The SAS Data Integration Studio SCD Type 2 Loader transformation can do which of the following?

Question

Options

• Agenerate cpu statistics
• Bgenerate a datetime value
• Cgenerates cluster numbers
• Dgenerates standardization values

• A
  3% (1)
• B
  89% (32)
• C
  3% (1)
• D
  6% (2)

Explanation

Option B is correct because the SCD Type 2 Loader transformation in SAS Data Integration Studio is designed to track historical changes to dimension data - and central to that process is generating datetime values (such as effective start and end timestamps) to mark when each version of a record was valid. Without datetime generation, Type 2 slowly changing dimension logic cannot function, since the entire approach relies on timestamping record versions.

Options A, C, and D are distractors that describe capabilities belonging to entirely different tools: CPU statistics are a system-monitoring concern (not an ETL loader's job), cluster numbers relate to database storage organization or analytical clustering algorithms, and standardization values are produced by data quality/cleansing transformations - none of these are within the scope of an SCD loader.

Memory tip: SCD Type 2 is fundamentally about tracking when something changed - so think "Type 2 = Timestamps," and you'll immediately recall that datetime value generation is its core capability.
