It is an alternative to Active Record (which is a part of Rails).

One difference between Og and AR is that Og handles the messy parts of 
the persistence layer  It writes the SQL  for you (if the persistence 
layer uses SQL;  I believe there are, or will be, file system and 
Kirbybase bindings).

What I like about this is I can write and evolve my application with a 
focus on objects and behavior, without thinking of what database, if 
any, I might be using, or what tables, if any, I might need to create. 
As I go along, I can easily add persistence to objects by adding a few 
lines of code to the class def.

It helps avoid a lot of big upfront design.
