True. It was an incredibly powerful model, but developers like files they can see. I mentioned in my earlier comment a "hand-drawn diagram of the architecture" - it was in fact a picture of the exact layout of this database including all the pointer blocks etc between the classes, methods, versions, etc. One project I did was to convert that file format & pointer model to support larger database sizes of 16GB (IIRC). Fun exploring and updating that code. For testing I built a massive fake DB with random classes, methods, etc. The crazy thing was when that fake repo zipped down to almost nothing because it had so much repetition in the names!
