Abstract:
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 increases. To overcome this limitation, during the last years alternative persistence mechanisms have been proposed in order to store models in RDBMS and NoSQL databases. Under this new paradigm, model operations can be performed at model-level and persistence-level, e.g., mapping EOL model operations into SQL statements. In this paper, we extend our framework (called MQT) to support CRUD (Create, Read, Update and Delete) operations from model- (EOL) to persistence-level (SQL), using a streaming execution of queries at run-time. Through comparable evaluation metrics, we evaluate the performance and memory footprint of the framework usi
