No. hehe. This stuff is confusing because the language they use isn't meant for programmers, it's meant for non-programmers. When you hear them use all the fancy descriptions, you think "there's got to be more to it", but there actually isn't, hehe.
In your example, CEP/ESP would be someAnalysis, and would provide an interface in query format to access the class.
You're a programmer and probably do your own development, so CEP/ESP is worthless. Just like it is for me, because that's what I do too.
But, someone who has no idea how to deal with socket messages or create a someAnalysis class would probably find CEP/ESP a good tool. Or, a developer might want to use it to provide an SQL-like interface for his clients or company to use without that client needing to know c++. The only other reason I can think of is if a big fund or bank wanted to implement something like this, but after cost-analysis realized it would be cheaper to just purchase a canned solution.
