What Is Big Data And Why It Is One Of The Most Popular IT Training Course

According to general consensus, Big Data has four V’s that are specific attributes which define Big Data.
These four V’s of Big Data are:

• VOLUME
• VARIETY
• VELOCITY
• VERACITY

Let us see what these four V’s mean now.

VOLUME

The basic characteristic that signifies and makes data “Big” is its sheer volume. There is no sense in focusing on the “minimum storage unit” of Big Data, as the total amount of information that constitutes Big Data is expanding exponentially every year.

According to an annual report published by Thomson Reuters in 2010, it is believed that the world has 800 Exabytes of data, which is growing exponentially by 50% every year.

Although no one knows the exact amount of new data that has been generated every year, however, it can be said that the amount of information that constitutes Big Data is simply gigantic.

If you as a student looking for the best IT Training in Kolkata , and do not know what is an Exabyte, here is the math:

1 Bit= Binary Digit

1024 Gigabytes= 1 Terabyte

1024 Terabytes= 1 Petabyte

1024 Petabytes= 1 Exabyte

1024 Exabytes= 1 Zettabyte

VARIETY

As more and more information is getting digitalized, Variety is one of the most interesting developments in data technology.

Traditionally data types were structured, which means they could fit perfectly in a relational database.

However in the recent years, structured data is augmented with unstructured data, which means anything right from Twitter feeds, to weblogs, and MRI images anything can be captured and stored but it may not have a ‘Meta Model’ that neatly defines the data.

This unstructured data is basically the fundamental concept in Big Data technology, and the best means for understanding unstructured data is to compare it to structured data.

Therefore, the main goal of Big Data technology is to take this unstructured data and make sense of it. 

Now if you are unable to understand structured and unstructured data, let us fetch an example.

Money is will always have numbers, names will have texts, and dates will follow a specific chronological pattern. Hence, these are structured data.

However, pictures, tweets, voice recordings, data which expresses ideas based on human feelings are basically unstructured data that carries information but follow no rules.

VERACITY

Veracity refers to the trustworthiness of the data. Can you rely on the information that the data is representing?

Every student doing IT Training in Kolkata knows that there will always remain inherent discrepancy in all data that are collected and hence must be analyzed.

VELOCITY

Velocity signifies the frequency of the incoming data that is needed to be processed. Streaming data application like Amazon Web Services Kinesis is an example of an app platform that handles the velocity of data that are streaming every minute of every day.

Now, there is also another V of Big Data apart from the ones we talked about, which is known as:

VALUE

Value is the real objective for the development of Big Data technology.

Mashing up the earlier stated four V’s will provide insight, which can be assimilated to create a cross-selling opportunity, a new product line, a cost-cutting measure, or even discover an unknown cause that might result in cure of a disease.

So if you are willing to learn Big Data technology from the best institute for IT Training in Kolkata, your ultimate objective will be to generate value by doing your Big Data analysis, otherwise, you are just performing some technological task for the sake of technology itself.
