[ic] NoImport Directive in catalog.cfg

[Houman Akhavan]

I plan on enabling the NoImport directive in catalog.cfg because I am using
an SQL db (mysql).

Quoting the online docs:

NoImport
"When set to one or more Interchange database identifiers, those database(s)
will never be subject to import. Useful for SQL databases, or databases that
will *never* change."

Does this mean the import feature in the administrative interface will be
disabled?
Also is this directive the equivalent of having table_name.sql files in the
products directory?

Thanks,
