Declaring and Initializing Objects:
An object type is once defined and installed in the schema; you can use it to declare the objects in any PL/SQL, subprogram, block or package. For illustration, you can use the object type to specify the datatype of a column, attribute, variable, bind variable, table element, record field, formal parameter, or function result. At the run time, instances of the object type are formed that is, the objects of that type are instantiated. Each object can hold various values. These objects follow the usual scope and instantiation rules. In a subprogram or block, the local objects are instantiated whenever you enter the block or subprogram and cease to exist when you exit. In a package, the objects are instantiated when you first reference the package and cease to exist whenever you end the database session.
