Question #: 35
Topic #: 2

You are designing an extract, transform, load (ETL) process for loading data from a SQL Server database into a large fact table in a data warehouse each day with the prior day's sales data.
The ETL process for the fact table must meet the following requirements:
✑ Load new data in the shortest possible time.
✑ Remove data that is more than 36 months old.
✑ Ensure that data loads correctly.
✑ Minimize record locking.
✑ Minimize impact on the transaction log.
You need to design an ETL process that meets the requirements. What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A. Partition the destination fact table by date. Insert new data directly into the fact table and delete old data directly from the fact table.
