Answer 1

well , try to make the database first.

like put them in a listing , only to list your items on database (inserting , updating , deleting).
as you goes on "trial and error" , you might already learn how to manipulate them to goes online.

simple logic :
in your store you have :
3 dog foods , 5 dog cages.
save those on your table.

when you know how to update or delete (changing value of saved thing like in notepad) , go on for further simulation logic.

when dog food purchased :
reduce dog food value in database , and do something else you need to save in database(counting income perharps).

when all set , make it online as BETA (only you and several of your team know) , if it works , test your own secure-ness of it.

if it secure enough , publish.
