Have you read the "Zope Developper Guide"?

It is something like a basic guide to product development in Zope 2.

"Products" are extensions that try to have very few dependancies.
Therefore, they try not to tie other things together but use
only services of Zope (which is always available).

The things that tie together are Zope itself and larger frameworks
on top of it, such as e.g. the CMF or Plone/CPS/Silva.

Look for the product "PAS" (PluggableAuthenticationService).

There is a product "TinyTables" (or similar) for (as the name tells you)
"tiny" tables.

Zope does not (yet) support large tables (it is not a relational database).
But, you can use the "ZCatalog" to search your objects.
Read the "searching" chapter in the Zope Book (Online, 2.7 edition).

There is no difference in attribute access for persistent objects
(those in the ZODB) and standard Python objects.

Read the Python tutorial.

>collecting a variable in one page and passing it on to another page

You have the standard HTML facility (e.g. query string and hidden variables;
function in "ZTUtils.Zope" help you in using them) and
you have sessions (explained in the Zope Book; read it!)

I guess, you read the resources mentioned above ("Zope Developper Guide"
and "Zope Book, 2.7 edition, online") and then come back with concrete

Maybe, you then write the tutorial you are looking for now -- to
the profit of future new Zope users...
