How have we come up with these statistics?

How do we know that these are true?

How have we estimated these numbers?


All these questions lead us to BIG DATA ANALYSIS.

What is Big Data Analysis?


Every day, we create 2.5 quintillion bytes of data – so much, that 90% of data in the world today has been created in the last two years alone.

Big Data Analysis is the process of examining large and varied data sets. It is the art of exploring data.

The concept of big data has been around for years; most organizations now understand that if they capture all the data that streams into their businesses, they can apply analytics and get significant value from it. But even in the 1950s, decades before anyone uttered the term "big data," businesses depended on basic analytics to uncover insights and trends.

Importance of Big Data

Big data analytics helps organizations organize their data and use it to identify new opportunities. That, in turn, leads to smarter business moves, more efficient operations, higher profits and happier customers. Big data enables :

Cost efficiency: Some tools of Big Data like Hadoop and Cloud-Based Analytics can bring cost advantages to business when large amounts of data are to be stored. They help in cutting down expenses. By this, we can save data without using much of the money resources.

Time Efficiency: The high speed of tools like Hadoop and in-memory analytics can easily identify new sources of data which helps businesses analyzing data immediately and make quick decisions based on the learnings.

Developing a New Product: By knowing the trends of customer needs and satisfaction through analytics you can create products according to the wants of customers. This increase the chances of creating a product that will be used by the mass.

Understand the market: By analyzing big data you can get a better understanding of current market conditions. For example, by analyzing customers' purchasing behaviors, a company can find out the products that are sold the most and produce products according to this trend. By this, it can get ahead of its opponents.

Control online reputation: Big data tools can do sentiment analysis. Therefore, you can get feedback about who is saying what about your company. With the feedback, you can make necessary changes thereby increasing the reputation of the company.


Once we know what big data is and how it helps us in all aspects, one might ask, how can I analyze my data?
