tacobell fan Posted April 18, 2019 Report Posted April 18, 2019 1) How to handle the delta's or change data capture (CDC) 2) How to insert/update into table 3) Depends on datamart, SDC2 aithe how to maintain record history. 4) How to calculate dates for a record (start and end dates) if a start date is only given based on natural key 5) How to group by SUM or Cummulative summary for a record  Depends on the ETL tool it will be more specific. Also expect questions on Unix Scripting, SQL, Repository, Code migration, Release Process, Ticketing, Issue tracking, Testing. ETL doesn't necessarily mean they will stick to tool related questions.
