Big Data in Retail: A Revolution [Use Cases and Examples]

The retail industry is an ever-changing landscape. How do big data and retail combine? The global big data analytics in retail market size was valued at $4,854 million in 2020 and is projected to reach $25,560 million by 2028. This shows us the importance of big data in retail. 

In this article, we will dive deep into the world of big data in retail. Let’s see: 

What is Big Data?

Big data refers to extremely large and complex datasets that cannot be easily managed, processed, or analyzed using traditional data processing tools. These datasets are characterized by the three Vs:

  • Volume: Big data involves large amounts of data. This could be in terms of terabytes, petabytes, or even exabytes of information.
  • Velocity: Data is generated at a high speed and must be processed quickly. For example, social media posts, sensor data, and online transactions are generated rapidly and require real-time or near-real-time processing.
  • Variety: Big data comes in various formats and types, including structured data (like databases), unstructured data (such as text, images, and videos), and semi-structured data (like XML files). The diversity of data sources adds complexity to the analysis.

Use of Big Data in the Retail Industry 

Big data has become increasingly valuable in the retail industry, offering a range of applications and benefits.

 Here are some key ways in which big data is used in the retail sector:
