What is Data Science?​

Definition:​

Data Science is an interdisciplinary field that focuses on extracting meaningful insights and predictions from large and complex datasets. It combines programming, mathematics, statistics, and domain expertise.

Key Components:​

• Data Collection: Gathering structured, semi-structured, and unstructured data from various sources.
• Data Preparation: Cleaning and organizing data for analysis.
• Machine Learning (ML): Building predictive and prescriptive models using algorithms.
• Big Data Technologies: Handling massive datasets with tools like Hadoop or Spark.
• Visualization: Communicating insights through dashboards, graphs, and reports.

Example Use Case:
A Data Scientist at Netflix develops a machine learning model to recommend movies based on user preferences and viewing history.

What is Data Analytics?​

Definition:​

Data Analytics focuses on analyzing datasets to uncover actionable insights and trends. It typically deals with historical data and answers specific business questions.

Key Components:​

• Descriptive Analytics: Summarizing past data (e.g., sales trends).
• Diagnostic Analytics: Identifying reasons behind patterns or anomalies.
• Visualization: Creating clear reports, dashboards, and charts.
• Querying and Reporting: Using SQL and tools like Tableau or Power BI for business intelligence.

Example Use Case:
A Data Analyst at a retail company identifies which products performed best during a sales period and suggests optimizing inventory.
