Introduction to Big Data

Big Data 

“Big Data is any data that is expensive to manage 
and hard to extract value from.” 


Big Data Now 

“…the necessity of grappling with Big Data, and 

the desirability of unlocking the information hidden 

within it, is now a key theme in all the sciences – 

arguably the key scientific theme of our times.” 

Big Data: Three challenges

• Volume
– the size of the data

• Velocity 
– the latency of data processing relative to
the growing demand for interactivity

• Variety 
– the diversity of sources, formats, quality,
structures
