Re: Are there programs to graph database schema?

I know that there are standard ways to graph relational databases.

It occured to me that perhaps programs existed which simply parsed the
table definitions and plotted the graphs for you.

Anyone know of such a thing?

Thanks.

If I need to create an [E]ER-Modell from an existing databasae,
I mostly use MS Visio professional. It can reverse engineer via
ODBC lots of DBS.

Hi, I use MS Visio Professional, and it works (not very good), but it works.
I ever wondered if there is a opensource tool, that let me create an
automatic ER-Model diagram from an existing DB, like MS Visio.
Do you know if this tool exists ?

Thanks

Hi,

For a small schema, i've used PGACESS. There is a graphical editor which help
you to draw boxes with the foreign keys.

Guten Tag Juan Miguel,

Unfortunately I don't. I am unsatisfied with Visio too, but the point
of reason for using it is exactly that I don't know a better tool.
If anybody does - please let me know!

pg_autodoc

http://www.rbt.ca/autodoc/index.html

can produce .dot files that can be charted using
graphviz.

http://www.graphviz.org/

It works pretty well for medium sized databases
but for large it tends to produce a spaghetti.

Check the "Related Sites" in graphviz.org homepage.

Hi All ,

Have a look at DbVisualizer-4.0.2
Java based ER tool that works very well.

hello tony,

Our tool DeZign for Databases can do this for you. With the ImportER
Scripts add-on you can import SQL scripts containing create table
statements etc into the data modeling tool DeZign for Databases.
