Abstract
A system, method, means, and/or computer program code may be provided to facilitate query creation and a presentation of information to a user. According to some embodiments, continuous query definition parameters are received from a user via a graphical user interface. Moreover, semantic layer information associated with an event processing engine may be retrieved, the event processing engine being adapted to receive an event stream. Based on the continuous query definition parameters, a pre-fetch query may be automatically created to pre-fetch historical data from a database. An event processing language statement may also be created based on (i) the continuous query definition parameters and (ii) the semantic layer information. The event processing language statement may be provided to the complex event processing engine so as to establish a continuous query. A response to the query may be output based on both the pre-fetched historical data and events in the event stream.
