Electronic Data Interchange
When I began working at TST Water I had no idea that EDI even existed, let alone what it was. It wasn't in the job description. The previous developer had built an internal website in VBSCRIPT called EDI and I figured that part of my task might be to update the website to maybe a more modern version. I was wrong EDI is sort of an old markup language or document model that is sent and retrieved from computer to computer basically over an email protocol network.
The file is sent via email and another computer reads and parses the data and in turn creates a response.
