COW and volume management?

> SQL may not be the prettiest language, and the relational model may not be what you want in every context - it's too abstracted when you really need to optimize for performance - but there's a reason it's taught, it's a good model, and it's something every programmer should probably know.

The relational *model* is great, yes. The engineering is flawed by design :-(

Pick allows you to stick a 4NF view directly into the database as a table row ... that's why an optimiser is a waste of time ... (now that most RDBMSs have arrays and structures, they've finally caught up, 40 years late, but SQL can't query them cleanly)
