Big Data Problem: Over the last years, a new wave of data emerged which is characterised for being high volume, high frequency, and mostly semi-structured. These data came from multiple sources such as web site logs, web site posts, and machine generated information. But these data contains a lot of hidden information that help the day-to-day business. The need to manage this data resulted in a phenomenon called Big Data. Big data refers to the vast amount of data which cannot be processed and analysed when traditional computer technologies and tools are applied. Big data provides high performance and scalability at a reasonable cost. The main characteristics of big data phenomenon are Volume, Variety and Velocity of data These three characteristics have been defined as the three Vs. Volume refers to the amount of data, variety refers to the number of types of data, and velocity refers to the speed of data processing.

Big Data Problem:

Over the last years, a new wave of data emerged which is characterised for being high volume, high frequency, and mostly semi-structured.

These data came from multiple sources such as web site logs, web site posts, and machine generated information.

But these data contains a lot of hidden information that help the day-to-day business.

The need to manage this data resulted in a phenomenon called Big Data.

Big data refers to the vast amount of data which cannot be processed and analysed when traditional computer technologies and tools are applied.

Big data provides high performance and scalability at a reasonable cost.

The main characteristics of big data phenomenon are Volume, Variety and Velocity of data

These three characteristics have been defined as the three Vs.

Volume refers to the amount of data, variety refers to the number of types of data, and velocity refers to the speed of data processing.
