What is Big data?

Accessing and storing a large amount of information for analysis has been practiced for many years. However, the concept of big data spread in the early 2000s, when industry analyst Lane clarified the current basic definition of big data. Organizations collect data

from a variety of sources, including business transactions, smart devices (IoT), industrial equipment, video and social networks. Storage was a problem in the past, but using cheap storage on platforms like data lake and Hadoop can ease the burden.

With the growth of the Internet, data must flow to businesses

at an unprecedented rate and be processed in a timely manner. RFID tags, sensors and smart meters have increased the need to process these large amounts of data in near real time.data is provided in all types of formats, from numerical data structured in traditional databases to unstructured text documents, email, video, audio, stock quotes and financial transactions
