PostgreSQL example of self-contained stored procedures

First, see my previous article about PostgreSQL functions at sive.rs/pg. That article gave tiny examples, but no finished working code.

This week, I wrote a shopping cart to sell my books directly from my own site.

So I took a couple extra hours today to put my code into public view, so anyone can play around with it. See github.com/sivers/store, to browse, download, and try it.

It’s a working self-contained shopping cart / store. It’s a very concrete example of using stored procedures to keep all the data logic together in one place. You can use it from JavaScript, Python, Ruby, or any language you want, since all the functionality is in the database itself. It works.

If you have any questions, or want to tell me how stupid I am for doing this, email me.
