What is Data Science?

Data Science is the process of collecting, cleaning, analyzing, and interpreting structured and unstructured data to extract meaningful insights that help businesses make informed decisions.
In simple words, Data Science answers important business questions like:

• ● Why are customers leaving a product?
• ● Which marketing strategy brings more revenue?
• ● How can inventory waste be reduced?
• ● What will be the future sales trend?

It combines multiple disciplines:

• ● Programming
• ● Statistics
• ● Mathematics
• ● Machine Learning
• ● Business Intelligence
• ● Data Visualization

A Data Scientist does not just write code. They understand business problems and use data to provide solutions.
For example, an e-commerce company may have lakhs of customers. A Data Scientist can analyze their purchase patterns and predict what they are likely to buy next. This directly increases company revenue.
That is the power of Data Science.
