STAC, as cited in the popular Blog of Tim Bass, has determined that the correct name that should be used for event processing products is EPP (Event Processing Platforms) rather than CEP. I actually like the term EPP, actually I used this term before, so I should have copyrighted this name...
However, EPP should be used in the right meaning.
In event processing software there are two different things:
- Platforms that provide the "programming in the large" -- indeed a container in which different types of functionality can be plugged in.
- EPA implementation Software - that performs the actual event processing work - e.g. pattern matching, enrichment, filtering etc... This is the "programming in the small" (I called it "event processing engines", but not convinced that this is the best name)
These are not the same, there are vendors who provide platforms, but use other software to implement agents For example - BEA provided a platform, and used Esper for various functions, if I am not mistaken this is also true for Event Zero, IBM's Infosphere Streams is also a platform -- all are indeed platforms. Some products provide both the EPN platforms and various EPA implementations, some provide just the EPA implementation and runs on various platforms (or as a centralized stand alone engine).
So, while I agree that the EPN implementations are platforms, I am not sure that the EPA implementations are also platforms, and we probably may need a different name (engines ?, not sure)...
And one sentence about the term CEP. As I have written several times, I am not a big fan of this term at all, I am consistently talking about event processing and not about complex event processing as the name of the discipline that this Blog covers. However, this reminds me that once I have been a member in a Hebrew technical terminology committee, and one of the terms that came for discussion has been "real-time", for some strange reason, in Hebrew it was translated literally as "true time", and when it came to write the official glossary endorsed by the Israeli Academy of Hebrew Language, their representative who knew Hebrew linguistics, but not computer science, insisted the the Hebrew word should be a true translation of "real time", giving a long talk about "real numbers" and other real stuff. I argued that --- from linguistic point of view he is probably right, but, the scientifically wrong name is already well-known in the industry, and decision on another name would not be accepted by the public. After long discussion he agreed to include my wrong version as an alias to his true version. You can guess which of the two is still being used for "real-time" in Hebrew.
The moral of this story is that it may be too late to change names, since the name CEP has been accepted in the industry for any type of event processing system, whether or not it is scientifically accurate, and as somebody said once -- resistance is futile...
I'll continue to use "event processing", will use "event processing platform" for a platform, and still looking for a term for the "EPA implementation" (engines or otherwise). But -- my guess is that the people that use CEP to denote any type of EP will continue doing it, since this name may already penetrated to the ground. More - Later.
