Chapter 3

1. 1. [False] inheritance applies to types and not to objects.

2. 2. [True] dm_folder does not define any single-valued property of its own.

3. 3. [False] Security is enforced by the Content Server and this behavior is not dependent upon the mechanism of access (DFC or DQL).

4. 4. [09] The object type tag for dm_document and its subtypes is 09.

5. 5. [b] These properties are normally managed by Content Server for its internal purposes and not seen by the users or applications.

6. 6. [c] 4. Since records are shared by different properties, the total number of records is the maximum number of values present for any repeating property.

7. 7. [False] authors is a property inherited from dm_sysobject. dm_document does not have any properties of its own and thus no persistence tables of its own.

8. 8. [d] The first two hex digits in r_object_id represent a tag for the object type.

9. 9. [True] DQL can be used to query database tables directly, though the tables being queried need to be registered first.

10. 10. [True] A DQL query on a type queries its subtypes as well and dm_document is a subtype of dm_sysobject.
