Unlearning Relational DB

Some of my first university programming was writing CICS COBOL transactions against IBM’s DB2 relational database. My commercial work after uni was mostly written in Clipper which was a sort of compiled version of dBase and used the same data file format. The minimal web work I did in the before times relied on MySQL .

All of which is to say, I’m very comfortable designing relational database schema, and I understand what’s going on at the disk level when they are being accessed and written to.
