What is Big Data?

What is Big Data?

Definition: Mainly three things define Big Data.

  • The data which is very huge in volume.
  • The data which is constantly growing.
  • The data which is very complicated and difficult to process. The data is so huge and complicated that it is not possible to process it with traditional data management tools.

Some examples of Big Data

  • Population data of any country
  • Stock Exchange data
  • Data is generated by Social Media platforms every day.

Types of Big Data


  • When the data is in a good format, understandable by computers and humans, in proper order, and which can be easily accessed is called Structured data.
    • Here you can see the data is well structure and in a tabular format that can be easily accessed and processed
structured big data example


  • You have Unstructured data when
    • you have different varieties of data types like text, images, video, audio, etc..,
    • your data keeps growing inconsistently, when you face challenges in deriving proper value out of your data,
    • you have issues in processing your data.
    • Examples:
      • In your MSWord document, you write texts, embed images, videos, links, etc.… If any system is fetching this data and processing it, it is very difficult to bifurcate and process that data.
      • Weather forecast reports
      • Traffic data
      • Military movements


  • This is a kind of structured data that neither follows a tabular format to represent the data nor they follow the relational database structure. But still, they contain some tags or markers to identify the structure and representation of the data.
    • Examples:
      • XML, Other markup languages
      • Emails
      • JSON

In Azure, we have some services that can be of great help in processing Big Data.

For this chapter, we will focus on key areas only. For individual service explanations, you can refer to Microsoft or service documentation.
