is diff backup better or adviced for OLAP (where there are batch processing and bulk inserts) because it will be easy for SQL to track what has changed since last FULL backup, instead of OLTP (like amazon.com)

It depends on the data recovery requirements.

In OLTP when there are multiple pages in the database updated, the differential backup tends to be considerably huge which is not the case in OLAP. (The Log backups also might be huge because of the transactions)

However, data recovery is needed in both environments.

Skipping differential backups is not advisable in most cases. Diff backups help in making the data recovery process faster compared to the log backups.

you mean Full backup+diff backup+tran log backup is faster than Full backup+tran log - and only for OLAP (where there are batch processing- huge inserts etc instead of individual transactions)
