Use External Routines

The PL/SQL is particular for the SQL transaction processing. Therefore, several tasks are more quickly completed in a lower-level language like C that is very efficient at the machine-precision calculations.

The PL/SQL extends the functionality of the Oracle server by providing an interface for calling routines written in other languages. The Standard libraries by now written and available in other languages can be called from the PL/SQL programs. These promote reusability, efficiency, & modularity.

To speed up execution, you can rewrite the computation-bound programs in C. In calculation, you can move these programs from client to server, where they will execute more rapidly thanks to less across-network communication and more computing power.

For illustration, you can write methods for an image object type in C, store them in a DLL (dynamic link library), register the library with the PL/SQL, and then call it from your applications. At run time, the library load dynamically and, for safety, runs in an individual address space.
