What is big data?

Big data, as the term indicates, relates to massive data sets. Because of their size, diversity, and the fact that they are constantly changing, these data sets have achieved a level of administration beyond the reach of more conventional data management methods. Consequently, the functionality of traditional databases has been overtaken by data warehouse lakes as the go-to solutions for dealing with big data.

Big Data focuses on a specific application of data science where the processing of massive data sets requires the resolution of huge challenges. The fundamental purpose is to optimise the retrieval, storage, extraction, processing, and analysis of data from these huge data sources.

It allows for the identification of patterns and trends and the formulation of decisions on human behaviour and the interaction of technology.

Among the data collections that constitute extremely big data are:

  • Stock market data
  • Social media
  • Events and games related to sports
  • Data gained through scientific studies and research

The banking sector will benefit from Big Data in the following ways.

  • To give their clients individualised banking options that best suit their needs.
  • Improving overall efficiency.
  • Conducting comprehensive analysis of customer feedback
  • Along with having an efficient risk management system.

What are the responsibilities of big data experts?

Dealing with massive amounts of diverse data compiled from a wide range of sources at a faster rate is one of the primary tasks of a big data expert.

Experts in big data outline the structural features of big data solutions and how they can be delivered utilising big data technologies based on the needs.

Are big data and data science the same?

When discussing data science vs big data, we must highlight many significant differences
