New Version of SQL Developer Data Modeler is available!

It is now version 17.2!

Don’t worry, you have not missed 13+ releases!

A new versioning number system has been put in place and applies to both SQL Developer and SQL Developer Data Modeler (SDDM). A new version will come out about four times a year and the version number is created using the last two digits of the year and the number of the quarter.

So version 17.2 = Q2 2017

You can get the newest version here:

SQL Developer

There is also a new version (17.2) for this tool as well. Get it here:

Download and have fun!

Another Free Tip for SQL Developer Data Modeler (and a Challenge)

So here is another tip on using Oracle SQL Developer Data Modeler – but this time it is one I will NOT be showing during my session at #KScope13.

In SDDM there is a really nice wizard for building views. Once your view is built, you should probably test it right?

You could generate the DDL, or use DDL Preview, then open up SQL Developer, run the script to build the view, then select from the view to see the results.

Lotta steps, eh?

Or you could simply use the Test Query button on the View Properties dialog.

Press the button, then select a database connection from the drop down list (or create a new one if you need to). This will create a connection to the database and cause the SQL in the view to be executed. If everything works you will see “Query executed successfully”.

The Test Query button will first check that the SQL will execute

The Test Query button will first check that the SQL will execute

If you want to see the output of the query, just click the Query Results tab.

The Query Results tab lets you examine the output without opening another tool

Pretty cool. And must faster than the old way.

Now for the Challenge:

  1. You must be attending KScope13.
  2. You must be the first person to find me onsite in New Orleans and tell me you read this post.
  3. You then have to show up at my Top Ten Tips session at the conference, join me at the podium and tell the attendees this tip!

Your reward:

  1. It might be your first chance to present at an international conference.
  2. I will buy you the adult beverage of your choice that evening and chat about SDDM (or another topic of your choosing).

Not a million dollars, but who knows where it might lead or who else you might meet along the way.

So, who’s up to the challenge?

See you in New Orleans.

Oh – if oyu missed the first tip, it is here.


P.S. Jeff (@thatJeffSmith) and Chet (@OracleNerd) – sorry guys but you are not eligible! (I may buy you beer anyway)

The best FREE data modeling tool ever

Yup, I said FREE!

Oracle just released the latest and greatest version of SQL Developer Data Modeler  (SDDM) and it is free to the world to not only download but to use in your production environment to develop all your models.

As many of you know, I have been using this tool for several years now and have mentioned it many times on various LinkedIn forums (just search for me and check out my activity). I have used SDDM for both Oracle and SQL Server. For forward engineering and reverse engineering. For conceptual, logical, and physical data models.

I think it is a great tool (even if it was not free).

I loved Oracle Designer and got quite good at that, but once shops stopped buying and using Designer (and Oracle pretty much sun-setted the tool), I suffered for a few years using other tools.

I was a very happy camper when Oracle came out with this new data modeling tool. I am even happier now with the new features they have added.

The one I like the most, so far, is the visual editor they added for defining views. The previous version had a decent declarative approach that allowed you to specify tables, columns, and joins, but you could not really “see” the implied data model.

The newest version of SDDM (version 3.1) has added in a visual editor that shows you a diagram of the tables, columns, and joins. So now when you open (or define) a view and press the “query” property button you get drag and drop interface to build the view and a nice visual diagram.

And the best part is when you upgrade your existing models from previous versions, the old views automatically get diagrammed.

To get the best out of the new version you need to run a one time utility labeled “Parse Older Style Views”. You can find that off the right mouse menu in any diagram with views. It runs very fast and basically reads the SQL for your views then parses it out to show up properly in the diagram.

One nice new feature with the parsed views is that if the underlying tables in the view are part of the same design file (hopefully you did not drop those), then the view object on your diagram will now list those tables below all the columns. This is nice because now I do not have to open the view definition to see which tables the view is pulling from.

The other great new feature is the “Test Query” button on the view property dialog.

No more writing views that do not work. You press the button, specify a database connection to use, then the base query for the view fires.

If there is an error in your syntax, or a table you don’t have access to, you find out immediately.

So gone are the days of writing the view in your modeling tools, loging into SQL Plus or SQL Developer, testing the view, having it fail, then going back to SDDM to fix it.

Now you can do agile view development! In one tool!


Oh, and if the view works, there is a data tab so you can see the actual data the view will produce – live. Right in the data modeling tool.

Pretty cool.

Nice job guys.

Convinced yet? Head over to the Oracle site and download your own copy and give it try.

UPDATE 2015: Data Modeler is now up to version 4.1 and going strong. Plus now there is an Oracle Press book available on Amazon:

And I even have a tips and tricks Kindle book out on SDDM. You can find that here.

Let me know what you think in the blog comments.

Talk to you all later.


P.S. For all the new features in SDDM 4.1 check out the full list over here.
