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

Business & Data Strategies
A BUSINESS STRATEGY is a medium to long term business plan which
details the aims & objectives of a business and how it means to
achieve them.
A DATA STRATEGY is a medium to long term plan for the improvement,
management & exploitation of data across a business, and how it is
to be achieved.

“Creative” Data Model for Business Audience
• Using a “graphical data model” is an intuitive way to show data entities and their relationships to
a business audience.
• It’s a helpful way to show how data fits into the “big picture” of the organization & helps it run
effectively.

Data Definitions - why bother?
The Tower of Babel
“If as one people
speaking the same
language they have
begun to do this, then
nothing they plan to do
will be impossible for
them. Come, let us go
down and confuse their
language so they will not
understand each other.”
Genesis 11:1-9
20. Global Data Strategy, Ltd. 2016
The Importance of Definitions
• Definitions are as important as the data elements themselves.
• Many data-related business issues are caused by unclear or ill-defined terms
20
What is in a name?
What do you mean by
“customer”?
We’re calculating “total sales”
differently in each region!
Sales is using a different
“monthly calendar” than
Finance.
How are we defining a
“household”?
What’s an “equity
derivative”?
What’s a “PEG ratio”?
“API” as in “Application Programming Interface?”
or “American Petroleum Institute”? Or a bee?
What’s the difference between an
“ingredient” and a “raw material”?
21. Global Data Strategy, Ltd. 2016
Data Definitions – The Benefits
• Helps scope the data strategy to focus on the data objects / attributes
that really matter
• Supports the development and enforcement of data standards &
business rules
• Enables selective data quality scrutiny & monitoring
• Prioritizes data improvement activities
• Underpins business and IT impact analysis & change control
• Informs and improves design gateways and approvals
• Better legal & regulatory control, especially if combined with Data
Governance
• If published and communicated, helps to raise general awareness of the
importance of key data
21
23. Global Data Strategy, Ltd. 2016
Data Modeling Creates an “Active Inventory” of Data Assets
• Know what data you have: Create a visual inventory of database systems
• Know what your data means: Communicate key business requirements between business and IT
stakeholders
• Support data consistency: Build consistent database structures & support data governance

Metadata Adds Context & Definition
• Metadata stored in data models provides valuable business & technical context.
24
25. Global Data Strategy, Ltd. 2016
Technical & Business Metadata
• Technical Metadata describes the structure, format, and rules for storing data
• Business Metadata describes the business definitions, rules, and context for data.
• Data represents actual instances (e.g. John Smith)
25
CREATE TABLE EMPLOYEE (
employee_id INTEGER NOT NULL,
department_id INTEGER NOT NULL,
employee_fname VARCHAR(50) NULL,
employee_lname VARCHAR(50) NULL,
employee_ssn CHAR(9) NULL);
CREATE TABLE CUSTOMER (
customer_id INTEGER NOT NULL,
customer_name VARCHAR(50) NULL,
customer_address VARCHAR(150) NULL,
customer_city VARCHAR(50) NULL,
customer_state CHAR(2) NULL,
customer_zip CHAR(9) NULL);

“Sales Amount”
Transformation Rules
(ETL)
• Data Lineage shows the source to target mapping, or provenance for information.
• For example, to understand how “Sales Amount” in a data warehouse is calculated, it is necessary to
understand where the data came from and how it was manipulated along the way.
• Many data modeling tools track this lineage through integration with ETL tools, or with internal mapping
functionality.
27. Global Data Strategy, Ltd. 2016
Data Model Design Layer Relationships
• Data model design layer mappings show the relationship between business terms and their
physical implementations on a database platform.

In a Conceptual data model, there may
be a concept called “Client” which is the
term businesspeople use to describe the
people they sell to and work with.
The Logical model might
use the term “Customer”
for that same concept.
Which may be implemented in a number
of physical tables with varying naming
conventions.

Data Modeling for Data Warehousing & Business Intelligence
• What is the definition of customer?
• Where is the data stored?
• How is it structured?
• Who uses or owns the data?
Data Warehouse BI Report:
Customers by Region
• What are the definitions of key business terms?
• What do I want to report on?
• How do I optimize the database for these reports?
Data Modeling helps answer:
For Data Warehousing For BI Reporting
Data Modeling helps answer:
• Data Modeling is the “Intelligence behind Business Intelligence”
• Understand source and target data systems
• Define business rules
• Optimize data structures to align queries with reports
Show me all

Relational Model

30. Global Data Strategy, Ltd. 2016
Data Modeling for Enterprise Architecture
• Enterprise Architecture provides a high-level view of the people, processes, applications, and data
of an organization
• Putting data in business context
• How does data link to the rest of my organization?
• If I change data, what business processes are affected?
31. Global Data Strategy, Ltd. 2016
Data Modeling for Cloud and SaaS
Cloud Database
DB2
Sybase
SQL Server
Teradata
Oracle
• A Data Model is your “roadmap” for:
What data to move to the Cloud, and what to keep on-premises
Defining data structures (physical model) and business requirements (logical model) for Cloud databases
• Off-Premises doesn’t mean Out of your Control
Data Model
32. Global Data Strategy, Ltd. 2016
Data Modeling for Application Development
• The majority of today’s applications are data-driven
• Data Modeling is a key part of the application development lifecycle
• Reuse of common data objects helps promote
• Increased efficiency – don’t “reinvent the wheel”
• Better collaboration
• Increased quality and consistency
33. Global Data Strategy, Ltd. 2016
Data Modeling for Master Data Management
• Master Data Management strives to create a “single version of the truth” for key business data:
customer, product, etc.
• Using a central data model helps define:
• Common business definitions
• Common data structures
• Data lineage between defined “version of the truth” and real-world implementations
34. Global Data Strategy, Ltd. 2016
Data Modeling for Data Governance
• Data, like money, is a corporate asset, and needs to be managed accordingly.
• Like an auditing department for finance, data governance provides the guidelines, accountability
and regulations around data management.
• Data Models can help define:
• What are the standards, domains, and rules for data?
• Who is accountable for data (e.g. Data Steward)?
• Who is using data?
• What is the lineage and traceability of data?
• What is the proper definition of key business information?
• When was the data last updated?
