It's the beginning of another course at the University of Texas, and i'm bringing the content direct to you. In this post of Databases & Rails: Week 1 Introduction you'll learn how the web works, how data stores are used to power the web, then we'll design a simple data store and see it implemented in PostgreSQL. Tell your friends, it's gonna be fun.
