Data Science is the the field involved with one of the following tasks:
Extraction, gathering, or collecting data and structuring it.
Manipulation of raw data to prepare it for analysis, or use in machine learning tasks.
Extracting of knowledge, meaning, and insights from data using statistical and computational methods and visualizing it for predictions and inform decision-making tasks.
Components:
Data Strategy: Long term process for handling data science tasks, including methodology, data, assets management, etc.
Data Engineering: Designing and building systems for data gathering and Machine Learning training processes.
Data Analysis: Finding patterns and anomalies using statistical methods and machine learning algorithms.
Data Visualization: Presenting data and it's analysis results in a visual manner using graphs and charts.
