I have a proposal out to use CGI COBOL in our shop. I don't think it's
going to be accepted.
We've been running our corporate web site on ASP.NET (and accessing the
iSeries as needed) for over 12 years now. We also have a number of custom,
in-house web sites written with ASP.NET and accessing the iSeries as
needed. The question is what are we going to use to start developing web
and mobile applications instead of 5250 green screens.
The question I'm being asked is why would we want to have two ways of
developing web and mobile applications? That means we will have to maintain
two sets of legacy applications and maintain sufficient staff with the
right skills. Add that to the demonstrated success over more than a decade
at using the ASP.NET approach. So why in the world would we want to add
COBOL CGI to the mix? That's the obstacle I have to overcome to sell a CGI
COBOL approach, or an IBM i Integrated Web Services approach, or any
approach other than ASP.NET.
Our development teams are organized by lines of business. So the browser
UI and SPA developers on the client side, and the ASP.NET web application
and services developers on the server side, will actually be on the same
team. The team is responsible for end-to-end application development for
their lines of business. So pointing fingers at each other gets us nowhere.
I think that will be a non-issue for us.
Thanks,
Kelly

SO, when something does not work as expected, or fais, you can bounce
blame betwenn two teams.
I think Nathan sugested using Cobol, this will be by far the best
alternative.
More reliable, less downtime, less cost, scalable, easier to develop,
easier to debug, faster, better security...

And, instead of having individual COBOL developers create end-to-end
coding browser UIs and SPAs on the client side, and (b) coding traditional
web applications and RESTful services on the server side. So, in terms of
web and mobile development, some of COBOL developers would become
client-side developers and some would become server-side developers (on
windows servers). It's a different approach for us than individual
developers creating the 5250 green screens and the business logic behind
them.
suggesting that one approach was safer or better than the other; just that

The model gets exchanged between the client and the server, and the

I understand that, because browser page (UI) generation is being moved

Our data grid component can do page by page loading, filtering,
sorting on huge files just as easily as a green screen subfile can.
That's good, but it doesn't sound like 2-way binding. Or is it?
