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.

Abstract: A system, method, means, and/or computer program code may be provided to facilitate a presentation of business information to a user. According to some embodiments, a request from a client is received at a server, and the request is associated with a query. The server also receives notifications associated with business information and may block a connection with the client and/or a response to the request based on a determination that the business information does not currently satisfy a condition associated with the query (e.g., no such notification has been received). The server may subsequently determine the business information has changed and now satisfies the condition (e.g., when a notification is received). In this case, the server may unblock the connection and transmit a response, including new resulting data associated with the query, to the client.
