#SQLDevModeler Tip: From Domain to Database… A Comment Conundrum

Great tip on creating a custom transformation script in SQL Developer Data Modeler (SDDM) from the awesome David Schleis:

Recently on the Data Modeler Forum, I came across this question:

Is it possible to mirror domain comments, from Domain Administration into attribute “Comments in RDBMS”?  Would like to mirror these to the ddl so they can be then available in column comments in the database.

I knew that one of the example transformation scripts provided with Data Modeler copies the column “Comments” property to “Comments in RDBMS”, so I thought I would point this out to the questioner, and that would be that.  But….

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

Data Modeler

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:

The best FREE data modeling tool on the planet just got better!

To be clear this is Early Adopter (EA) version 2 of SDDM 4.2. You can get it here right now!

#SQLDev Data Modeler New Features

Of course there are some bug fixes from EA1, but also some new features for you to enjoy:

Import from Oracle Database

  •   performance and filtering enhancements
  •   ability to define Oracle Client for thick connections
  •   view and materialized view driving query and columns now parsed and validated

Versioning

  •   improvements in performance
  •   new models are shown as a single node in pending changes window

Reporting

  • HTML report for tables now include diagrams

 

SQL Developer Data Modeler EA2 adds diagrams to HTML reports

#SQLDev Data Modeler HTML report with diagrams embedded

So go download and unwrap that present!

Cheers!

Adventures in the Cloud

I just got back from a whirlwind tour that included a trip to San Francisco to visit the Snowflake HQ, attend the annual Oracle ACE Directors briefing, meetings and events at Oracle OpenWorld (OOW), speaking at OakTable World (OTW), then off to Chicago to speak at Enterprise Dataversity.

Yes it was packed. And lots of talk about cloud everything!

 

Thanks to the great folks at OTN (Roland and Jennifer) for hosting us again this year at Oracle HQ.

Here are a few highlights:

Morning Chi Gung

Now an annual event is doing Chi Gung by the lake behind the Sofitel with a few ACE Director friends before the *top secret* briefing.

Pre-OOW Athletics

Well, sort of. This year I walked the Golden Gate Bridge (5K) and took a dip in SF Bay in the 5th Annual Swim The Bay. Proud to say I have attended all 5 years of that event.

Nothing like a brisk morning walk to start the day!

Then there is the brisk swim!

And this year, I got a pretty good size group to do Chi Gung on the beach after the swim (to warm ourselves back up!)

Time to get that chi flowing after the swim!

OTW 2016

I think this is the 3rd time I have presented at the un-conference run in parallel to OOW. But this year was the 1st time I did it as an Oaktable member! Gave my talk on Building a Virtualized ODS using SQL Developer Data Modeler.

No picture from that talk (sorry) but I did a very short Chi Gung set with the attendees at lunch time to get them moving out of their seats.

 

OTN Interview

This was the best part – getting to do an interview with my good friend Laura Ramsey from OTN about data modeling and data warehousing in the cloud. Check out my full interview here.

The Drake Hotel

For the Dataversity event in Chicago, I got to stay at the very classy Drake Hotel right on the lake shore with a great view.

Awesome View!

Awesome View!

Oh, and my talk on Data Warehousing in 2016 and Beyond went great. I learned a lot in the various keynotes and even got an introduction to Data Science.

 

Well that is my little update for now.

Check my speaking page to see where I will be next!

Ciao.

Better Data Modeling: Customizing Oracle Sql Developer Data Modeler (#SQLDevModeler) to Support Custom Data Types

On a recent customer call (for Snowflake), the data architects were asking if Snowflake provided a data model diagramming tool to design and generate data warehouse tables or to view a data model of an existing Snowflake data warehouse. Or if we knew of any that would work with Snowflake.

Well, we do not provide one of our own – our service is the Snowflake Elastic Data Warehouse (#ElasticDW).

The good news is that there are data modeling tools in the broader ecosystem that you can of course use (since we are ANSI SQL compliant).

If you have read my previous posts on using JSON within the Snowflake, you also know that we have a new data type called VARIANT for storing semi structured data like JSON, AVRO, and XML.

In this post I will bring it together and show you the steps to customize SDDM to allow you to model and generate table DDL that contain columns that use the VARIANT data type.

Read the details of how I did it here on my Snowflake blog:

Snowflake SQL: Customizing Oracle Sql Developer Data Modeler (SDDM) to Support Snowflake VARIANT – Snowflake

Enjoy!

P.S. If you are in Austin, Texas this weekend, I will be speaking at Data Day Texas (#DDTX16). Snowflake will have a booth there too, so come on by and say howdy!
