What is Big data ?

Folks, Do you know where all our computer processed data go? Where all they get stored?

Historically data was accumulated by workers of the company who were entering data into computer systems, then things evolved and then users used to generate their own data and now there is another level of progression where machines are accumulating data. Whole buildings or cities are monitoring the humidity and temperature, power consumption, satellite around the earth who were monitoring the earth 24 hours and taking pictures. Once machines are accumulating data higher than the user. Therefore a colossal amount of data is being generated.

Due to the invention of new technologies, devices, and communication means like social networking sites. The amount of data produced by us from the beginning of time till 2003 was 5 billion gigabytes.

 If you pile up the data in the form of disks it may fill an entire football stadium. The same amount of data was created in every two days in 2011, and in every ten minutes in 2013. This rate of accumulation is still growing vigorously. Though all this information produced is meaningful and can be useful when processed, it is being neglected.

What is Big Data?

Big data means really a huge data, it is a collection of large databases that cannot be processed using traditional computing methods. Big data is not merely a data, rather it has become a complete subject, which involves various tools, methods, and frameworks.

What Comes Under Big Data?

Big data involves the data generated by different devices and applications. Given below are some of the fields that come under the umbrella of Big Data.

·        Black Box Data: It is a component of helicopter, airplanes, and jets, etc. It stores the voices of the flight crew, recordings of microphones and earphones, and the performance information of the aircraft. Basically, every information of the aircraft is stored in the black box.

·        Social Media Data: Social media such as Facebook, Twitter, etc hold information about the views posted by millions of people across the world.

·        Stock Exchange Data: The stock exchange data holds information about the ‘buy’ and ‘sell’ decisions made on a stokes of different companies made by the customers.

·        Power Grid Data: The power grid data holds information consumed by a particular node with respect to a base station.

·        Transport Data: Transport data includes model, capacity, distance and availability of a vehicle.

·        Search Engine Data: Search engines retrieve lots of data from different databases.


Thus Big Data includes huge volume, high velocity, and extensible variety of data. The data in it will be of three types.

·        Structured data: Relational data.

·        Semi-Structured data: XML data.

·        Unstructured data: Word, PDF, Text, Media Logs.

Benefits of Big Data

Big data is really critical to our life and its emerging as one of the most important technologies in the modern world. Follow are just a few benefits which are very much known to all of us:

·        Using the information kept on the social network like Facebook, the marketing agencies are learning about the response to their campaigns, promotions, and other advertising mediums.

·       Using the information in the social media like preferences and product perception of their consumers, product companies, and retail organizations are planning their production.

·        Using the data regarding the previous medical history of patients, hospitals are providing better and quick service.

Big Data Technologies

Big data technologies are important in providing more accurate analysis, which may lead to more concrete decision-making resulting in greater operational efficiencies, cost reductions, and reduced risks for the business.

To harness the power of big data, you would require an infrastructure that can manage and process huge volumes of structured and unstructured data in real-time and can protect data privacy and security.
