Information Management

As IoT applications become more pervasive, there is a real-time big data explosion Internet of Things


Almost anything can be equipped and connected to the Internet Real-Time Big Data Explosion Real-time data analysis is an integral part of many IoT applications They can generate, in real-time , streams and streams of data © 2014 IBM Corporation

Information Management

Information Management

What is different in IoT data?

There are many extremes

There are greater amounts

of data


Process and act on data

more quickly in real time



more types

Information Management Traditional versus IoT Big Data Traditional Approach IoT Big Data Approach

Analyzed Information Available Information

Analyze Small Subsets of Information

Analyze ALL Available Information

Analyze All Information Leverage more of the data being captured

Information Management Traditional versus IoT Big Data Traditional Approach IoT Big Data Approach

Analyzed Information Analyzed Information A Small Amount of Carefully Cleansed Information

Carefully Cleanse Information Before Any Analysis

A Very Large Amount of Messy Information

Analyze Information As Is, Cleanse As Needed Reduce effort required to leverage data

Information Management Traditional versus IoT Big Data Traditional Approach IoT Big Data Approach

Analyze data AFTER it has been processed and landed in a Warehouse or Mart Analyze data IN MOTION as it is generated, in real-time Leverage data as it is captured

Information Management RE 8

Standard assumptions

Clean and correct data Transactional guarantees Normalized, structured data Explicit relationships kept ACID properties Centrally managed storage Store-and-process Reliable hardware Query, insert, delete with SQL Reference/context data on disk

Re-think for IoT data analysis

Take advantage of and tolerate uncertainty Good enough Store data in elemental form Relationships found at query Relaxed constraints Loosely distributed data Process in motion Built with full expectation of failures Query, operators, analytics at point of data Reference and context data in memory © 2014 IBM Corporation

Information Management InfoSphere Streams: For superior real time analytic processing

Streams Processing Language (SPL) built for Streaming applications: Reusable operators Rapid application development Continuous “pipeline” processing

Use the data that gives you a competitive advantage:

Can handle virtually any data type Use data that is too expensive and time sensitive for traditional approaches

Compile groups of operators into single processes:

Efficient use of cores Distributed execution Very fast data exchange Can be automatic or tuned Scaled with push of a button

12 Easy to extend:

Built in adaptors Users add capability with familiar C++ and Java

Easy to manage:

Automatic placement Extend applications incrementally without downtime Multi-user / multiple applications

Flexible and high performance transport:

Very low latency High data rates

Dynamic analysis:

Programmatically change topology at runtime Create new subscriptions Create new port properties

Information Management University of Ontario Institute of Technology (UOIT) Detects Neonatal Patient Symptoms Sooner 16

“Helps detect life threatening conditions up to 24 hours sooner”

• Performing real-time analytics using physiological data from neonatal babies • Continuously correlates data from medical monitors to detect subtle changes and alert hospital staff sooner • Early warning gives caregivers the ability to proactively deal with complications © 2014 IBM Corporation

Information Management Challenges and opportunities  Approach overload – Is there a convergence of approaches?

– Is there a “write once, use any technology” approach across tool types  Skills to apply techniques – Reduce the skill required?

– More people who can be data scientists, developers, and business/domain savvy?  Uncertain data – Confidence levels need to follow data and decisions  New analytic algorithms – Real time learning and adaptation?

– More automation  Availability – What does it mean for in-memory systems?

– How should disaster recovery work?

 Cloud – Security of Data – Data movement  Data governance, security, and privacy  What new problems can we solve?
