Abstract

A system, method, means, and/or computer program code may be provided to facilitate a presentation of information to a user. According to some embodiments, continuous query definition parameters are created by a user via a graphical user interface. Moreover, semantic layer information associated with an event processing engine may be provided. The event processing engine may, for example, receive an event stream from a data source. According to some embodiments, the semantic layer information is defined by a semantic layer designer via a graphical user interface. At least one event processing language statement may be created based on (i) the continuous query definition parameters and (ii) the semantic layer information. The statement may then be provided to the event processing engine so as to establish a continuous query at the event processing engine, the continuous query providing output data based on events in the event stream. According to some embodiments, a continuous meta-query for a complex event processing engine is initially created. When a connection with a business user is subsequently established, a continuous user-query is initiated based on the continuous meta-quer…
