10. Which statement(s) is/are true related to Navigational attributes vs Dimensional attributes?
a. Dimensional attributes have a performance advantage over navigational attributes for queries
b. Change history will be available if an attribute is defined as navigational
c. History of changes is available if an attribute is included as a characteristic in the cube
d. All of the above
ANSWER(S): A, C
Dimensional attributes have a performance advantage while running queries since the number of table joins will be less compared to navigational attributes. For navigational attributes, the history of changes will not be available. But for dimensional attributes, the InfoCube will have the change history.
