Question

What is the difference between a full refresh and an incremental refresh?

1) A full refresh updates all the data in a system, while an incremental refresh only updates the new or modified data.
2) A full refresh updates only the new or modified data, while an incremental refresh updates all the data in a system.
3) A full refresh and an incremental refresh are the same and can be used interchangeably.
4) A full refresh and an incremental refresh are two different terms for the same process.

Answer 1

A full refresh updates all the data in a system, while an incremental refresh only updates the new or modified data.

Step-by-step explanation:

The difference between a full refresh and an incremental refresh lies in the extent of the data updates. A full refresh involves updating all data in a system, regardless of whether it is new or modified. On the other hand, an incremental refresh only updates the new or modified data in the system.

For example, let's say you have a database with 100 records and you perform a full refresh. It would update all 100 records, even if only 10 of them were modified or new. However, if you were to do an incremental refresh, it would only update the 10 modified or new records.

Therefore, option 1) is correct: a full refresh updates all the data, while an incremental refresh focuses on the new or modified data.
