Searching in big databases is the need of the hour. With ever growing applications and customer base, quicker search over the data helps you survive. Modeling Frameworks sit at the core of modern software. The increasing complexity of business requirements are reflected in the increasing complexity of the modeling framework. What if you could query the complex models within seconds? This is just one use case of VIATRA Query.

VIATRA Query is an Eclipse project. Initially conceived by the Budapest University of Technology and Economics, VIATRA is an Event-driven and Reactive Model Transformation Platform.  We have used VIATRA Query to create a small search engine for Ecore models of EMF using Natural Language Based Rule Engine and would like to share our experience with it.

VIATRA Query enables the user to query the EMF models without having to manually traverse them. Complex queries can be converted into patterns. Parameters to models can be passed at runtime, something which is crucial to any query engine. The idea of creating a search engine using VIATRA Query opens up new and innovative ideas of working with Eclipse Modeling Framework.
