- Usually when have <tt>Active Records Classes</tt>
- there are correspondingly the proper views to handle them.
+ Usually when you use <tt>Active Records Classes</tt> to interact with your Data Base
+ you also build some proper views to handle them. To save every element of your views in your Data Base
+ you need first to assign everyone of them to their corresponding attribute in one of your AR Classes.
+ This task is really tedious and usually takes a significant amount of your time.
+ Thats why Prado offers an automatic mechanism to update your views from your AR Classes and vice versa.

- When an AR class attribute does not match any of the controls IDs on the view, nothing will happen
+ Note that the identifiers of your controls should be exactly the same of the attributes of your
