Answer / cbr
In SCD type 2 effective date approach the target table
structure should have kay column, ee_start_date,
eff_end_date and source columns.
1. eff_start_date will be "sysdate"
2. eff_end_date will be "future date"
ex: 01-01-3000(this is what the future date means)
i hope this will help you
