The Data Warrior

Changing the world, one data model at a time. How can I help you?

End Your Data Modeling Pain

Tired of hand drawn data models, or models drawn in Visio or even PowerPoint?

Still limping along on an old Oracle Designer repository?

Can’t afford the license for your current modeling tool anymore?

Or maybe your shop has no documented data model diagrams at all (horrors!).

Well, if you were an Oracle Designer user and are looking for a replacement data modeling tool, or you are using one of the other mainstream, expensive modeling tools and want a more cost effective alternative, then you owe it to yourself (and your organization) to look at Oracle SQL Developer Data Modeler (SDDM). Data Modeler has been around for over five years now and is up to version 4.1. It really is an industrial strength data modeling tool that can be used for any data modeling task you need to tackle.

As I have mentioned before (many times) in this blog, SQL Developer Data Modeler (SDDM) is a fully functional modeling tool provided for FREE by Oracle. It has many features built in that can be leveraged to capture the design of an existing (probably undocumented) database and re-engineer it or you can use it to design a new database, even a data warehouse from scratch. There are features to apply standards, and then generate DDL to implement your newly standardized design. You can even use one logical model to develop multiple physical models that can be deployed to different RDBMS (like Oracle, SQL Server, and DB2). You even have options on the type of notation used in the diagrams (i.e., Barker, IE, etc.).

Unfortunately there are no comprehensive, end-to-end classes that can teach you how to really get started with SDDM and can point you to some of the awesome features and show you how they work.

Not until NOW!

Announcing my new online class: Introduction to Oracle SQL Developer Data Modeler.

This course will start from a totally blank page and walk you through all the major features and options of the tool to show you how to design build and deploy a database. I provide lots of examples and tips on how to do all this so that you can quickly be productive (while you watch!).

In this class, I will introduce you to the tool and show you how to use some of the cool features I use almost daily. I will provide step-by-step instructions on how to use these features. The class includes both lectures with screen shots and hands on demos of the tool (recorded live by me). Hint: some of my best tips are in the demos.

In this course you will see:

  • How to create new objects (entities, attributes, relationships) from a blank page
  • How to reverse engineer and document existing databases
  • How to reverse engineer logical models from physical to get a clean ERD
  • How to reconcile an existing data model to the database or the database to a model
  • How to generate a script to change an existing database

Tips, tricks and features I demonstrate include:

  • Modifying the delivered reporting templates
  • How (and when) to use the abbreviations utility
  • How to use and apply domains
  • How to create and applying object naming templates
  • How to add audit columns to every table in a model
  • How to add custom design rules for model quality checks
  • How to use the built in quality checks
  • How to use the newest find and extract feature to enable updating table and column comments by end users
  • How to generate a simple data dictionary

As an added bonus, in addition to step by step slides, and the demos, I have included a zip file with example output, templates, and DDL scripts that I created during the demos. You will be able to download these to your machine to try the exercises yourself.

If you have questions along the way, our modern learning management system (LMS) lets you enter your questions in the course comments whenever you want. I will get an immediate email notification so I can promptly answer your questions.

Unlike typical user group presentations, where I can only scratch the surface or show a few tricks, this course contains over four and a half hours of content broken up into bite-sized modules so you can easily digest the detailed information. If it does not make sense, you can simply play the same segment over again and even follow along on using your own install of SDDM.

By the end of the course you will be able to effectively use Oracle SQL Developer Data Modeler for all your data modeling tasks.

So head over to Learn Data Vault and check out the preview video of the class, then sign up and learn. Use my special offer code of GRAZIANO10S to get 10% off.

See you online!

P.S. The current price of the course is the initial sale price. I am not sure when the price will go up but Dan and Sanjay tell me that I set the price too low and they will have to raise it in the near future. So, I would sign up now, before that price goes up.

Meet me in Austin?

Late breaking news (aka I forgot to post this earlier)!

I will be speaking at the first meeting of the Austin Oracle Users Group for 2015. It will be this coming Friday February 27, 2015 starting at 11:00 AM. I will give an intro talk on Oracle SQL Developer Data Modeler (the FREE data modeling tool from Oracle).

So if you ever wanted to find out if this is the data modeling tool for you, join me in Austin and find out first hand.

After my talk there will be a free lunch, followed by a talk on “Leave the Crowd: Join the Cloud” by Lakshmi Sampath, ERP Cloud Evangelist and Brent Grech, VP, Fusion Applications, Global Sales Engineering, Oracle.

I plan to stick around for that talk too!

The meeting will be held at the Oracle offices at 9600 North MOPAC, Plaza II, Suite 700.

So please RSVP and let them know you are coming.

If you want to meet up after the session, leave me a comment below, or drop me a line.

See you soon!

The 12 Steps to Faster Data Warehouse Success

Announcement!

I have exciting news!

With the help of my good friend Dan Linstedt (of LearnDataVault.com fame), we have just launched my first online training video based on my very popular white paper and talk: Agile Methods and Data Warehousing: How to Deliver Faster.

Most of you will agree that data warehousing and business intelligence projects take too long to deliver tangible results. I am sure all you project and program managers wish it was not true.

Often by the time a solution is in place, the business needs have changed.

With all the talk about Agile development methods, including SCRUM and Extreme Programming, the question arises as to how these approaches can be used to deliver data warehouse and business intelligence projects faster. This new online course will look at the 12 principles behind the Agile Manifesto and see how they can be applied in the context of a data warehouse project. Then I will talk about some of the specific agile techniques I have used with great success on my projects over the last 15 years. The goal is to determine a method or methods to get a more rapid (2-4 week) delivery of portions of an enterprise data warehouse architecture.

The last time I gave this talk, in Helsinki, Finland at Harmony 2014, I had standing room only and ended up being rated the 2nd best speaker at the event (pretty cool!). It was so popular that the UK Oracle Users Group asked me to write an article on the same topic for their international newsletter.

Since many of you don’t get the chance to travel to events like this (or may have missed my session), you can now see my talk online, at your convenience, for much less than the cost of a conference fee (and the airfare to get there!). We just filmed it last week, after I completed my most recent agile data warehouse engagement, so it contains some new insights and stories that even the folks in Helsinki did not get to hear.

As a bonus, once you have finished the course, you will be able to download a free copy of the detailed article I wrote for UKOUG.

If you have questions during or after the course, you can post them right there in the training portal where I will answer them. So in addition to the training course and the white paper, you also get interactive access to me!

How do I sign up?

So how do you sign up for this new class and how much does it cost?

Well, the full price for course will be $199, but for those of  you who read my blog, I have a special Valentines Day Special offer: if you are one of the first 50 people to purchase the class between now and midnight February 15, 2015, you get a full 50% off the retail price.

So that is $99.50 for over an hour of valuable content PLUS a copy of my white paper (and access to ask me your burning questions).

Use the coupon code: GRAZIANO50

You can buy it now by going to the all new Learn Data Vault training portal now.

On the site you see the class description, outline, and my introductory video, along with the “Buy Now!” button.

So hurry and cash in my special gift to you before the time is up (remember after 2/15/15 it will be $199).

Applying Agile

For those of you who had no idea there were 12 Principles behind the Agile Manifesto, let me tell you about one that I think is vitally important: Principle #6

The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.

This means the team works best when co-located so they can easily talk to each other during the day.

HINT: If not co-located, you need to be sure you have an adequate instant messaging system in place to facilitate their daily interaction. And that the team agrees to use it!

In addition, another best practice is to hold Team Huddles every morning. In the class, I give a lot of details about huddles and how they work, but the main point is that the team needs to meet briefly once a day (usually the morning) to make sure they are all one the same page as to what they are all working on.

I can tell you for a fact, that the daily huddles and ongoing interaction is definitely a critical success factor in adopting agile practices for your data warehouse team. I have seen great success where this was implemented properly and I have also seen lots of issues when the team did not communicate daily. There is no better recipe for disaster than to have your data architect building the wrong view when the report writer is trying to finalize the output with the user. Yikes!

So, if you want to learn how to apply the 12 Principle of Agile to become more successful in delivering usable results to your data warehouse and BI program, please go over to the training site and sign up from my class.

Here’s to your success!

RMOUG Training Days 2015

Held every year at the Denver Convention Center in mid-February, The Rocky Mountain Oracle Users Group Training Days is the best value around for user group events – low cost ($395- $455), great locations (Denver!), and excellent speaker lineup (international speakers, Oracle ACE and ACE Directors).

I will be speaking both Wednesday, February 18, and Thursday, February 19 (last session!). My topics this year will be an Introduction to SQL Developer Data Modeler, and Worst Practices in Data Warehouse Design.

Plus I will be leading Morning Chi Gung exercises at 7 AM both days to get you all warmed up for a great day of learning. Check the entire agenda here.

As a bonus there are some excellent deep dive sessions on Tuesday, February 17th that are not to be missed, so get there early.

New this year will be Special Interest Group (SIG) meetings during lunch on Wednesday. I will be co-leading one on Data Integration & Data Warehousing with Bobby Curtis.

So, lots to do see and learn. Sign up today (and bring your ski equipment for the weekend after).

2nd Annual World Wide Data Vault Consortium

WWDVC was so successful last year, that Dan decided to do it again. This year there is even a new cool website for the event, which will be held May 28-30 in Stowe, Vermont at the Trapp Family Lodge. This will be a small event (less than 60 people), with a single track so you won’t have to decide which talk to attend.

Yes, the hills will be alive with the sounds of Data Vault geeks from around the world telling their tales of trials, tribulations, and success as they try to implement large, agile, enterprise data warehouse programs across many industries. Topics include:

  • Big Data, NoSQL
  • Virtualization of Data Marts
  • Data Vault 2.0 & Agility
  • Changing roles of Data Modeling
  • Managed Self-Service BI

The speaker lineup is a who’s-who of the data warehouse and agile world.

Special guests this year include a keynote from Claudia Imhoff, Dan Linstedt,  and newest addition Scott Ambler (one of the authors of the Agile Manifesto).

I will be there again, giving two talks with my buddy from McKesson, Keith Hoyle. We will discuss Data Warehousing in the Real World and talk about our endeavors to develop Virtualized Hybrid Type 1-2 Dimensions to enable Extreme BI.

Don’t miss this chance to rub elbows and network with the top innovators and thinkers in the data warehouse and BI space. Sign up soon as there are limited slots and limited rooms at the inn.

ODTUG KScope15

Another amazing annual event, this user group gathering will be a veritable who’s-who in the Oracle community. Again you will find Oracle ACEs and ACE Directors, as well as Oracle Product Managers, all ready and willing to discuss the latest and greatest tools for doing Oracle development work. Check out the amazing list of talks and presenters.

This year it is back to the beach for KScope. It will be held June 21-25 at the Diplomat Resort and Spa on the beach in Hollywood, Florida.

By popular demand, the last day of the conference will be all Deep Dive sessions, so be sure to plan your travel to hang out until the end (and then enjoy the beach!).

I will be giving two talks during the week (same ones as at RMOUG), answering questions on a panel or two, and again running my annual Morning Chi Gung sessions every morning (but this year outside on the beach).

This should be a very educational and relaxing event as it is every year. And it is in a family-friendly location so bring the gang along.  You can register today and still get a huge early registration discount.

So what are you  waiting for?

See you soon!

New Year, New Name, Same Mission

Happy New Year!

Looks like it will be another busy one. So, let’s get going!

Yes, I just changed the name of my blog from “Oracle Data Warrior” to “The Data Warrior.”

Why?

Well, for one, my company name is Data Warrior LLC, so it seemed to make sense.

Plus over the last few years quite a few of you that I see at conferences and such, simply call me “data warrior”. As in,

Hey, Data Warrior, how’s the battle going?

And after a some recent conversations and pondering, I realized that, while I am an Oracle ACE Director, and a fan of Oracle databases and tools, the things I write about and the work I do, is really database agnostic.

Think about it…

Regardless of the database, or data modeling tool, good design principles,  architecture, and standards transcend the technology.

Third normal form

Dimensional

Data Vault

Anchor

There are standards and best practices that are applied in developing all of these models that have nothing to do with technology. (Yes, implementing them efficiently is another story).

Some of my favorite topics, like FKs in data warehouses, and naming standards, are somewhat philosophical, and apply in many situations.

But never fear, you will still see posts on my favorite tool, SQL Developer Data Modeler,  and reports from all the main Oracle events (RMOUG, ODTUG, OOW).

And there will be the occasional rants about badly behaving data models and data modelers.

And of course Data Vault, Agile BI, and varying forms of virtualization.

Plus the occasion inspirational quote.

So while the name has changed, the content will not; the mission will not.

My mission is still to Change the World, One Data Model at a Time.

Let’s see what the year will bring us.

Kent

The Data Warrior

P.S. Look for future posts about upcoming talks I am giving, and at least one surprise new offering.
