http://www.bigdataschool.ca Big Data Consultant
“Big Data is the frontier of a firm's ability to
store, process, and access (SPA) all the data it
needs to operate effectively, make decisions,
reduce risks, and serve customers.”
--Forrester

“

“Big Data in general is defined as high volume,
velocity and variety information assets that

http://www.bigdataschool.ca Big Data Consultant
“Big data is data that exceeds the processing
capacity of conventional database systems.
The data is too big, moves too fast, or doesn't
fit the strictures of your database
architectures. To gain value from this data, you
must choose an alternative way to process it.”
--O’Reilly
