Regarding the storage clause, you might get a number of replies saying to use locally 
managed tablespace, so let me start.
By now you should be using locally managed tablespaces with uniform allocation or 
automatic allocation depending on circumstances.
Here is a link to more info...

and/or just search that site.  This topic has been addressed there quite well.

And this link for good info on the table size itself...

Happy reading! (If you've never been to asktom, you'll find a lot of great information 
there.)

Hi Gurus ...

can somebody help in sizing the table/index using the storage clause ? what
r the key values to check and how to calculate the table size & the related
storage parameters ? how does it change from an OLTP appln to a
Datawarehouse ?

lets say for the table "emp" :
Name         Null?    Type
------------ -------- ------------
EMPNO        NOT NULL NUMBER(4)
ENAME                 VARCHAR2(10)
JOB                   VARCHAR2(9)
MGR                   NUMBER(4)
HIREDATE              DATE
SAL                   NUMBER(7,2)
COMM                  NUMBER(7,2)
DEPTNO                NUMBER(2)
