What is scd type 2 and incremental load

Question

Accepted Answer

SCD type 2 is a method of tracking historical changes in data, while incremental load is the process of updating only new or changed data.

SCD type 2 involves creating a new record for each change in data, with a start and end date for each version.
Incremental load involves comparing new data to existing data and only updating or inserting new records.
Both are commonly used in data warehousing and ETL processes.
Example: tracking changes in customer addresses over time using SCD type 2, and only updating new orders in an incremental load process.
