Description:

In section 31.1 it says "A publication is a set of changes generated f= rom a
table or a group of tables"... that seems wrong. It's a set of rel= ations,
tables, whatevers. No the changes themselves. Right?

It's correct.=C2=A0 The subscriber rec= eives ongoing "events" which are the logical changes to all table= s defined within the publication.=C2=A0 The items of interest are the ongoi= ng changes, the list of tables is just a table of contents for which change= sets are present.
