At word "CORBA" the hair on my back lifted up. I hated that one with every fiber of my being 20 years ago when, on a job, I had to deal with it. I avoid it like plague after leaving there and I am so glad is a forgotten technology none uses anymore (maybe except some legacy projects, God have mercy on poor souls that have to do maintenance on those projects).
Ugh I had to do some work for the COBRA subsidy during COVID and to give you and idea how horrid this was, the frontend was an Access DB sourcing data from SAP.
