I can’t emphasize the importance of rule-5 enough.

I learnt about rule-5 through experience before I had heard it was a rule.

I used to do tech due diligence for acquisition of companies. I had a very short time, about a day. I hit upon a great time saver idea of asking them to show their DB schema and explain it. It turned out to be surprisingly effective. Once I understood the scheme most of the architecture explained itself.

Now I apply the same principle while designing a system.

Yes, fully agree. Rule 5 has been the center of my approach to designing and writing software for over 30 years now. Fad methodologies and platforms come and go but Rule 5 works as well for me today as it did in 1995.

I can't agree more. I live and breath by rule #5.

Getting competent at it, however, is no joke and takes time.
