问题:

Where can i read more about Rails 3.2's Data Store feature, in which there's the option to store key-value in a textfield mentioned here:

Is there a best practices/coherent way to update a database field that contains a hash key-value store?

This is a seperate question because i was not able to comment on previous question.
