Data Analytics Definition

Data analytics is the process of collecting, analyzing, and interpreting data to find patterns, trends, and relationships between them. It is a multidisciplinary field that uses tools and techniques from mathematics, statistics, and computer science.

Data analytics can include

  • Data analysis: Working with data to glean useful information
  • Data science: High-level analysis
  • Data engineering: Creating the frameworks needed to store data
  • Data mining: Extracting usable data from a large dataset
  • Data modeling: Diagramming data flows
  • Data visualization: Presenting data in a clear picture using visuals like bar graphs, pie charts, and tables

Note that Data analytics can help:

  • Improve decision-making
  • Gain a deeper understanding of their processes and services
  • Identify new opportunities
  • Build related digital products
  • Create personalized customer experiences
  • Harness cost savings
  • Optimize operations
  • Increase employee productivity
