Is cataloge an object which represents the zodb (data.fs) file? How can I
access this in catalog ZMI?

>Is there one Catalog for Employees, one for Students, etc.?

    Unless I know what catalog is, I can't answer this question?

>def extract_employees(self):

example path?

>e_id = employee.id

How do you know that there was id attribute?

OK I put that external method in root folder then? What external method
should look like? Like that example above?

I think you will eventually solve my problem. I still have 2-3 days.
