The document outlines the principles and practicalities of launching a data catalog and implementing data mesh strategies to enhance data governance. It emphasizes decentralization, domain-centric ownership, and collaboration among teams to improve data accessibility and quality while eliminating silos. Key considerations include identifying stakeholders, standardizing data products, and adopting agile methodologies for governance.

3. Why Data Mesh?
What is the problem?
Monolithic approaches to data
don’t scale socially
Data is treated as an afterthought
Why do we care?
Centralized processes and teams become a
bottleneck for the business
Data value is being left untapped

4. Distribute responsibility for data pipelines and data quality to people with domain knowledge.
Serve data as a product using a common self-service IT infrastructure platform.
Domain-Centric
Ownership &
Architecture
Data as-a-Product Self-Service
Data Platform

Governance
Data pipelines owned by
teams with domain knowledge
Domains own cleansing,
refinement, historization,
pre-aggregation, etc.
Domains responsible for
governance, lineage, etc.
Domains treat data with
consumers in mind
Data is discoverable
Data is easy to obtain and use
Data is documented
Domains responsible for the
quality of their data
Common set of tools across
domains
Domain-agnostic
Easy to use and low
maintenance to support
Easy to deploy repeatable
patterns for data cleansing,
transformation, automation,
storage, security, governance,
sharing
Global interoperability
standards across domains
Define and use global data
governance policies
Define and apply governance
within each domain and
propagate downstream

5. DATA GOVERNANCE CHALLENGES
5
Data Is
Everywhere
Must be able to eliminate
silos inside and outside
your organization
Managing Data Is
Unnecessarily Complex
Knowing what your
data is — and how it is
being used — is hard
Security and Governance
Are Inherently Rigid
Requires managing risk and
changing regulations, while
getting the most from your data

6. DATA GOVERNANCE IN THE DATA CLOUD
6
Know Your Data Protect Your Data
Understand, classify, and
track data and its usage
Secure sensitive data with
policy-based access controls
Securely collaborate and
share data across teams
Unlock Your Data

7. What is has been...
Risk avoidance and compliance
Top-down policies
Cumbersome processes
DATA GOVERNANCE

8. What it needs to be...
DATA GOVERNANCE
Rules of cooperation and collaboration
Process of data & analytics together
Capture knowledge in real-time

9. What is the goal of data governance
Data Governance and Data Catalogs
What do catalogs do and how they help
Governance is now about data discoverability; not just data
protection.
While application silos pose a governance challenge, inclusive,
agile data governance approaches pose solutions.
Governance needs to be a benefit, not a burden. The friction
has to go away.
Business users don’t want to install software for governance,
SaaS removes all the friction and is the way to go.
Understand and trust your data with profiling, sampling and
lineage.
Everyone (producers and consumers) actively contributes to
data as they use it.
Accelerates time to value and uncover insights.
Cloud-native and multi-tenant approach are highly available,
scale bigger, perform better and evolve faster.

• Domain-centric ownership of data sources, pipelines, and data quality
• Ownership sits with domain knowledge 🡪 better data quality for consumers
• Domain teams can react faster to source format changes or quality issues
• Overall easier to scale the number of sources & consumers
• Data assets offered as products
• “Serve & pull” instead of
“push & ingest” model

16. 2. Who are the stakeholders?

17. datadotworld data.world
Capture and store what user
data exists, where is it, and
who is responsible for it?
Privacy
Tell me where is the sensitive
data, how is it handled, who
has access, who is
responsible for it?
Provide a platform to store
and share data best
practices, certifications,
documentation, and curated
data models.
Tell me what data there is, its
usability, how to use it and
who to go to for help.
Tell me who uses my data,
and give me a platform to
interact with them.
Enable automation within
data systems – registration,
provisioning, validation,
access controls, etc.
Stakeholders
Key to buy-in, executive sponsorship, and oversight.

Data Governance
Data Producers
Data Consumers
Data Leadership

18. 3. Where should we standardize and productize data?

19. datadotworld data.world
What is a Data Product?
“A product that facilitates an end goal
through the use of data”
DJ Patil, former United States Chief Data Scientist
“Data as a product defines a new
concept, called data product that
embodies standardized characteristics
to make data valuable and usable.”
Zhamak Dehghani, Thoughtworks Director of Emerging
Technologies and founder of data mesh

Snowflake Data Sharing as the preferred interoperability standard. Data Marketplace makes data discoverable.
Data Exchange / Catalog for
Consumers
• Connects providers to consumers
• Inventory of available assets
• No central storage of shared data
• Providers retain full control over shared
assets (data, functions)
• Consumers access live provider data, no
copies or ETL required. Register shared
data for local SQL access in their
environment (no copy)
Data domains:
• Can consume and share data or
functions
• Control access policies, data masking,
etc. for downstream consumers
• Can share external tables, i.e. provide
access to data outside of Snowflake
• Can provide reader accounts for
non-Snowflake consumers

• Technical Metadata Inventory, Lineage,

Who is responsible?
Whether you call them data product managers, data stewards, data owners, data
advocates, data custodians, or data trustees…
Let’s revisit Accountability of the Data Product ABCs Framework:
● Who is the owner?
● Who defines the requirements?
● Who fixes it when it breaks?
● Who defines the roadmap?
● Who has the expertise?
What are the fewest number of critical “hats to wear”?

The Cloud Data Catalog
What is Agile Data Governance?
The process of creating and improving data
assets by iteratively capturing knowledge as
data producers and consumers work together
so that everyone can benefit.
Empowering the usage of data safely.
It adapts the deeply proven best practices of
Agile and Open software development to data
and analytics.
