What is Big Data?

Big data involves large volumes of data that traditional data processing tools cannot efficiently process or analyze. It comes from various sources, including sensors for monitoring environmental data, social media interactions, multimedia content, transaction records, and GPS data from smartphones. This exponential increase in data is driven by the widespread adoption of digital technologies, leading to significant challenges and opportunities in data management and analysis. The handling of big data requires specialized technologies and approaches, such as distributed computing frameworks, advanced analytics, and artificial intelligence techniques to extract valuable insights from the data.

Characteristics of Big Data

Big Data is characterized by Six distinct dimensions commonly known as the 6(six) V’s. Each of these characteristics highlights the challenges and opportunities inherent in handling and processing large datasets.

  1. Volume The volume of data refers to the immense amounts of data generated every second. This is the core characteristic that makes data “big.” In our digital age, countless sources produce large volumes of data, including business transactions, social media platforms, digital images and videos, and sensor or IoT data. Organizations must have the capacity to store, process, and analyze this data to extract useful insights.

  2. Velocity Velocity in the context of big data refers to the speed at which data is created, stored, analyzed, and visualized. In the modern business landscape, data is generated in real-time from various sources such as RFID tags, sensors in industrial machinery, and customer interactions on websites. The ability to manage the velocity of data is crucial for real-time decision-making and operational efficiency.

  3. Variety Big data comes in a myriad of formats. This variety includes structured data (like SQL database stores), semi-structured data (like XML or JSON files), and unstructured data (such as text, email, video, and audio). Handling this variety involves accessing, storing, and analyzing data from disparate sources, often requiring specialized tools and methods.

  4. Veracity Veracity refers to the reliability and accuracy of data. High-quality data must be clean, accurate, and credible to be valuable. However, big data often includes noise, biases, and abnormalities, which can compromise the quality of insights derived. Ensuring veracity involves employing advanced data processing and verification techniques to clean and validate data effectively.

  5. Value The fifth V stands for value. It emphasizes the importance of turning big data into actionable insights that create value for the organization. This involves extracting meaningful patterns, trends, and information that can be used to make business decisions, innovate, and maintain competitive advantages. Without extracting value, the other characteristics of big data (volume, velocity, variety, and veracity) are moot.

  6. Variability The final V is Variability in big data refers to the inconsistency and unpredictability in data types, formats, and sources over time. This characteristic poses significant challenges in data integration and analysis, requiring advanced tools and strategies to manage effectively. Strategies like data standardization, utilizing flexible analytics tools, and adopting adaptable data storage solutions, such as data lakes, can help mitigate the effects of variability.

Beyond the six V’s

It’s worth pointing out that big data can often be

  • streamed in real time from data sources such as web logs - this brings very different challenges to data that can be ingested from sources every 24 hours.
  • open data from public data sources, or closed data (proprietary to an organisation).
  • highly unstructured and disorganised.
