Today, system designs and their management are crucial parts of most systems development processes. To stay competitive engineers from several expertise domains use Model-Based engineering (MBE) to design the systems they intend to implement in order to specify, test, simulate, validate and iterate their design as soon as possible. System designs are living(More)
Managing models requires extracting information from them and modifying them, and this is performed through queries. Queries can be executed at the model or at the persistence-level. Both are complementary but while model-level queries are closer to modelling engineers, persistence-level queries are specific to the persistence technology and leverage its(More)
Persisting and managing models larger than a few tens of megabytes using XMI introduces a significant time and memory footprint overhead to MDE workflows. Several approaches provide alternative persistence mechanisms based on databases that can be integrated with EMF. However, to the best of our knowledge there is less coverage of approaches on models(More)
