    <p>By very large, I mean on the realm of thousands of tables. I've been able to use Toad Data Modeler to do the reverse engineering, but once it loads up the txp file it creates, it just croaks. Even attempting to split up the model isn't possible as TDM just sits, frozen.</p> <p>So, I was wondering what other options are out there, and perhaps if there are any 32 bit applications that can handle such a database model (considering the memory used by this is ~750MB, I would think it not too large for a 32 bit computer with max RAM).</p> <p>Also to note, I am not trying to create a diagram with this (such a huge diagram would be effectively useless unless you already knew the system), but am instead needing to export the design of the database. So the data model tool doesn't need to support any sort of fanciful graphics, which may not be possible with the given size anyways.</p> <p>Edit: I've found a potential solution which leads to TDM working. You have to close the project, close TDM, open TDM, and then open the project. If you just kill the process while it is frozen, this will not work. What this does is zoom the screen showing the graphical representation to the normal view level, while normally after reverse engineering, the entire database is put into the view (if you just kill the process, when you open up the file again, you will see the entire database). While I am not certain the details, it appears being zoomed it makes it so that TDM runs much smoother and does not freeze or crash, and as such I am able to keep working in it to do what I need.</p>

    1. COWhen you say Toad croaks, do you mean literally? I think there's an option to disable that. :)

    2. COExactly what kind of data are you looking for? If you just want the table DDL, you can try DBMS_METADATA.GET_DDL.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
