NeoEMF: a Multi-database Model Persistence Framework for Very Large Models

International audienceThe growing use of Model Driven Engineering (MDE) techniques inindustry has emphasized scalability of existing model persistence solutions asa major issue. Specifically, there is a need to store, query, and transform verylarge models in an efficient way. Several persistence solutions based on relationaland NoSQL databases have been proposed to achieve scalability. However, existingsolutions often rely on a single data store, which suits a specific modelingactivity, but may not be optimized for other use cases. In this article we presentNEOEMF, a multi-database model persistence framework able to store very largemodels in key-value stores, graph databases, and wide column databases. We introduceNEOEMF core features, and present the different data stores and theirapplications. NEOEMF is open source and available online
