Watch full webinar here: https://bit.ly/34iCruM Many organizations are embarking on strategically important journeys to embrace data and analytics. The goal can be to improve internal efficiencies, improve the customer experience, drive new business models and revenue streams, or – in the public sector – provide better services. All of these goals require empowering employees to act on data and analytics and to make data-driven decisions. However, getting data – the right data at the right time – to these employees is a huge challenge and traditional technologies and data architectures are simply not up to this task. This webinar will look at how organizations are using Data Virtualization to quickly and efficiently get data to the people that need it. Attend this session to learn: - The challenges organizations face when trying to get data to the business users in a timely manner - How Data Virtualization can accelerate time-to-value for an organization’s data assets - Examples of leading companies that used data virtualization to get the right data to the users at the right time

What is the ‘Last Mile’?
Term from Logistics domain
• Getting the product from the Distribution Center to the
customer.
• Personalized deliveries rather than bulk shipping.
Also used in Telecoms
• The ‘gap’ from the broadband switch to the home or
office.
• Or, the wireless gap between the wireless base station
and the user’s mobile device.

5. 5
Why is the Last Mile Important?
This is delivering the requested product to the customer
• In our case, delivering data to the user.
• Change from bulk movement of data (ETL/ELT)to
delivering data specific to users needs.
This used to be ‘Data Marts’ – extracted subsets of data for a
specific use.
But, the information ‘landscape’ is getting more complex, more
diverse, and more distributed.
• The old ETL to the Data Warehouse and then ETLto create
Data Marts doesn’t cut it anymore…

“You’re too slow, too
expensive, and never
deliver what I want.”
“You can’t make up your
mind, keep adding
features, and never see
the big picture.”
Casual User:
“Just forget it.”
Power User:
“Just give me a data dump.”
BU Leader:
“We’ll do it ourselves.”
“I’d rather be doing
something else than
taking your order.”
“You’ll come crawling
back to us soon.”
Why is this a Problem?

Gartner – Logical Data Warehouse
“Adopt the Logical Data Warehouse Architecture to Meet Your Modern Analytical Needs”. Henry Cook, Gartner April 2018
DATA VIRTUALIZATION

10. 11
- Gartner, Adopt the Logical Data Warehouse Architecture to
Meet Your Modern Analytical Needs, May 2018
“When designed properly, Data Virtualization can speed data
integration, lower data latency, offer flexibility and reuse, and
reduce data sprawl across dispersed data sources.
Due to its many benefits, Data Virtualization is often the first
step for organizations evolving a traditional, repository-style
data warehouse into a Logical Architecture”

11. 12
Benefits of a Virtual Data Layer
§ A Virtual Layer improves decision making and shortens development cycles
• Surfaces all company data from multiple repositories without the need to replicate all
data into a data warehouse or data lake.
• Eliminates data silos allows for on-demand combination of data from multiple sources.
§ A Virtual Layer broadens usage of data
• Improves governance and metadata management to avoid “data swamps”.
• Decouples data source technology. Access normalized via SQL or web services.
• Allows controlled access to the data with low grain security controls.
§ A Virtual Layer offers performant access
• Leverages the processing power of the existing sources controlled by Denodo’s optimizer.
• Processing of data for sources with no processing capabilities (e.g. files)
• Caching and ingestion engine to persist data when needed.

22. How Does Execution Work

23. 26
What is the Scenario?
The DV system only stores Metadata
Data is external
• Needs to travel through the Network
• To address: minimize network traffic
Data is distributed in multiple systems
• Needs to be integrated in the virtual layer
• Some sources have processing capabilities
• To address: maximize processing at sources to reduce load in virtualization layer

24. 27
What Information Do We Have?
1. The incoming query (SQL)
2. Table metadata
§ Source, PK, FK, indexes, “virtual” partitions, etc.
3. Data statistics
§ Used by the Cost Based Optimizer to estimating data volumes
4. Source capabilities
§ Can the source process data? (eg. RDBMS vs. CSV file)
§ “Read-Only” vs. “Can create temp tables”
§ In an MPP, size of the cluster

25. 28
What is the Optimizer Doing?
SELECT c.state, AVG(s.amount)
FROM customer c JOIN sales s
ON c.id = s.customer_id
GROUP BY c.state

Why is this so important?

FROM customer c JOIN sales s
ON c.id = s.customer_id
GROUP BY c.state
