A) Balanced Optimization creates a parameter set called BalOpJAQLParams in the underlying project if it does not exist.
B) Balanced Optimization will change or optimize machine configurations, InfoSphere DataStage configurations, database configurations, or HDFS configurations.
C) Balanced optimizations are performed in a priority order. When there is ambiguity (for example, some processing could be performed either in a source or target database) processing is pushed into database sources.
D) Balanced Optimization is installed with InfoSphere DataStage.

B) Surrogate keys are used to join a dimension table to a fact table in a normalized schema database

D) Each SCD stage processes multiple dimensions and performs lookups by using an equality matching

4. How do you create a shared table definition from the DataStage client?
