Can you point to sources? 4.3 only requires attribution for produced 
works. 4.5 explicitly says that you don't need to share your collective 
database.

4.3 Notice for using output (Contents). Creating and Using a Produced 
Work does not require the notice in Section 4.2. However, if you 
Publicly Use a Produced Work, You must include a notice associated with 
the Produced Work reasonably calculated to make any Person that uses, 
views, accesses, interacts with, or is otherwise exposed to the Produced 
Work aware that Content was obtained from the Database, Derivative 
Database, or the Database as part of a Collective Database, and that it 
is available under this License.

       a. Example notice. The following text will satisfy notice under 
Section 4.3:

     Contains information from DATABASE NAME, which is made available
     here under the Open Database License (ODbL).

4.5 Limits of Share Alike. The requirements of Section 4.4 do not apply 
in the following:

       a. For the avoidance of doubt, You are not required to license 
Collective Databases under this License if You incorporate this Database 
or a Derivative Database in the collection
