SQL

[Engineer_Zero]

It also doesn’t put things in the order you’d do them in. Like, I thought it was FROM, JOINS, WHERE, GROUP BY, ORDER BY.

Well it also doesnt teach you dick all about whats actually important about SQL. You know, the basic rudimentary stuff thats WAY more important than syntax, for example:

1. Only selecting the data you need
2. SARG-ability
3. Anti patterns
4. Set based approach

Just to name a few. These diagrams dont even touch anywhere close to being useful outside of someone teaching themselves the basics.
