Zoho creator Sandbox and making updates to a live system.

Zoho creator Sandbox and making updates to a live system.

I'm finding the help file on sandbox too simplistic to help me make some major design changes to an app i have been working on.
It states that "
  • Changes in Form Definition and View Definition cannot be made in Sandbox mode."
However, there is no explanation as to what is meant by Form definition or View definition.
I am still new to Zoho Creator and would like to know exactly what this means before I start using the Sandbox and finding out the hard way that some of my changes have not been implemented.

If the sandbox is not the best way to do this, can someone provide me with a more practical suggestion.
