I'm concerned about concurrency and integrity issues. For example, what happens if one client alters the knowledge base while another client is using an enumerator?

This depends on the server specifications. OKBC does not specify the concurrency control issues. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
