big data analytics roadmap 2024

What is Big Data?

Big Data refers to vast amounts of information that are too large or complex for traditional methods to handle. It includes diverse data types like text, images, videos is characterized by the three V’s.

1. Volume (large amount of data)
2. Velocity (fast data processing)
3. Variety (different data sources)

Analyzing Big Data provides valuable insights, helping businesses make informed decisions and uncover patterns.

What is Big Data Analytics?

Big Data Analytics is the process of examining massive sets of data to uncover hidden patterns, trends, and insights. It involves using advanced techniques and technologies to analyze large and complex datasets, helping businesses and organizations make informed decisions and gain a deeper understanding of their data.
