You work as an application developer for Dolliver Inc. The company uses an oracle database. You own subprograms that reference to other subprograms on remote locations. Oracle server uses the signature mode of remote dependency in order to manage remote dependencies among the subprograms. Which of the following statements about the signature mode of dependency are true? (Choose two)
A. Oracle Server records only the signature for each PL/SQL program unit.
B. Using the signature mode prevents the unnecessary recompilation of dependent local procedures, as it allows remote procedures to be recompiled without affecting the dependent local procedures.
C. Signature mode is the default mode of remote dependency.
D. Oracle server records both the timestamp and the signature for each PL/SQL program unit.

B. The NULL value in the expression column is a stored NULL value.
C. The expression has not been used to calculate the aggregate value.
D. The NULL value in the expression column is changed by ROLLUP or CUBE as a result of grouping.
Concatenation of grouping sets is very helpful for these reasons:
A. Ease of query development: You need manually enumerate all groupings.
B. Use by applications: SQL generated by online analytical processing (OLAP) applications often involves concatenation of grouping sets, with each GROUPING SET defining groupings needed for a dimension.
