Photography was discovered in and soon after the phenomenon of photography was being experimented with and in turn brought new and different ways of photo taking not only as documenting real time, but also conceptualizing a scene in which an image would be taken.

These functions include building database objects like tables and queries, manipulating objects, inserting data to existing tables, updating existing data in tables, deleting existing data from tables, performing database queries, controlling database access, and overall database administration.

Any changes made to the parameter are returned to the calling program by default by copying but - with the NO-COPY hint - may be passed by reference.
