ER Diagram

Toad for Oracle & DevOps Toolkit
1

Hi folks … I know how to generate ER diagram for existing tables in database
via TOAD.

But how can we create E-R diagram for new tables yet in Design Phase ?

Is there a way other than creating those tables and then generating the E-R
diagram ?

Regards,

Shiva

Hi Shiva,

from the help for the ER Diagrammer:

Note: This is not a modeling tool. See Integration with Toad Data
Modeler for more information about performing full data modeling on your
table structures.

If you want to add new tables, then I suspect you ned the TDM (Toad Data
Modeller) tool. There is a beta version that you can join the program
for and report problems, enhancements etc:

For more details, please read the Beta release announcement at:

Yes – buy toad data modeler (a full blown modeling tool) – or buy a
toad bundle where you get toad data modeler for free as part of the bundle

What’s built in toad is only meant to diagram existing tables – not
design a new database – that’s toad data modeler

Yes it is called Toad Data Modeler (TDM) http://www.quest.com/Toad-Data-Modeler/

In all seriousness though the data modeler (code road map) in Toad is just a
quick and dirty graphical representation of existing objects in the DB. For real
data modeling functionality you need something like TDM.
