Mario works with a group of R programmers tasked with copying data from an accounting system into a data warehouse.

In what phase are the group's R skills most relevant?

  • A . Extract.
  • B . Load.
  • C . Transform.
  • D . Purge.

Show Answer Hide Answer

Suggested Answer: C

Explanation:

C. Transform

The R programming language is used to manipulate and model data.

In the ETL process, this activity normally takes place during the Transform phase.

The Extract and Load phases typically use database-centric tools.

Purging data from database is typically done using SQL.
