Dan Horne writes about Case Studio ...
"I have found Case Studio to be an outstanding tool in its market niche.
It supports a wide variety of databases, although I've only use it with Oracle,
where I have found it to be excellent.

It's a bargain at $299, and with additional licenses costing only $89, it is well
within the budget of most organizations that do not require an enterprise solution.

I've been searching for a data modelling tool for some time, but most are not within
my price range, and are generally aimed at larger companies.
The competitive products I have found are marginally cheaper, but do not support the
fundamental features I need such as the reverse engineering of existing databases.

The only weakness is the documentation, which is included as a help file.
Some topics such as exporting the diagrams to a graphic file are not covered, and there is
no detail on writing templates to enhance and extend the system.

Likewise, Data Flow Diagrams are barely touched on.
Nevertheless, I am very pleased with my purchase.

Case Studio deserves to be much better known than it is.
