Re: Business Logic Servers ( was: MVC in RPG?)

The "how to" of writing an UI agnostic business logic server from scratch is
exactly the process that I'm trying to understand. Although I've seen many
references to the use of these servers, I've not been able to find an
article, book, or CBT course that fully describes the implementation details
and the process for creating one of these servers using ILE RPG best
practices.

My original question was an attempt to derive the scope of the server. Is
there a one-to-one relationship between the server and the traditional
monolithic green-screen program or should the server be more
generic with some type of "controller" program sitting between it and the
UI?

Yes and no, Jake. While you can take an existing program and turn it into
a
server using this technique, you can also write the server program from
scratch to be UI agnostic. The nice thing about the approach in the
article
is that it provides a quick way to turn an existing monolithic program
into
an interim server, giving you an opportunity to immediately start working
on
the UI portion of the system even before you have your long-term server
architecture in place.

In any event, I'm tickled that you found that old article; it shows that
I've been saying pretty much the same thing for a decade or more now
<grin>.
