Hi Experts
    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)  Best if it can do for both Oracle and Sql Server , but Oracle is good enough
I have seen the full version of Toad doing similar things . But can any free tool do this ?
(Oracle 11g or Sql Server 2008 are the databases versions)
your help is appreciated
Watch Question

For Oracle you can use "Oracle SQL Developer" - it's a free tool. And to generate your ER diagram follow these steps -

File --> Data Modeler --> Import --> Data Dictionary --> select DB connection --> Next --> select database -->select tables --> Finish


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