- To generate reports from all kinds of data
- To perform a market analysis to help businesses to grow to beat their competitors
The following are the different fields of data analytics:
As per the field, nature of the date, tools, techniques, applications, source of data, and many more, there are many different fields of data analytics. Some of them are given below:

Data engineers set up the infrastructure to move forward for companies with increased traffic. They are also responsible for the constant analysis of data. It is pertinent to know about machine learning and heavy statistics for becoming data engineers. They are also known as Data Scientists and Data engineers in some places.
3. Machine Learning Engineer:
Machine learning engineer is for companies where data is their main product. Mostly consumer-facing companies use the services of machine learning engineers.
4. Data Science Generalist:
As the field suggests, it is a generalized job to fill in the shoes of any responsibility lacking in the data team. Data science generalist has many hats from touch production code analyst, analysis in-charge, data visualization work, and many more.
