Big data is a essential ability and challenge that requires creative ways to gather, analyze, and form conclusions from data larger than what can be handled by traditional data processing tools. Big data is a key component of technology developments for multiple industries and opening up possibilities for creativity, innovation, and decision-making.

In this article we will learn in detail what is big data, its meaning, definition, characteristics of big data, and types of big data along with it’s challenges. Let’s begin.

What Is Big Data

In simple words big data meaning refers to really large sets of information that are too big and complex for traditional methods to handle effectively. Big data includes a variety of data types, from numbers and text to pictures and videos, and comes in quickly from sources like social media, sensors, and online activities.

The international conference IEEE Big data 2023 focused on privacy and security research issues in the context of Big Data, an active and demanding research environment that is at the center of the Database research community. It was concluded that these issues are fundamental to this research context.

Now let’s have a look at the different characteristics of big data.

Characteristics Of Big Data

The characteristics of big data include several key attributes, commonly known as the “Vs.” These characteristics are important for understanding the nature of Big Data. These characteristics of big data are –

Volume

Example – Google processes over 3.5 billion searches per day, leading to an annual estimate of around 1.28 trillion searches which is a really big data.

Velocity

Data is flowing continuously in large quantities. This defines the data’s potential, or how quickly the data can be created and processed to satisfy needs.

Example – Facebook’s user base is increasing by approximately 22% year by year. As of the latest available data, Facebook had around 2.8 billion monthly active users, reflecting the rapid pace of user growth.

Variety

One of the main characteristics of big data is Variety. It includes different types of data, including structured data (e.g., databases), semi-structured data (e.g., XML, JSON), and unstructured data (e.g., text, images, videos). Managing and analyzing this variety of data requires flexible and adaptable processing methods.

Example -YouTube has over 500 hours of video content uploaded every minute. This immense variety includes videos in different formats, resolutions, and content types.

Veracity

Focuses on the correctness and dependability of the data. Big Data sources may contain inconsistencies, errors, or noise, making it crucial to ensure the quality of the information for meaningful analysis.

Example – Google’s search algorithms are designed to filter through and prioritize accurate information from the vast volume of web pages indexed.

Value

Value is one of the important characteristics of big data. It focuses on the goal of extracting meaningful insights and value from the data. The primary purpose of dealing with big data is to get information that can lead to improved decision-making and strategic advantages.

Example – Facebook’s advertising revenue amounted to approximately $84.2 billion in the most recent fiscal year. The value derived from targeted advertising based on user data contributes significantly to the company’s revenue.

Variability

Variability refers to those characteristics of big data that represents the dynamic nature of data flow. Big Data sources show changes in volume, velocity, and variety over time, requiring flexible processing methods.

Example – Twitter experiences variability in data flow, especially during major events. The platform sees a rise in tweets and user interactions during such events, requiring adaptable processing methods to handle the fluctuating data volume.

Visibility

Being one of the characteristics of big data, variability refers to the strong nature of data sources, requiring adaptability in processing methods to handle changes in volume and type over time.

Example – Google Maps uses Big Data to provide visibility into real-time traffic conditions. By analyzing data from smartphones and other sources, Google Maps helps users navigate efficiently by avoiding busy routes.

Volatility

Characteristics of big data include the capture of the temporary nature of certain data. Some data in big data environments may have a short validity or relevance, which requires organizations to adapt quickly to changes in the data landscape.

Example – Financial markets generate vast amounts of data in real-time. Stock prices, currency exchange rates, and commodity prices can be highly volatile.

Moving on from the different characteristics of big data, let’s discuss the types of big data.

Types Of Big Data

The characteristics of big data based on their structure and organization, play an important role in forming how businesses extract value from this amount of information. Big Data is classified into different types based on this structure and organization of information. The different kinds of big data include –

Structured Data

  • Structured data is highly organized and formatted information that sticks to a specific pattern or data model.
  • From the types of big data structured data is most noticeable in our everyday life.
  • It is typically tabular and fits neatly into relational databases, allowing for easy inquiry and analysis.
  • By generating a single record to represent an entity, it is divided across several tables to improve the data’s integrity. Table constraints are applied to apply relationships.
  • Structured data has a clear plan and pre-planned data types.
  • It is easy to search and accessible.
  • Structured data is commonly used in traditional databases like SQL.
  • Example – A structured data example is a monthly budget, expenses like rent, utilities, groceries, and entertainment.

Unstructured Data

  • Unstructured data lacks a predefined data model and doesn’t follow traditional databases.
  • It is flexible in terms of content and format, making it difficult to analyze using traditional methods.
  • Unstructured data has no fixed structure or pattern.
  • It has different formats such as text, images, audio, and video.
  • Requires advanced analytics for meaningful insights.
  • Example – Social media posts, multimedia files, and text documents where information is not organized in a standardized way.

Semi-Structured Data

  • Semi-structured data falls between structured and unstructured data. While it has some organizational properties, it doesn’t strictly stick to the pattern of relational databases.
  • These types of big data do not have a strict structure that controls the management or storage of the data. Like a spreadsheet, where the data is neatly arranged into rows and columns, Semi-structured data is not stored in a relational format.
  • Semi-structured data is also referred to as NoSQL data as it doesn’t require a structured query language.
  • These types of big data can be exchanged across systems with different basic structures by using a data serialization language.
  • It has a hierarchical structure with flexibility.
  • May have tags or markers for organization.
  • It is suited for NoSQL databases.
  • The most common formats for semi-structured data include JSON (JavaScript Object Notation), XML (eXtensible Markup Language), Zip files, YAML (YAML Ain’t Markup Language).
  • Example – JSON or XML files used in web development, where data has a defined structure but allows for some variability.
