Abstract: A Query-Driven Simulation (QDS) system Cassandra + is described that allows end-users to ask temporal queries about outcomes of running simulation models written in various simulation languages. The architecture of Cassandra + , its query language SimQL, and the implementation of the system are described. It is argued that Cassandra + provides a more effective information systems (IS) support for simulations than the more traditional approaches by letting the users ask questions of interest about simulation outcomes in a declarative, flexible, and interactive fashion. To demonstrate the usefulness and practicality of the QDS approach and Cassandra + in particular to asking queries about simulation outcomes, we present a case study. In this case study, we show how Cassandra + performs on an "industrial-strength" manufacturing application developed by the management consulting company of Booz, Allen & Hamilton.
