What Is Data Science?
Data science is a combination of various fields of study like mathematics and statistics, computer programming, data analytics, AI, and Machine learning, which help provide potential insights into an organization’s data.
Four primary stages of data science are:
- Collection of both the raw structured and the unstructured data from reliable sources using tons of different ways. It is the first step and is known as data ingestion.
- Next, a team has to handle the storage of the ingested data. The company requires efficient and secure storage systems. During this phase, the ingested data is stored and processed.
- A team of data science professionals then analyze the raw data through the various patterns, ranges, and distributions and conclude by reporting the insights they gather.
- Communication of the data is done finally by creating visualizations, generally created using programming languages like R or Python.
