Top Five Cool Features in Oracle SQL Developer Data Modeler

Not to be confused with Oracle Database Vault (a commercial db security product), Data Vault Modeling is a specific data modeling technique for designing highly flexible, scalable, and adaptable data structures for enterprise data warehouse repositories. It is not a replacement for star schema data marts (and should not be used as such). This approach has been used in projects around the world (Europe, Australia, USA) for the last 10 years but is still not widely known or understood. The purpose of this presentation is to provide attendees with a detailed introduction to the technical components of the Data Vault Data Model, what they are for and how to build them. The examples will give attendees the basics for how to build, and design structures when using the Data Vault modeling technique. The target audience is anyone wishing to explore implementing a Data Vault style data model for an Enterprise Data Warehouse, Operational Data Warehouse, or Dynamic Data Integration Store. See more content like this by following my blog http://kentgraziano.com or follow me on twitter @kentgraziano.

Data modeling continues to be a tried-and-true method of managing critical data aspects from both the business and technical perspective. Like any tool or methodology, there is a “right tool for the right job”, and specific model types exist for both business and technical users across operational, reporting, analytic, and other use cases. This webinar will provide an overview of the various data modeling techniques available, and how to use each for maximum value to the organization.

Lessons in Data Modeling: Why a Data Model is an Important Part of Your Data ...

Data can provide tremendous value to an organization in today’s information-driven economy. New customer insights, better efficiency, and new product innovation are just some of the ways organizations are obtaining value through data. But in order to achieve this value, a strong data architecture is required to ensure that the data infrastructure runs smoothly, while at the same time aligning with business needs and corporate culture. A Data Strategy can assist in building a data architecture foundation through: Identifying business requirements, rules & definitions via a business-centric data model Creating a data inventory & integrating disparate data sources Building a technical data architecture through data models & related artifacts Coordinating the people, processes and culture necessary for success Identifying tools & technology needed for creating & maintaining high quality data

Data Catalog for Better Data Discovery and Governance

Watch full webinar here: https://buff.ly/2Vq9FR0 Data catalogs are en vogue answering critical data governance questions like “Where all does my data reside?” “What other entities are associated with my data?” “What are the definitions of the data fields?” and “Who accesses the data?” Data catalogs maintain the necessary business metadata to answer these questions and many more. But that’s not enough. For it to be useful, data catalogs need to deliver these answers to the business users right within the applications they use. In this session, you will learn: *How data catalogs enable enterprise-wide data governance regimes *What key capability requirements should you expect in data catalogs *How data virtualization combines dynamic data catalogs with delivery

Essential Reference and Master Data Management

Data tends to pile up and can be rendered unusable or obsolete without careful maintenance processes. Reference and Master Data Management (MDM) has been a popular Data Management approach to effectively gain mastery over not just the data but the supporting architecture for processing it. This webinar presents MDM as a strategic approach to improving and formalizing practices around those data items that provide context for many organizational transactions: its master data. Too often, MDM has been implemented technology-first and achieved the same very poor track record (one-third succeeding on-time, within budget, and achieving planned functionality). MDM success depends on a coordinated approach typically involving Data Governance and Data Quality activities. Learning objectives: - Understand foundational reference and MDM concepts based on the Data Management Body of Knowledge (DMBOK) - Understand why these are an important component of your Data Architecture - Gain awareness of Reference and MDM Frameworks and building blocks - Know what MDM guiding principles consist of and best practices - Know how to utilize reference and MDM in support of business strategy

Activate Data Governance Using the Data Catalog

Data Governance programs depend on the activation of data stewards that are held formally accountable for how they manage data. The data catalog is a critical tool to enable your stewards to contribute and interact with an inventory of metadata about the data definition, production, and usage. This interaction is active Data Governance in the truest sense of the word. In this RWDG webinar, Bob Seiner will share tips and techniques focused on activating your data stewards through a data catalog. Data Governance programs that involve stewards in daily activities are more likely to demonstrate value from their data-intensive investments. Bob will address the following in this webinar: - A comparison of active and passive Data Governance - What it means to have an active Data Governance program - How a data catalog tool can be used to activate data stewards - The role a data catalog plays in Data Governance - The metadata in the data catalog will not govern itself

Agile Data Engineering: Introduction to Data Vault 2.0 (2018)

(updated slides used for North Texas DAMA meetup Oct 2018) As we move more and more towards the need for everyone to do Agile Data Warehousing, we need a data modeling method that can be agile with us. Data Vault Data Modeling is an agile data modeling technique for designing highly flexible, scalable, and adaptable data structures for enterprise data warehouse repositories. It is a hybrid approach using the best of 3NF and dimensional modeling. It is not a replacement for star schema data marts (and should not be used as such). This approach has been used in projects around the world (Europe, Australia, USA) for over 15 years and is now growing in popularity. The purpose of this presentation is to provide attendees with an introduction to the components of the Data Vault Data Model, what they are for and how to build them. The examples will give attendees the basics: • What the basic components of a DV model are • How to build, and design structures incrementally, without constant refactoring

How a Semantic Layer Makes Data Mesh Work at Scale

Data Mesh is a trending approach to building a decentralized data architecture by leveraging a domain-oriented, self-service design. However, the pure definition of Data Mesh lacks a center of excellence or central data team and doesn’t address the need for a common approach for sharing data products across teams. The semantic layer is emerging as a key component to supporting a Hub and Spoke style of organizing data teams by introducing data model sharing, collaboration, and distributed ownership controls. This session will explain how data teams can define common models and definitions with a semantic layer to decentralize analytics product creation using a Hub and Spoke architecture. Attend this session to learn about: - The role of a Data Mesh in the modern cloud architecture. - How a semantic layer can serve as the binding agent to support decentralization. - How to drive self service with consistency and control.

Worst Practices in Data Warehouse Design

This presentation was given at OakTable World 2014 (#OTW14) in San Francisco. After many years of designing data warehouses and consulting on data warehouse architectures, I have seen a lot of bad design choices by supposedly experienced professional. A sense of professionalism, confidentiality agreements, and some sense of common decency have prevented me from calling people out on some of this. No more! In this session I will walk you through a typical bad design like many I have seen. I will show you what I see when I reverse engineer a supposedly complete design and walk through what is wrong with it and discuss options to correct it. This will be a test of your knowledge of data warehouse best practices by seeing if you can recognize these worst practices.

Agile Data Warehousing: Using SDDM to Build a Virtualized ODS

(This is the talk I gave at Houston DAMA and Agile Denver BI meetups) At a past client, in order to meet timelines to fulfill urgent, unmet reporting needs, I found it necessary to build a virtualized Operational Data Store as the first phase of a new Data Vault 2.0 project. This allowed me to deliver new objects, quickly and incrementally to the report developer so we could quickly show the business users their data. In order to limit the need for refactoring in later stages of the data warehouse development, I chose to build this virtualization layer on top of a Type 2 persistent staging layer. All of this was done using Oracle SQL Developer Data Modeler (SDDM) against (gasp!) a MS SQL Server Database. In this talk I will show you the architecture for this approach, the rationale, and then the tricks I used in SDDM to build all the stage tables and views very quickly. In the end you will see actual SQL code for a virtual ODS that can easily be translated to an Oracle database.

Agile Data Warehouse Modeling: Introduction to Data Vault Data Modeling

This is a presentation I gave at OUGF14 in Helsinki, Finland. Data Vault Data Modeling is an agile data modeling technique for designing highly flexible, scalable, and adaptable data structures for enterprise data warehouse repositories. It is a hybrid approach using the best of 3NF and dimensional modeling. It is not a replacement for star schema data marts (and should not be used as such).

The examples will give attendees the basics for how to build, and design structures incrementally, without constant refactoring, when using the Data Vault modeling technique. This technique works well for: • Building the Enterprise Data Warehouse repository in a CIF architecture • Building a Persistent Staging Area (PSA) in a Kimball Bus Architecture • Building your data model incrementally, one sprint at a time using a repeatable technique • Providing a model that is easily extensible without need to re-engineer existing structure or load processes

Data Warehousing 2016

These are the slides from my talk at Data Day Texas 2016 (#ddtx16). The world of data warehousing has changed! With the advent of Big Data, Streaming Data, IoT, and The Cloud, what is a modern data management professional to do? It may seem to be a very different world with different concepts, terms, and techniques. Or is it? Lots of people still talk about having a data warehouse or several data marts across their organization. But what does that really mean today in 2016? How about the Corporate Information Factory (CIF), the Data Vault, an Operational Data Store (ODS), or just star schemas? Where do they fit now (or do they)? And now we have the Extended Data Warehouse (XDW) as well. How do all these things help us bring value and data-based decisions to our organizations? Where do Big Data and the Cloud fit? Is there a coherent architecture we can define? This talk will endeavor to cut through the hype and the buzzword bingo to help you figure out what part of this is helpful. I will discuss what I have seen in the real world (working and not working!) and a bit of where I think we are going and need to go in 2016 and beyond.

Demystifying Data Warehouse as a Service (DWaaS)

This is from the talk I gave at the 30th Anniversary NoCOUG meeting in San Jose, CA. We all know that data warehouses and best practices for them are changing dramatically today. As organizations build new data warehouses and modernize established ones, they are turning to Data Warehousing as a Service (DWaaS) in hopes of taking advantage of the performance, concurrency, simplicity, and lower cost of a SaaS solution or simply to reduce their data center footprint (and the maintenance that goes with that). But what is a DWaaS really? How is it different from traditional on-premises data warehousing? In this talk I will: • Demystify DWaaS by defining it and its goals • Discuss the real-world benefits of DWaaS • Discuss some of the coolest features in a DWaaS solution as exemplified by the Snowflake Elastic Data Warehouse.

Pimping SQL Developer and Data Modeler

Kris Rice

Every development shop is unique, and sometimes that uniqueness can hinder using tools. SQL Developer and Data Modeler have multiple mechanisms that allow for customizations. These customizations can range from simple to complex and can help tailor the tooling to any environment. Some are as simple as colored warning to remind the user what is production vs. development. Some could auto-generate code by walking over a data model. The most complex can change anything at all in the tool. Ever think of a command that should be in SQL Plus scripting? Want to auto-generate table APIs?

Balance agility and governance with #TrueDataOps and The Data Cloud

DataOps is the application of DevOps concepts to data. The DataOps Manifesto outlines WHAT that means, similar to how the Agile Manifesto outlines the goals of the Agile Software movement. But, as the demand for data governance has increased, and the demand to do “more with less” and be more agile has put more pressure on data teams, we all need more guidance on HOW to manage all this. Seeing that need, a small group of industry thought leaders and practitioners got together and created the #TrueDataOps philosophy to describe the best way to deliver DataOps by defining the core pillars that must underpin a successful approach. Combining this approach with an agile and governed platform like Snowflake’s Data Cloud allows organizations to indeed balance these seemingly competing goals while still delivering value at scale. Given in Montreal on 14-Dec-2021

HOW TO SAVE PILEs of $$$BY CREATING THE BEST DATA MODEL THE FIRST TIME (Ksc...

A good data model, done right the first time, can save you time and money. We have all seen the charts on the increasing cost of finding a mistake/bug/error late in a software development cycle. Would you like to reduce, or even eliminate, your risk of finding one of those errors late in the game? Of course you would! Who wouldn't? Nobody plans to miss a requirement or make a bad design decision (well nobody sane anyway). No data modeler or database designer worth their salt wants to leave a model incomplete or incorrect. So what can you do to minimize the risk? In this talk I will show you a best practice approach to developing your data models and database designs that I have been using for over 15 years. It is a simple, repeatable process for reviewing your data models. It is one that even a non-modeler could follow. I will share my checklist of what to look for and what to ask the data modeler (or yourself) to make sure you get the best possible data model. As a bonus I will share how I use SQL Developer Data Modeler (a no-cost data modeling tool) to collect the information and report it.

Making Sense of Schema on Read

[Given at DAMA WI, Nov 2018] With the increasing prevalence of semi-structured data from IoT devices, web logs, and other sources, data architects and modelers have to learn how to interpret and project data from things like JSON. While the concept of loading data without upfront modeling is appealing to many, ultimately, in order to make sense of the data and use it to drive business value, we have to turn that schema-on-read data into a real schema! That means data modeling! In this session I will walk through both simple and complex JSON documents, decompose them, then turn them into a representative data model using Oracle SQL Developer Data Modeler. I will show you how they might look using both traditional 3NF and data vault styles of modeling. In this session you will: 1. See what a JSON document looks like 2. Understand how to read it 3. Learn how to convert it to a standard data model

Demystifying Data Warehousing as a Service - DFW

Using OBIEE and Data Vault to Virtualize Your BI Environment: An Agile Approach

First we interview the users, then we design a reporting model based on those interviews. We follow that up with mounds of ETL development to load the new model, basically keeping the user community in the dark during all that development. Does this sound familiar? This presentation will demonstrate an alternative approach using the Data Vault Data Modeling technique to build a flexible, easily-extensible “Foundation” layer in our data warehouse with an Agile, iterative methodology. Relying on the Business Model and Mapping (BMM) functionality of OBIEE, we can rapidly virtualize a dimensional reporting model using the pattern-based Data Vault Foundation layer to decrease the time, and money, it takes to get BI content in front of end users. Attendees will see a sample Data Vault model designed iteratively and deployed to the semantic model of OBIEE.
