The OpenEdge Hive

Bruce Gruenbaum:
The Environment Service determines the context in which the framework is being run. This presupposes that the framework will run in many configurations. Although I am going to talk about it in the context of an OpenEdge application, this is a service that I have written for OpenEdge, Java and C#.

Thomas Mercer-Hursh:
So, from your description, I take it that this service is one per session? Does it have any inputs? Is its output something like an XML document containing a list of cans and can't or does it simply have a bunch of methods of the form "canIDoSuchAndSuch()? Do you see this as a persistent component in each session which is queried repeatedly by the application to determine whether or not it can do something or is it a startup function that passes the information on to the application and goes away? Where does it get its information? E.g., if it is running for a client session with no DB connection, is it going to connect to a DB in order to get the information? Or, do we have a local service and a provider service which is a central source for the information?
