Watch full webinar here: https://bit.ly/3dMN503 Advanced data science techniques, like machine learning, have proven an extremely useful tool to derive valuable insights from existing data. Platforms like Spark, and complex libraries for R, Python, and Scala put advanced techniques at the fingertips of the data scientists. However, these data scientists spend most of their time looking for the right data and massaging it into a usable format. Data virtualization offers a new alternative to address these issues in a more efficient and agile way. Watch this session to learn how companies can use data virtualization to: - Create a logical architecture to make all enterprise data available for advanced analytics exercise - Accelerate data acquisition and massaging, providing the data scientist with a powerful tool to complement their practice - Integrate popular tools from the data science ecosystem: Spark, Python, Zeppelin, Jupyter, etc

AI and Machine Learning Needs Data
Predicting high-risk patients
Data includes patient
demographics, family history,
patient vitals, lab test results,
past medication history, visits
to the hospital, and any claims
data
Predicting equipment failure
Data may include
maintenance data logs
maintained by the technicians,
especially for older machines.
For newer machines, data
coming in from the different
sensors of the machine—
including temperature,
running time, power level
durations, and error messages
Predicting default risks
Data includes company or
individual demographics,
products they purchased/
used, past payment history,
customer support logs, and
any recent adverse events.
Preventing fraudulent claims
Data includes the location
where the claim originated,
time of day, claimant history,
claim amount, and even public
data such as the National
Fraud Database.
Predicting customer churn
Data includes customer
demographics, products
purchased, product usage,
customer calls, time since last
contact, past transaction
history, industry, company
size, and revenue.

Typical data science workflow
Atypical workflow for adata scientistis:
1. Gather the requirements for thebusiness problem
2. Identify usefuldata
▪ Ingest data
3. Cleansedata into ausefulformat
4. Analyze data
5. Prepare input for your algorithms
6. Executedata science algorithms (ML, AI, etc.)
▪ Iterate steps 2 to 6 untilvaluable insights are
produced
7. Visualize and share

Where does your time go?
80% of time – Finding and preparing the data
10% of time – Analysis
10% of time – Visualizing data

10. 10
Where does your time go?
A large amount of time and effort goes into tasks not intrinsically related to data
science:
• Finding where the right data may be
• Getting access to the data
• Bureaucracy
• Understand access methods and technology (noSQL, REST APIs, etc.)
• Transforming data into a format easy to work with
• Combining data originally available in different sources and formats
• Profile and cleanse data to eliminate incomplete or inconsistent data
points

Logical Data Integration: the Path to the Future
Adopt the Logical Data Warehouse Architecture to Meet Your
Modern Analytical Needs”. Henry Cook, Gartner April 2018

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”

Ingestion and data manipulation tasks
• Data virtualization offers the unique
opportunity of using an easy to use
graphical UI and standard SQL (joins,
aggregations, transformations, etc.) to
access, manipulate and analyze any data
• Cleansing and transformation steps can be
easily accomplished in SQL
• Its modeling capabilities enable the
definition of views that embed this logic to
foster reusability

Prologis launches data analytics program for cost optimization
Background
• Create a single governed data access layer to create reusable and
consistent analytical assets that could be used by the rest of the
business teams to run their own analytics.
• Save time for data scientists in finding , transforming and analysing
data sets without having to learn new skills and create data models
that could be refreshed on demand.
• Efficiently maintain its new data architecture with minimum
downtime and configuration management.
Prologis is the largest industrial real estate company
in the world, serving 5000 customers in over 20
countries and USD 87 billion in assets under
management.

Data virtualization benefits experienced by Prologis
• The analytics team was able to create business focussed subject areas with consistent data
sets that were 30% faster in speed to analytics.
• Denodo made it possible for Prologis to quick start advanced analytics projects.
• Stable and scalable operationalisation of their data science project
• The Denodo platform’s deployment was as easy as a click of a button with centralized
configuration management. This simplified Prologis’s data architecture and also helped bring
down the overall maintenance cost.

sources – readily available to your data analysts and data scientists
✓ Can leverage Big Data technologies like Spark (as a data source, an
ingestion tool and for external processing) to efficiently work with
large data volumes
✓ Data virtualization shortens the ‘data wrangling’ phases of analytics/ML
projects
✓ Avoids needing to write ‘data prep’ scripts in Python, R, etc.
✓ Provides a modern “SQL-on-Anything” engine
✓ Extends and integrates with the capabilities of notebooks, Python, R, etc. to
improve the toolset of the data scientist
✓ New and expanded tools for data scientists and citizen analysts: “Apache
