The overall structure of the SASE+ language is: PATTERN < pattern structure > [WHERE < pattern matching condition >] [WITHIN < sliding window >] [ENDS AT] < attribute with temporalAggregate (and Group) operator
for aggregations in combination with sliding windows is how to handle events which leave a window (they become invalid). A simple approach is to keep every event … the concept of online aggregations. In this concept, only the minimal needed information is kept to calculate an aggregation over a window by utilizing so calledODYSSEUS_HOME
