11. Data Science and Big Data
How to Use This Section
Use Data Science and Big Data as a guided sequence, not a folder of isolated notes. Start with the foundation pages, pause after each major topic to make your own example, and keep a list of confusing terms to revisit.
Suggested Learning Path
Build Understanding
- First pass: skim the child pages and mark the topics that feel unfamiliar.
- Second pass: study Introduction to Data Science, Data Preprocessing and Cleaning, Data Visualization Techniques, Big Data Tools and Technologies and write a one-line summary for each.
- Practice pass: create one example, case, diagram, or dry run for every major concept.
- Revision pass: compare related pages and ask what changes when assumptions, facts, inputs, or constraints change.
