An overview of graph databases and their applications in the biomedical domain

Santiago Timón-Reina, Mariano Rincón, Rafael Martínez-Tomás
2021 Database: The Journal of Biological Databases and Curation  
In this work, we survey the literature to explore the evolution, performance and how the most recent graph database solutions are applied in the biomedical domain, compiling a great variety of use cases  ...  From early graph models to more recent native graph databases, the landscape of implementations has evolved to cover enterprise-ready requirements.  ...  In this case, the modeling strategy follows a protein-centric approach without a rigid schema or upper model (such as an ontology).  ...
