For Oracle you can use &quot;Oracle SQL Developer&quot; - it's a free tool. And to generate your ER diagram follow these steps -<br />
<br />
File --&gt; Data Modeler --&gt; Import --&gt; Data Dictionary --&gt; select DB connection --&gt; Next --&gt; select database --&gt;select tables --&gt; Finish

Thanks. But It looks Sql Developer will show the column names and constraints of each table. &nbsp;If there is a foreign key in Tbl2 &nbsp;refering to Primary key in Tbl1 , can it show the link?

Hi Experts<br />
&nbsp; &nbsp; Is there any free tool which can automatically build the ERD (Enterprise Relationship diagram) of a Database ? (What I was looking is a diagram which shows the relationships based on Foreign keys) &nbsp;Best if it can do for both Oracle and Sql Server , but Oracle is good enough<br />
I have seen the full version of Toad doing similar things . But can any free tool do this ?<br />
(Oracle 11g or Sql Server 2008 are the databases versions)<br />
your help is appreciated
