The advantages and uses of Big data will be discussed in depth further in the article.

History of Big Data

In the early days, data collection used to be done manually through handwritten records and filing systems. As technology progressed, computers were used for data storage and processing, but their capacities were limited, and analyzing data took a long time.

In the 1990s, the term “big data” emerged as data volumes exploded. With the advent of the internet, social media, and digital technologies, massive amounts of data became available, requiring new ways to handle and analyze it.

The 5 V’s of Big Data- Characteristics

The 5 V’s of big data, or basically the characteristics of Big Data are the Volume, Velocity, Variety, Veracity and Value of the data.

5 V's of Big data- Characteristics

Volume: Big data involves dealing with a massive amount of low-density, unstructured data, ranging from tens of terabytes to hundreds of petabytes. This data comes from various sources like transactions, IoT devices, videos, images, and social media. Storing and managing such large amounts of data has become easier with affordable storage options like data lakes, Hadoop, and the cloud.

Variety: This data includes different types of data, both structured and unstructured. Traditional data was structured and neatly fit into databases. However, the data includes unstructured data like text documents, emails, videos, audio, and financial transactions. Processing and making sense of these varied data types can require additional preprocessing and support for metadata.

Veracity: Veracity refers to the quality and reliability of data. As big data comes from various sources, ensuring data accuracy, consistency, and trustworthiness becomes challenging. Linking, matching, cleaning, and transforming data across systems is crucial to maintain data integrity. Businesses need to establish ways to connect and correlate relationships within their data to prevent errors and ensure reliable insights.

Value: The value of this data lies in its ability to provide actionable insights and create value for organizations. By analyzing large and diverse datasets, businesses can uncover valuable patterns, trends, and connections. These insights help in making informed decisions, improving operational efficiency, identifying new opportunities, and gaining a competitive edge. Extracting value from this data leads to innovation, growth, and better business outcomes.
