What is Big Data?
Volume
Exceeds physical limits of vertical scalability
Velocity
Decision window small compared to data
change rate
Variety
Many different formats makes integration
expensive
Variability
Many options or variable interpretations
confound analysis

Healthcare
and Big Data
Healthcare and IT
Often the laggard in technology
Yet application of IT to healthcare can radically change what we can do
Genomic Sequencing
Proteomic sequencing
Incidence Prediction
12
Healthcare Big Data Example Scenarios
Clinical Trial Deviations
Originally Viagra was developed to lower blood pressure and treat Angina
Now its used to help newborn pulmonary hypertension and altitude sickness
Incidence Prediction
Missed 4 or more visits, twice as likely to have an asthmatic incident
Particular Cardiac monitor sine wave points to highly likelihood of heart attack
Campaigns
Social media and advertising campaigns to understand user behavior and sentiment
Patient Satisfaction
Social media and advertising campaigns to understand user behavior and sentiment

BIDMC Auditing Scenario
Auditing is critical component HIPAA in ensuring patient privacy
1 Billion rows+ of audit data
146 mission critical clinical applications
Comprehensive audits yield 300-500k transactions/day
HIPAA requires audit system with 20 years of data
Auditing Project
Available to community as part of Compliance SDK
Updating for SQL Server 2012, HDInsight, Power View, and MobileBI*
Creating an enterprise tool for consolidated storage, reporting and alerting of all application audit
data - that's cool!

Use PowerPivot / Power View / Analysis Services to Query the data .
Use S SIS to process SQL2008 All-Actions Audit Information and other CG application
audit log data; potentially can use Management Performance DW framework.

Hadoop / Auditing: File sizes
Currently testing gz vs. raw
E.g. 12MB raw text file vs. 633Kb gz file (~20x compression)
Query
Duration (s)
select count(*) from sql_audit_asv_raw
56.066
select count(*) from sql_audit_asv_gz
58.994
20x smaller size, ~same query time
Approx same map / reduce task utilization
File Size is 250MB-1GB
SSIS package takes care of the size
Future testing: avro, protobuf
23

Hadoop / Auditing: Formats
For ease of processing, replace carriage returns within embedded SQL
statements, e.g.
select col1, col2
from tableA
to
select col1, col2 from tableA
This allows you to create a Hive table using CR as row delimiter (i.e.
does not have things like SQL quoted identifiers)
