You need to know how they envisage this working Debbie.

Is the customer going to sit down at a screen and interact with the system much as they would with 5250 but via a web page/mobile app/whatever? In which case you are building a web site.

Or - Is the customer going to interact _programmatically_ to request and update data? In this case you need to hosting a web service which they will interact with.

While there are similarities between the two, without knowing which you are being asked to provide it is tough to make any real recommendations. In other words are you being take with building a web site or a web service?

I am an RPG/Cobol programmer on the ISeries. I know nothing about interfacing with the web.
I am a newbie. We here are looking to have a web application where we will pass customer
data from the ISeries, allow the customer to make changes, receive that data back to the ISeries
and updata our ISeries data file with the changes.

I was assigned the task of researching what it would take to do this particularly using JSON. What
I am looking for at this point is not specifics. I am looking for learning materials. A good JSON
book that someone could recommend that I could use as a reference. Maybe some good
reference material of how JSon is used in an RPGLE program (an IBM reference manual maybe).

Perhaps a basic explanation as to the best way to accomplish it. IE: what happens between the
web application and the ISeries. SQL? Something else?

I'm just researching because I am very green at this point.
