What is Big Data?

Before going through what Big Data is, let us have a look at some powerful stats.

What do you notice from the stats mentioned above? It is that Big Data is everywhere, in every industry, and is only going to grow, opening doors of opportunities for a bright career in Big Data. This has brought a surge in the candidates opting for a career as a Big Data Engineer.

What is Big Data?

Big Data is a term that describes huge volumes of data that includes structured and unstructured data. Big Data inundated a business on a daily basis. The data is so huge that it is termed “Big Data” and is so large, fast, and complex that it is impossible to process it using traditional methods.

One thing to be noted is that it is not the amount of data that is important, but the thing that matters is how and what organizations do with the data. Typically, Big Data is analyzed to gain meaningful insights that lead to better business decisions and strategic moves.

The mainstream definition of Big Data, articulated by the industry analyst Doug Laney in 2000, is the three V’s.

Volume: Organizations gather data from different sources, including smart IoT devices, business transactions, videos, social media, industrial equipment, and many more. Traditionally, it would have been challenging to store this data, but proper storage on platforms like Hadoop and data lakes has made the storage easy.

Velocity: With the exceptional growth in IoT devices, data enters into businesses at an incredible speed and must be handled conveniently. Sensors, smart meters, and RFID tags(Radio Frequency Identification) drive the requirement of dealing with these torrents of data in close real-time.

Variety: Data occurs in all types of formats- from numeric, structured, in traditional databases to unstructured text documents, videos, audios, emails, stock ticker data, and financial transactions.

The two additional dimensions that are described these days are variability and veracity. The flow of data is unpredictable and is varying greatly. Veracity is all about the quality of data. Since data comes from a variety of sources, it’s difficult to cleanse and transform the data across systems.

Different frameworks like Spark, Cassandra, Hadoop, and Apache Storm are used to overcome the challenges that come across processing Big Data. With the help of these frameworks, a Big Data Engineer can handle all of this Big Data. Let us now explore what a Big Data Engineer is and how to become one.
