The management of the application server, the cost of writing the code, and the increased complexity of the client program can be overridden entirely by the stored procedures in the DBMS. You can use Java,python,perl or c to write stored procedures, but you usually use a specific language specified by your DBMS. Oracle uses PL/SQL,POSTGRESQL to use procedural SQL using PL/PGSQL,DB2.
