Answer

Brief Explanations:

  • Web Scrapers: Tools like Beautiful Soup (Python - based) or Scrapy. They extract data from websites. For example, they can gather product details from e - commerce sites.
  • APIs (Application Programming Interfaces): Twitter API, for instance. It allows developers to access Twitter's data (tweets, user information). Data is collected as per the API's rules and endpoints.
  • Database Management Systems (DBMS) with ETL (Extract, Transform, Load) Tools: A DBMS like MySQL combined with ETL tools (e.g., Apache NiFi). Data from different sources (databases, files) is extracted, transformed (cleaned, formatted) and loaded into a data warehouse. For example, customer data from various transactional databases can be aggregated.

Answer:

  • Web Scrapers: Extract data from websites (e.g., product details from e - commerce sites).
  • APIs: Access data from platforms (e.g., Twitter API for tweet and user data).
  • Database Management Systems with ETL Tools: Aggregate data from multiple sources (e.g., customer data from transactional databases).
