Against the backdrop of Big Data, the Chief Data Officer, by any name, is emerging as the central player in the business of data, including cybersecurity. The MITCDOIQ Symposium explored the developing landscape, from local organizational issues to global challenges, through case studies from industry, academic, government and healthcare leaders. Joe Caserta, president at Caserta Concepts, presented "Big Data's Impact on the Enterprise" at the MITCDOIQ Symposium. Presentation Abstract: Organizations are challenged with managing an unprecedented volume of structured and unstructured data coming into the enterprise from a variety of verified and unverified sources. With that is the urgency to rapidly maximize value while also maintaining high data quality. Today we start with some history and the components of data governance and information quality necessary for successful solutions. I then bring it all to life with 2 client success stories, one in healthcare and the other in banking and financial services. These case histories illustrate how accurate, complete, consistent and reliable data results in a competitive advantage and enhanced end-user and customer satisfaction.

What’s New in Modern Data Engineering?

12. @joe_Caserta
What you need to know (according to Joe)
Hadoop Distribution: Apache, Cloudera, Hortonworks, MapR, IBM
 Tools:
 Hive: Map data to structures and use SQL-like queries
 Pig: Data transformation language for big data
 Sqoop: Extracts external sources and loads Hadoop
 Spark: General-purpose cluster computing framework
 Storm: Real-time ETL
 NoSQL:
 Document: MongoDB, CouchDB
 Graph: Neo4j, Titan
 Key Value: Riak, Redis
 Columnar: Cassandra, Hbase
 Search: Lucene, Solr, ElasticSearch
 Languages: Python, Java, R, Scala

Governing Big Data
 Before Data Governance
 Users trying to produce reports from raw source data
 No Data Conformance
 No Master Data Management
 No Data Quality processes
 No Trust: Two analysts were almost guaranteed to come up
with two different sets of numbers!
 Before Big Data Governance
 We can put “anything” in Hadoop
 We can analyze anything
 We’re scientists, we don’t need IT, we make the rules
 Rule #1: Dumping data into Hadoop with no repeatable process, procedure, or
governance will create a mess
 Rule #2: Information harvested from an ungoverned systems will take us back to
the old days: No Trust = Not Actionable

•This is the ‘people’ part. Establishing Enterprise Data Council,

•Ensure consistent business critical data i.e. Members,
Providers, Agents, etc.Master Data Management
•Data retention, purge schedule, storage/archiving
Information Lifecycle
Management (ILM)
Chief Data Officer – 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
for Big Data

 Only top tier of the pyramid is fully governed

Implementing Data Governance on Big Data
People, Processes and Business commitment is still critical!
Caution: Some Assembly Required
The V’s require robust tooling:
 Unfortunately the toolsets available
are pretty thin: Some of the most
hopeful tools are brand new or in
incubation!
Enterprise big data governance
implementations combine products
with some custom built components

Use Cases
• Real-Time Trade Data Analytics
• Comply with Dodd-Frank
• Electronic Medical Record Analytics
• Save lives?

23. @joe_Caserta
High Volume Trade Data Project
• The equity trading arm of a large US bank needed to scale its
infrastructure to enable the ability to process/parse trade data real-time
and calculate aggregations/statistics
~ 1.4Million/second ~12 Billion messages/day ~240 Billon/month
• The solution needed to map the raw data to a data model in memory or
low latency (for real-time), while persisting mapped data to disk (for end
of day reporting).
• The proposed solution also needed to handle
ad-hoc data requests for data analytics.

24. @joe_Caserta
The Data
• Primarily FIX messages: Financial Information Exchange
• Established in early 90's as a standard for trade data communication
widely used throughout the industry
• Basically a delimited file of variable attribute-value pairs
• Looks something like this:
8=FIX.4.2 | 9=178 | 35=8 | 49=PHLX | 56=PERS | 52=20071123-05:30:00.000 |
11=ATOMNOCCC9990900 | 20=3 | 150=E | 39=E | 55=MSFT | 167=CS | 54=1 | 38=15 | 40=2 |
44=15 | 58=PHLX EQUITY TESTING | 59=0 | 47=C | 32=0 | 31=0 | 151=15 | 14=0 | 6=0 |
10=128 |
• A single trade can be comprised of 100's of such messages, although
typical trades have about a dozen

Some Thoughts – Enable the Future
 Big Data requires the convergence of
data governance, advanced data
engineering, data science and business
smarts
 Make sure your data can be trusted
and people can be held accountable for
impact caused by low data quality.
It takes a village to achieve all the tasks
required for effective big data strategy
& execution
 Get experts that have done it before!
Achieve the impossible…..
… everything is impossible until someone does is!
