Objectives

• Defining Big data and handling the Bigdata

Big data is a term that describes the large volume of data–both structured and unstructured–that inundates a business on a day-to-day basis.But it’s not the amount of data that’s important. It’s what organizations do with the data that matters. Big data can be analyzed for insights that lead to better decisions and strategic business moves

• To get better understanding of what big data is, it is often described using 5 Vs. (many people believe there are 4 Vs, but I think 5 Vs are more appropriate)

• Volume refers to the vast amount of data generated every second.

• Velocity refers to the speed at which new data is generated and the speed at which data moves around.

• Variety refers to the different types of data we can now use

• Veracity refers to messiness or trustworthiness of data.

• There is another V to take into account when looking at big data: Value.
