That rather depends on what you mean by 'only one kind of information'. In
the absence of that information, my best guess is that probably creating a
new, empty database and copying the objects you want from the old one might
be the easiest route. Be sure to click the 'Options' button on the Import
Objects dialog box - one of the options is to import tables including the
data stored in the tables, or just the structure of the tables without the
data.
