How can I get maximum use from my iPhone? [more inside]
I want to write a web application. What would be useful to you? [more inside]
Can someone please help me understand how a database for a site like 43 Things (www.43things.com) works? There are users, tags for categories, user comments (for categories), and comments that can be associated with other comments. I understand that you would need a user table, a comments table, and a tags table but how do you create a schema for a site like this that works effectively? What kind of table structure is needed and how do the tables interrelate?
