Big data uses statistical inference to determine parameters from a large volume of data

Regressions Nonlinear Relationships Data Dependencies

SOURCES OF DATA TODAY

The Internet

Mobile Devices

Remote Sensing

Software Logs

Cameras

Microphones

Radio Frequency Identification (RFID)

Wireless Sensor Networks

THE CHALLENGESIn the Growth & Digitization of This Global Information

Storage

VOLUME

BIG Volumes The unceasing increase in the amount of data Created everyday Overwhelming in size

VELOCITY

Velocity @ The Speed Of Light… Speed of Data in and out Transactions Business Analysis

VARIETY

Variety Spices up Big Data too

Data Types Data Sources Challenges in

Capture Curate Store

Interpretation Meaningful Analys Search Data Visualization

BIG DATA ROLLOUT

Steps for a mature and meaningful data set Data Profiling Data Cleansing Data Integration of structured and unstructured data Data Merging Data Migration Data Replication ETL / ELT / ETLT Design and Development Interfacing legacy systems with the modern approach

BIG DATA TOOLS

Hadoop, a distributed file system

MapReduce, a framework for data abstractions

Hive for data summarization and adhoc queries

Pig for parallel processing

HBase, a structured storage for large tables

Sqoop for data integration of Hadoop with RDBMS

Flume for data transfers of log data to centralized data repositories

IT IS BIG & IS GETTING BIGGER
