What is REST?

REST stands for Representional State Transfer and is defined on Wikipedia as:

Representational state transfer (REST) is a software architectural style consisting of a coordinated set of architectural constraints applied to components, connectors, and data elements, within a distributed hypermedia system. REST ignores the details of component implementation and protocol syntax in order to focus on the roles of components, the constraints upon their interaction with other components, and their interpretation of significant data elements.

I think the second part of that explanation sounds like it could be quite interesting... but to me that all seems super complicated! So I've decided to try to simplify it for my own understanding. (If I have not understood something in this gist, please TELL ME!)

##Saving & Retrieving information For this section, think of a web application as a piece of software built to help people to store and access information online.

Generating Migrations

Migrations are a feature of Active Record that allows you to evolve your database schema over time. Rather than write schema modifications in pure SQL, migrations allow you to use an easy Ruby DSL to describe changes to your tables.

Another way of thinking about them is like a kind of version control (like git) for your application's database - only not as cool as Git (because Git rules).

##Each database starts empty Every database starts empty. Adding information to a database can be described as a series of steps, one after another... Migrations allow developers to save the most important steps like creating tables or adding columns. Later you can rollback to before these changes if something goes wrong, although you might lose data if you do this!
