I believe rewriting SQL statements can also be a recommendation to reduce scattered reads.

SQL Patches? Really? I thought we were trying to optimize the queries, not just slap a bandaid on them. Let's aim a bit higher, shall we?

Partitioning tables, eh? That's like rearranging the bookshelves in the library - it might help, but it's not gonna stop the books from being scattered all over the place.

Materialized views, huh? That's an interesting one. Could be a good way to cache some of that data and reduce I/O. Worth considering, for sure.

The SQL Tuning Advisor is definitely the way to go here. I'm hoping to see some index and SQL rewrite recommendations to tackle those pesky scattered reads.
