Question 21: You are designing the data model for a retailer's catalog application. A description of all products for
sale will be stored in the Documentum repository. There are thousands of different types of products.
Each product may have a unique set of attributes. Users should be able to add or remove attributes from
a product definition at runtime.
Which approach should you use to provide the required flexibility in data types, and also provide good
query performance when searching for product information?
A. You create a type called product that contains all common attributes and attach and detach attribute
aspects as required. For searching, you use the TRY_FTDQL_FIRST DQL hint.
B. You use XML content stored in an XML store, add and remove attributes by modifying the XML content,
and use IDfXQuery to search for product information.
C. You use lightweight objects with the parent object containing common attribute values. Parent objects
are created for each product description. For searching, you use NOFTDQL queries.
D. You create a standard object type hierarchy and issue alter type statements, as needed, to modify
types at runtime. For searching, you use FTDQL queries.
Correct Answer: B
