Agile database views

Hi,

In our Agile database, we have lots of views. Some of which we know we have created for other teams to use for pulling data from agile database, but there are a lot of views that we are not sure what are they used for.

My question is: Are there views in there that come with Agile database install, in other words, does Agile application itself uses some of those views. if that's the case, then how would I be able to know what views are being used by Agile.

thanks in Advance.
