  • Basic data types include text, numbers (integers and floating points), and booleans.
• Big Data:
  • The challenges of storing large volumes of data and the need for specialized systems.
  • Importance of understanding data types and their impact on functionality.
• Data Collection Methods:
  • Active vs. passive sampling: intentional data collection vs. automatic gathering.
  • Relevance, accuracy, validity, and reliability of data are critical for effective operations.
• Data Presentation:
  • Various methods to present data, including graphs, infographics, dashboards, and reports.
  • Importance of structured vs. unstructured data and feedback mechanisms.
• Data Errors and Bias:
  • Identifying and addressing errors in data collection to avoid incorrect information.
  • Understanding bias in data sources and the need for diverse data collection.
• Blockchain Technology:
  • Use of blockchain for tracking data movement, ownership, and applications in online voting and identity verification.
• Privacy and Security:
  • Importance of security measures for data protection and understanding terms of agreements.
  • Ethical considerations regarding data ownership and privacy.
• Data Storage Solutions:
  • Different storage options: local storage, cloud storage, and data warehouses for historical analysis.
• Data Quality:
  • Ensuring data is correct, reliable, and meaningful for enterprise operations.
  • Ethical implications and permissions surrounding data access.
• Processing and Presenting Data:
  • Transforming raw data into understandable information for stakeholders.
  • Use of relational databases, SQL for querying, and Machine Learning for data interpretation.
