JD Edwards One World Java and PHP
JD Edwards One World is arcane and antiquated. It is essentially based on 1980's technology.
Have you ever had to debug one of their proprietary C+ application modules? It's not a lot of fun. Plus, OW is buggy. It will bring down a system without constant monitoring and maintenance.
Sure, there are a lot of features but then you have to consider the high support costs. Also, Oracle is phasing out the product for their cloud service. HELLO, CIO's, there is still time to get out, switch to Java or PHP, internal programming and get some QA people in there to check on the programmers. Don't talk to me about project managers. My experience? Useless. We want a SCRUM manager. No you don't.
JD Edwards World (not One World) is RPG driven and only runs on IBM systems. It also has this weird security system. At one place, we just allowed full access to everybody. We wrote our own security functions for certain applications.
I'm a PHP guy. I can streamline everything if anyone is hiring.
In-house programming... still the way to go. It is cheaper in the long-run.
