Retrospective event processing pattern language and execution model extension

A method of event processing, said method comprising the steps of:

• providing an event processing language suitable for handling streaming event processing;
• adding retrospective pattern language extensions to said event processing language such that the resulting extended event processing language is capable of handling retrospective event processing in addition to said streaming event processing;
• and
• wherein said steps of providing and adding are implemented in either of computer hardware configured to perform said providing and adding steps, and computer software embodied in a non-transitory, tangible, computer-readable storage medium.

A computer program product for performing event processing, the computer program product comprising:

• a computer usable medium having computer usable code embodied therewith, the computer usable program code comprising:
• computer usable code configured for providing an event processing language suitable for handling streaming event processing;
• and
• computer usable code configured for adding retrospective pattern language extensions to said event processing language such that the resulting extended event processing language is capable of handling retrospective event processing in addition to said streaming event processing.

A computer program product for performing event processing, the computer program product comprising:

• a computer usable medium having computer usable code embodied therewith, the computer usable program code comprising:
• computer usable code configured for providing an event processing pattern language;
• and
