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)
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)
Persisting and querying models larger than a few tens of megabytes using XML introduces a significant time and memory footprint overhead to MDD workflows. In this paper, we present an approach that attempts to address this issue using an embedded relational database as an alternative persistence layer for EMF models, and runtime translation of OCL-like(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)
Model-based software development promises improvements in terms of quality and cost by raising the abstraction level of the development from code to models, but also requires mature techniques and tools. Although Eclipse Modelling Framework (EMF) introduces a default persistence mechanism for models, namely XMI, its usage is often limited as model size(More)
Cloud service-based applications are to be adapted to serve multiple platforms and stakeholders. Atop of such services, Smart Green Buildings are fostering a plethora of processes within their sustainability life-cycle. This introduces a number of challenges, as how to support multiple perspectives of domain-specific variability and how to deal with large(More)
