+#### Declaring Objects For Types Defined In Schema
+After an object type is defined and installed in the schema, you can use it to
declare objects in any SQL block. For example, you can use the object type to
specify the datatype of an attribute, column, variable, bind variable, record
field, table element, formal parameter, or function result. At run time,
instances of the object type are created; that is, objects of that type are
instantiated. Each object can hold different values.
+
+Example: For declared types `address_typ` and `employee_typ`
+```SQL
+CREATE TYPE address_typ AS OBJECT (
+ street VARCHAR2(30),
+ city VARCHAR2(20),
+ state CHAR(2),
+ postal_code VARCHAR2(6) );
+
+CREATE TYPE employee_typ AS OBJECT (
+ employee_id NUMBER(6),
+ first_name VARCHAR2(20),
+ last_name VARCHAR2(25),
+ email VARCHAR2(25),
+ phone_number VARCHAR2(20),
+ hire_date DATE,
+ job_id VARCHAR2(10),
+ salary NUMBER(8,2),
+ commission_pct NUMBER(2,2),
+ manager_id NUMBER(6),
+ department_id NUMBER(4),
+ address address_typ
+);
+```
+
+We can declare objects of type `employee_typ` and `address_typ` :
+
+```SQL
+employee_typ(315, 'Francis', 'Logan', 'FLOGAN',
+ '555.777.2222', '01-MAY-04', 'SA_MAN', 11000, .15, 101, 110,
+ address_typ('376 Mission', 'San Francisco', 'CA', '94222'))
+```
