Data Duplication and Coherency Maintenance


It follows from the previous sections that information in each row of the Folder object TC are duplicates of properties in a child object. While this duplication of information allows efficient enumeration of sub-objects without having to enumerate and examine the sub-object nodes one-by-one, this duplication of information also requires additional effort to keep both copies of the information in sync. Implementations MUST ensure that changes to the underlying child object are correctly reflected in the parent Folder object TC.
