In the load and index stage of ETL, what is the difference between refresh mode and update mode?

What will be an ideal response?

Refresh mode is an approach to filling a data warehouse that involves bulk rewriting of the target data at periodic intervals. Initially, the warehouse is filled. Then, at periodic intervals, the warehouse is rewritten, replacing the previous contents. Update mode, on the other hand, only writes changes to the source data without overwriting old data.
