Question
What is the primary difference between Big Data and
traditional data ?Solution
The defining characteristics of Big Data are often referred to as the 3 Vs : Volume , Velocity , and Variety . These attributes distinguish Big Data from traditional data: • Volume refers to the sheer amount of data generated, often in petabytes or exabytes, compared to the more manageable size of traditional data. • Velocity represents the speed at which data is generated and needs to be processed, with Big Data coming from real-time streams (like social media or sensors). • Variety describes the different forms of data, including structured (e.g., databases), semi-structured (e.g., JSON, XML), and unstructured (e.g., videos, text), making Big Data more diverse than traditional data, which is typically more structured. Option A (Big data is easier to process and analyze than traditional data) is incorrect because Big Data requires specialized tools and techniques due to its complexity and size. Option B (Big data typically comes in unstructured formats, while traditional data is always structured) is partially true but oversimplifies the distinction. Big Data includes both structured and unstructured data. Option C (Big data is generally smaller in volume but more complex than traditional data) is incorrect because Big Data is typically much larger in volume. Option D (Traditional data requires advanced tools and techniques for analysis, whereas Big data can be analyzed using basic statistical methods) is incorrect because Big Data requires advanced tools, like Hadoop and Spark, to process and analyze due to its scale.
