SQL Server Equivalence

Question

Hello,
I would like to have the equivalence of the default data type generated as such in SQL Server.
CREATE TYPE NANOU.TYPEDEVARIABLE [VARCHAR15] FROM [varchar](15) -- Here, in SQL Server, one wants to have a type starting from 15 length of character.
Create or replace type TYPEDEVARIABLE is table of varchar2(15) -- Here, in Oracle creates a type taking a length of 15 characters. Are both sentences the same? If not, what is the best way to implement this in Oracle?
Regards,

Perhaps if you can give a short example of how you would use it in SQL server, including create table and a couple of insert and select statements using the type someone could give you a better Oracle equivalent.
For example, if you use the object type as Ganesh suggested, you get needto do stuff like this on Oracle:
SQL> CREATE TYPE name_type AS OBJECT (
  2     name VARCHAR2(50));
  3  /
Type created.
SQL> CREATE TABLE emp (
  2     id NUMBER,
  3     last_name name_type,
  4     first_name name_type);
Table created.
SQL> desc emp
Name                    Null?    Type
ID                               NUMBER
LAST_NAME                        NAME_TYPE
FIRST_NAME                       NAME_TYPE
SQL> insert into emp VALUES (1, 'Smith', 'John');
insert into emp VALUES (1, 'Smith', 'John')
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected
OPS$ORACLE.NAME_TYPE got CHAR
SQL> insert into emp VALUES (1, name_type('Smith'), name_type('John'));
1 row created.
SQL> SELECT * FROM emp;
        ID LAST_NAME(NAME)       FIRST_NAME(NAME)
         1 NAME_TYPE('Smith')    NAME_TYPE('John')Update get complicated.
