The Future of Data is Today
As a Mindful Cyborg, Chris
Dancy utilizes up to
700 sensors, devices,
applications, and services to
track, analyze, and optimize as
many areas of his existence.
Data quantification enables
him to see the connections of
otherwise invisible data,
resulting in dramatic upgrades
to his health, productivity, and
quality of life.

Traditional Data Analytics Methods
• Design – Top Down, Bottom Up
• Customer Interviews and requirements gathering
• Data Profiling
• Create Data Models
• Facts and Dimensions
• Extract Transform Load (ETL)
• Copy data from sources to data warehouse
• Data Governance
• Stewardship, business rules, data quality
• Put a BI Tool on Top
• Design semantic layer
• Develop reports

A Day in the Life
• Onboarding new data is difficult!
• Rigid Structures and Data Governance
• Disconnected/removed from business requirements:
“Hey – I need to analyze some new data”
 IT Conforms and profiles the data
 Loads it into dimensional models
 Builds a semantic layer nobody is going to use
 Creates a dashboard we hope someone will notice
..and then you can access your data 3-6 months later to see if it has value!

Houston, we have a Problem: Data Sprawl
• There is one application for every 5-10 employees generating copies of
the same files leading to massive amounts of duplicate idle data strewn all
across the enterprise. - Michael Vizard, ITBusinessEdge.com
• Employees spend 35% of their work time searching for information...
finding what they seek 50% of the time or less.
- “The High Cost of Not Finding Information,” IDC

OLD WAY:
• Structure  Ingest  Analyze
• Fixed Capacity
• Monolithic
NEW WAY:
• Ingest  Analyze  Structure
• Dynamic Capacity
• Ecosystem
RECIPE:
• Data Lake
• Cloud
• Polyglot Data Landscape

It’s the Change Agent

Innovation is the only sustainable competitive advantage a company can have
Innovations may fail, but companies that don’t innovate will fail

Technology:
• Scalable distributed storage  Hadoop, S3
• Pluggable fit-for-purpose processing  Spark, EMR
Functional Capabilities:
• Remove barriers from data ingestion and analysis
• Storage and processing for all data
• Tunable Governance

Does Data munging in a data science
lab need the same restrictive
governance and enterprise reporting?

•This is the ‘people’ part. Establishing Enterprise Data Council, Data Stewards, etc.Organization
•Definitions, lineage (where does this data come from), business definitions, technical
metadataMetadata
•Identify and control sensitive data, regulatory compliancePrivacy/Security
•Data must be complete and correct. Measure, improve, certifyData Quality and Monitoring
•Policies around data frequency, source availability, etc.Business Process Integration
•Ensure consistent business critical data i.e. Members, Providers, Agents, etc.Master Data Management
•Data retention, purge schedule, storage/archiving

Information Lifecycle
Management (ILM)
Data Governance
• Add Big Data to overall framework and assign responsibility
• Add data scientists to the Stewardship program
• Assign stewards to new data sets (twitter, call center logs, etc.)
• Graph databases are more flexible than relational
• Lower latency service required
• Distributed data quality and matching algorithms
• Data Quality and Monitoring (probably home grown, drools?)
• Quality checks not only SQL: machine learning, Pig and Map Reduce
• Acting on large dataset quality checks may require distribution
• Larger scale
• New datatypes
• Integrate with Hive Metastore, HCatalog, home grown tables
• Secure and mask multiple data types (not just tabular)
• Deletes are more uncommon (unless there is regulatory requirement)
• Take advantage of compression and archiving (like AWS Glacier)
• Data detection and masking on unstructured data upon ingest
• Near-zero latency, DevOps, Core component of business operations

Peeling back the layers… The Landing Area
• Source data in it’s full fidelity
• Programmatically Loaded
• Partitioned for data processing
• Little governance other than catalog and ILM (Security and Retention)
Consumers: ETL Processes, Applications

Data Lake
• Enriched, lightly integrated
• Data accessible via Hive or ‘raw’
• Either processed into tabular relations
• Or via Hive Serdes directly upon Raw Data
• Partitioned for data access
• Additional Governance
• Consumers: Data Scientists, ETL Processes,
Applications, Data Analysts

Data Science Workspace
• No barrier for onboarding and analysis of new data
• Blending of new data with entire Data Lake, including the Big Data
Warehouse
• Data Scientists enrich data with insight
Consumers: Data Scientists

Big Data Warehouse
• Data is Fully Governed
• Data is Structured
• Partitioned/tuned for data access
• Governance includes a guarantee of completeness and
accuracy, security

Insights
• The feedback loop between Data Science and Data Warehouse is critical
• Successful work products of science must Graduate into the appropriate
layers of the Data Lake

Define and Find Your Data
• Data Classification
• Import/Define business taxonomy
• Capture/Automate relationships between data sets
• Integrate metadata with other systems
• Centralized Auditing
• Security access information for every application with data
• Operational information for execution
• Search & Lineage (Browse)
• Predefined navigation paths to explore data
• Text-based search for data elements across data ecosystem
• Browse visualization of data lineage
• Security & Policy Engine
• Rationalize compliance policy at run-time
• Prevent data derivation based on classification (re-classification)
Key Requirements
• Automatic data-
discovery
• Metadata tagging
• Classification

Caution: Assembly Required
 Some of the most hopeful tools are brand new or in
incubation!
 Enterprise big data implementations typically combine
products with custom built components
Tools
People, Processes and Business commitment is still critical!
Data Integration Data Catalog & Governance Emerging Solutions

Existing On-Premise Solution
• Challenges with operations of data servers in Data Center
• Increasing infrastructure complexity
• Keeping up with data growth
Cloud Advantages
• Reduced upfront capital investment
• Faster speed to value
• Elasticity
“Those that go out and buy expensive
infrastructure find that the problem scope and
domain shift really quickly. By the time they get
around to answering the original question, the
business has moved on.” - Matt Wood, AWS
Move to the Cloud?
