What is the primary advantage of creating data rules within Information Analyzer as opposed to creating them within the Data Rules stage?

- Rules created within Information Analyzer can be tested and debugged on non-operational data in a testing environment before they are put into production.
- Rules created in the DataStage Data Rules stage have to be compiled into an executable form before they can be used.
- The variables in rules created in DataStage Data Rules stage must first be bound to data columns or literals before they can be run.
Correct answer: B
