Incquery Server For Teamwork Cloud Scalable Query Evaluation Over Collaborative Model Repositories

Large-scale cyber-physical systems are co-engineered, especially in safety-critical industries, by various specialists within an organization and, increasingly, across organizations. The collaborative aspect of the process is facilitated by hosting engineering artifacts in model repositories. In order to validate the adherence to design rules, perform change impact analysis across projects, generate reports etc., engineers specify model queries and evaluate them using query engines, traditionally available in client modeling tools.In this paper we introduce INCQUERY SERVER FOR TEAMWORK CLOUD (IQS4TWC), a standalone middleware service that connects YO TEAMWORK CLOUD model repositories, and builds on VIATRA QUERY to provide fast querying over their content. The new serverside solution provides advanced features including single-model ad-hoc queries as well as repository-wide change impact analysis (correlating projects across branches and revisions); access to version snapshots as well as queries on the latest state; and a range of performance fine-tuning options (such as elasticity and in-memory indexes) to achieve high scalability.Screencast demo: https://goo.gl/rScgco
