I know for select statements, we can use indexes for the most queried columns and I know how to implement of all types. What all other measures can be taken and other objects created and used for better performance w.r.t DDL and DML statements. Please try and give entire list with brief description. Also, please point out a smaller sized textbook or manual using which i can make oracle work faster within the least time. Internal performance tuning is the other question you will find.
