Exadata’s “secret sauce” for different workloads
 “DW / Reporing”
• Long running SQL statements
• Executed less frequently
• Secret Sauce: Smart Scans + Offloading + Storage Indexes
• SQL statements should use full table scans + hash joins

 “OLTP”
• Short SQL statements
• Executed very frequently
• Secret Sauce: Flash Cache
• SQL & performance tuning is the same as usual!
