4jTigerGraph We apply the OSSpal methodology, which consists of an evaluation based on qualitative and quantitative measures to these databases. According to DB-Engines Ranking, the top three graph databases are: JanusGraph, Neo4j, and TigerGraph. The main objective of this paper is to find out which of the top three open source graph databases are the most complete and efficient. Graph databases emerged as the solution, wherein entities from the domain of interest are represented by nodes and relationships between them by edges. Therefore, it becomes difficult to store and process massive volumes of data and data where the schema is represented by graphs, such as social networking sites. Over time, data growth across technology platforms has become a challenge for relational databases. Also, by applying this hybrid approach to the evaluation of data modelling tools, we show it can robustly handle the bias from lesser relevant evaluation categories. In this work, we show that this new methodology can be tailored to the needs of each individual developer or team, thus providing proper and meaningful results. We propose a new approach for software tools’ evaluation based on the Business Readiness Rating (BRR) model and the OSSpal evaluation methodology. But it is challenging to decide how to compare them and which elements are crucial. We evaluate free and commercial data modeling tools. We recognize several types of data models, but we only include the relational data model. The primary goal of our work is to compare tools that can create this physical model. Thus, accurately specifying the physical data model is essential. The quality of the data analysis system will limit the excellence of any decision-making process. Conceptual modeling describes the physical or social aspects of the world abstractly, encompassing the interpretation of data production, gathering, visualization, and analysis.
