This document discusses using data modeling to build the foundations for strong data quality. It outlines a process with six steps: [1] defining metadata standards, [2] encouraging collaboration, [3] organizing models and data, [4] enforcing standards, [5] changing organizational culture, and [6] creating a "to be" target state. The key points are that data quality requires treating data as a valuable asset, establishing good metadata and modeling habits, and ongoing cultural changes rather than a single solution.

2. Abstract
• Data is a company’s greatest asset. Enterprises that can harness
the power of their data will be strategically positioned for the next
business evolution. But too often businesses get bogged down in
defining a data management process, awaiting some “silver bullet”,
while the scope of their task grows larger and their data quality
erodes. Regardless of your eventual data management solution is
implemented, there are processes that need to occur now to
facilitate that process. In this webinar we will discuss using your
current data modeling assets to build the foundations of strong
data quality.

3. Biography
• Victor Rodrigues brings 10 years of experience of advanced usage
of the CA ERwin Modeling suite first as a Senior Support Engineer
for the CA ERwin Modeling suite of products and currently as a
Senior Software Engineer for Programmer’s Paradise. In this time
he has used his extensive experience to implement the tool with
various large and small enterprises. This experience includes
customization of the CA ERwin tool via the API and Forward
Engineering template editor as well as maximizing modeling by
integrating the product suite which includes CA Model Validator,

5. Trusting Your Data

6. Data Quality Realities
• Data is a company’s greatest asset.
• Accenture survey shows 40% trust “gut” over BI.
• 61% say good data was not available.
• Data plus quality equals information.

7. Obstacles

8. Obstacles to Data Quality
• People, Process or Software related…
– All of the above.

9. Silver Bullets?
• Isn’t the Data Warehouse/ERP solution supposed
to be doing this?
– Definitions can be context specific.
– Delays taking ownership of your data.
 Nike/I2 CMS example.

13. The Steps

14. 1 – Defining Metadata Standards
PAGE 14

15. Why Metadata Matters
• Start by Defining Meta Data
– Disagreements as to what a definition is
• Too Conceptual – Definitions are not possible
• Too strict
– Everything can be defined.
PAGE 15

16. Strict Yet Flexible
• Too Strict Example.
– Phone number as a single entry.
• Too Flexible.
– Phone number as XML?

22. 2 - Collaboration
• Share designs and templates.
• Model lineage and history.
• Centralized reporting.
PAGE 22

23. Overcoming Silo Mentality
• Director of National Intelligence
• “A Space” encourages collaboration.
PAGE 23

24. Collaboration
• Updates to apps migrate to source DBMS models
and vice-versa.
• Define and enforce your glossary and standard
abbreviations.
• Create templates.
PAGE 24

25. 3 - Organization
• Build on Existing Processes
– You are already governing data (informally).
– Identify your assets.
PAGE 25

26. We Need Structure
• Add structure to your existing process.
• Link your models.
• Create libraries in your Model Manager that
contain linked application models, related DBMS
models, etc.
• Create your Model Manager security roles.

29. 4 - Enforcing Standards
• Generate diagram and repository reports to other
teams.
• Promote your value to your Business Analysis
teams.
• A bidirectional hub to report your standards and
update your policies.

30. 5 - The Hard Part – Cultural Change
• Data Quality requires a change of culture.
• There is no silver bullet. It is a process.
• Like any habit, it becomes easier with time.
• Replacing bad habits with good ones.
• The process must me bottom up and top down.
• NUMMI plant example
PAGE 30

31. Good Habits
• Model Everything • Own your (meta)data.
– Applications – Be a good shepherd.
– DBMS – Do not pass along bad data.
– Data Warehouses
– ERP systems
– Others
• NoSQL databases, UML
models, etc.
• Model your Data Entry.
– Valid Values?
– Nullability?
– Proper and matching

Datatypes/Domains.

32. 6 - Create Your “TO BE” Design
• Create the “To Be” model.
• Compare “As Is” and “To Be” environments
• Create a process.
PAGE 32

33. Conclusion
• Treat data like the asset that it is.
• Data quality creates information.
• Strong metadata definitions + good habits = data
quality.
• Data modeling allows us to structure our
metadata.
• Data quality is a process and requires cultural
changes.
