Procedures provide advantages in the following
areas:
1•security
Stored procedures can help enforce data security.
You can restrict the database operations that users can
perform by allowing them to access data only through
procedures and functions.
For example, you can grant users access to a
procedure that updates a table, but not grant them access
to the table itself. When a user invokes the procedure, the
procedure executes with the privileges of the procedure's
owner. Because users only have the privilege to execute the
procedure and not the privileges to query, update, or
delete from the underlying tables, users can invoke the
procedure, but they cannot arbitrarily manipulate table
data in any other way.
2•performance
Reduces network traffic as compared to no. of
individual SQL sent
Since procedure’s complied form is available in the
database, no compliation step required to execute the code.
If procedure is present in SGA then retrieval from
disk is not required and execution can begin immediately.
3•Memory allocation
Since stored procedures take advantage of shared
memory capabilities of ORACLE, only a single copy of the
procedure needs to be loaded into memory for execution by
multiple users.
4•productivity
Stored procedures increase development
productivity. By designing applications around a common set
of procedures, you can avoid redundant coding and increase
your productivity.
5•Integrity
By developing all of your applications around a
common group of procedures, you can reduce the likelihood
of committing coding errors.
