Big data means it is a gigantic measure of data sets that can’t be analysed, processed, or stored utilising traditional tools.

Today, there are a huge number of types of big data sources that produce data at a quick rate. These data sources are available across the world. The absolute biggest wellsprings of data are social media networks and platforms. We should utilise Facebook as an illustration. It creates an excess of 500 terabytes of data consistently. This data incorporates messages, videos, pictures, and so on. The 3 “V”s of big data are Volume, Velocity, and Variety.

  1. Structured Data
  2. Unstructured Data
  3. Semi-Structured Data
  4. Subtypes of Data
  5. Interacting with Data Through Programming

1. Structured Data

Any data that can be processed, accessed and stored as a fixed-format is named structured data. Throughout some period, ability in software engineering has made more noteworthy progress in creating techniques for working with such sort of data and inferring an incentive out of it. Notwithstanding, these days, we are anticipating issues when the size of such data develops to an enormous degree, average sizes are being in the fury of various zettabytes.

Structured data in big data is the most straightforward to work with. Structured data is a types of big data that profoundly coordinated with measurements described by setting parameters.

It’s all your quantitative data: 

  1. Address
  2. Debit/credit card numbers
  3. Age
  4. Expenses
  5. Contact
  6. Billing
  • Structured Data Examples:

An ‘Employee’ table in a database is a Structured Data Examples.

Employee_IDEmployee_NameGenderDepartmentSalary_In_ Lacs
1865Meg LanningFemaleHR6,30,000
2145Virat KohliMaleFinance6,30,000
4500Ellyse PerryFemaleHR4,00,000
5475Alyssa HealyFemaleHR4,00,000
6570Rohit SharmaMaleFinance5,30,000

2. Unstructured Data

This is one of the types of big data where the data format of the relative multitude of unstructured files, for example, image files, audio files, log files, and video files, are incorporated. Any data which has an unfamiliar structure or model is arranged as unstructured data. Since the size is huge, unstructured data in big data has different difficulties as far as preparing for determining a value out of it.

An illustration of this is an intricate data source that contains a mix of images, videos, and text files. A few associations have a ton of data accessible with them. However, these associations don’t know how to infer an incentive out of it since the data is in its raw form.

  • Unstructured Data Examples:

The output returned by ‘Yahoo Search.’

  • The differences between structured and unstructured data in big data are:
  1. Qualitative vs Quantitative Data
  2. Defined vs Undefined Data
  3. Ease of Analysis
  4. Predefined Format vs Variety of Formats
  5. Storage in Data Houses vs Data Lakes

3. Semi-Structured Data

Semi-structured data is one of the types of big data related to the data containing both the formats referenced over, that is, unstructured and structured data. To be exact, it alludes to the data that, even though it has not been ordered under a specific database, yet contains essential tags or information that isolate singular components inside the data. Along these lines, we arrive at the finish of types of big data.

  • Semi-structured data Examples:

Personal data stored in an XML file.

4. Subtypes of Data

In spite of the fact that not officially viewed as big data, there are subtypes of data that hold some degree of relevance to the field of analytics. Frequently, these allude to the beginning of the data, for example, social media, machine, geospatial or event-triggered. These subtypes can likewise allude to get to levels: linked, lost/dark or open.

5. Interacting with Data Through Programming

Diverse programming languages will get various things done when working with the data. There are three significant players available: 

  1. Scala: On the come up in fame is Scala, a Java based-language. It was utilised to build up a few Apache items, including Spark, a significant part of the big data stages market.
  2. R: For more modern examination and explicit structure, R is the language of decision. It is one of the top coding languages accessible for data control and can be utilised at each progression of an investigation cycle completely through to perception.
  3. Python: It is an open-source language and is viewed as one of the least complexes to learn. It uses compact abstraction and syntax.
  • Big data examples:
  1. Predictive inventory ordering.
  2. Personalised marketing.
  3. Streamlined media streaming.
  4. Personalized health plans for cancer patients.
  5. Live road mapping for autonomous vehicles.
  • How big data works:

The fundamental thought behind big data is that the more you think about anything, the more you can acquire experiences and settle on a choice or discover an answer. Along these lines, you need to realise how big data works and the three fundamental activities behind it:

  1. Integration
  2. Management
  3. Analysis


The classification of big data is divided into three parts, such as Structured Data, Unstructured Data, and Semi-Structured Data.

Big data makes ready for essentially any understanding a venture could be searching for, be the analytics predictive, diagnostic, descriptive or prescriptive. The domain of big data analytics is based on the shoulders of monsters: the capability of data analysing and harvesting down has been known for quite a long time, if not hundreds of years.
