Answer / sravan

These transactions are widely used in performance tuning of
any program.
We use ST05 tcode to SQL trace. we use SQL trace to analyse
the time consumed by various select statements in program.
If any select statement is taking long time to retrieve data
from Database, we can re-look into that and make necessary
changes.

We use SE30 for runtime analysis. This is for overall
evaluation of program. By using this, we can know about time
consumed by various processes (dialog,select) .Best practice
is make the time consumed by SQL statements very less.
