Learn to create a quick, clean, clear and complete module that includes several links to several pages and most importantly, all CRUD -> Create, Read, Update and Delete database operations.
So after months of head banging, going to every forum and getting vague answers, or no answers at all, I finally got the process figured out and became a decent, in my opinion anyway, Drupal programmer.
I decided to take my notes and put them into an short eBook on just the simple, complete process of writing/coding a real, "non-block", module that shows you how to code all of the database related steps.
