- Big data refers to large volumes of data from various sources that is analyzed to reveal patterns, trends, and associations. - The evolution of big data has seen it grow from just volume, velocity, and variety to also include veracity, variability, visualization, and value. - Analyzing big data can provide hidden insights and competitive advantages for businesses by finding trends and patterns in large amounts of structured and unstructured data from multiple sources.

2. What is Big Data?
“Large volumes of a wide variety of data collected from various sources across the enterprise including transactional data from enterprise applications/databases, social media data, mobile device data, unstructured data/documents, machine-generated data and more.“ Source: IDG: Big Data – Growing Trends and Emerging Opportunities

3. Data Sources
Structured
•Spreadsheets
•Relational Databases
•ERP
•CRM
•Legacy systems
•File share
Unstructured
•Documents
•Machine Data
•Messaging
•Photographs
•Video
•Social Media
•Web traffic logs
"90% of all data ever created, was created in the past two years. From now on, the amount of data in the world will double every two years."

Cloud

4. The Evolution of Big Data
Big data is traditionally referred to as 3Vs (now 5V, 7V)
Volume (amount of data collected – terabytes/exabytes)
Velocity (speed/frequency at which data is collected)
Variety (different types of data collected)
Now experts are adding “veracity, variability, visualization, and value”
Big data is not new
Supercomputers have been collecting scientific/research data for decades
However, now its uses are being seen in commercial competitive advantages
And now we are able to collect a variety of data from multiple devices and sources
Is the evolution of the BI ecosystem from data warehousing
Does not make DW obsolete
Big Data approaches are reducing the costs of data management
Data still needs to be standardized, data quality maintained, and access provided to constituent communities.
Data management will continue to be an evolutionary process.
Big data is simply a new data challenge that requires leveraging existing systems in a different way

5. So, what does Big Data do?
Focuses on finding hidden threads, trends, or patterns which may be invisible to the naked eye
Data store of clusters of servers (eg. Apache Hadoop used for Amazon Cloud)
A set of tasks that processes the data in different segments of the cluster then breaks down the results to more manageable chunks which are
Requires mathematical and statistical expertise as well as creative, communicative, problem-solving, and business skills summarized
Obviates the need for Data alignment or Data migration, or the requirement to move data into one place for cross-referencing. This achieved through indexes and crawlers (like Google) which constantly mine data update the indexes.

6. Framework and Data Flows

Big Data Lifecycle (Management)
•Big Data transformation/staging
•Recording, Storage, Archiving
Big Data Analytics and Tools
•Big Data Applications
•Target use, presentation, visualisation
Big Data Infrastructure (BDI)
•Storage, Compute, (High Performance Computing,) Network
•Sensor network, target/actionable devices
•Big Data Operational support
Big Data Security
•Data security in-rest, in-move, trusted processing environments
Collection and Registration
Filtering, Classification and Enrichment
Analytics, Modelling and Prediction
Presentation and Visualization

7. What challenges can you expect
Platforms
•High end data warehousing tools
•Open source technologies challenging with accessing data from multiple servers rapidly in native form
•Selection of Enterprise Search Tools
Skills
•Managing Data Volumes
•Ability to really understand what can be achieved
•Open source platforms not easy to use
•Data scientists now required
Leadership
•New territory for IT professionals, so planning, marketing, ROI etc is an issue
•Getting Data on the Board's agenda

9. Challenges in Big Data
— Increasing Amount of Disorganized Data and Data Sources (structured & unstructured)
Provides greater opportunity for failure – lack of information can lead to wrong decisions
Limits productivity – more time and effort needed to find information
Frustrates search users –
information is expected to be readily available and complete
