Automatically generate E-R diagram [message #500047]

Hi guys,

I would like to generate automatically at a certain interval a E-R diagram with all the tables in a schema and put the file on a certain location. My problem is the word AUTOMATICALLY. Toad Data Modeller does everything I want except this.

Can you suggest me a tool that might do that? It doesn't have to be free.

Thanks!

Tried it but has no option to generate the diagram automatically every week let's say and this is what I want.

Any other suggestions please?

What did I miss?

Could you please be more specific? I need a diagram with the tables and the relations between them.

Oracle 11g Standard Edition on Windows Server 2008.

I don't think it's related in any way to Oracle documentation. I need an external tool capable of creating a schedule for an E-R diagram. Hope my problem is clear.

I know how to schedule a task in Windows. Please provide me a solution for creating a scheduled task that would update an E-R diagram of all tables in a Oracle schema. If you can find any. Thanks.

Thank you Blackswan, SchemaSpy worked just fine for what I wanted.

I wrote a blog post about how to generate and update E-R diagrams automatically, feel free to download the batch file and use it:
