Data analysis systematically examines data to generate insights and identify trends that support business and technical decisions. It depends on well-defined problems, usable data, and disciplined data management. section 1.3 section 1.7
A practical analysis workflow connects several responsibilities:
- Define and scope the business problem before beginning the technical process. section 1.7
- Prepare data through engineering operations such as exporting, transforming, cleaning, and loading. section 1.3
- Check completeness, validity, accuracy, representativeness, availability, consistency, timeliness, and integrity before relying on results. section 1.7
- Use analysis alongside statistics, visualization, business intelligence, data mining, and machine learning rather than treating it as an isolated function. section 1.3
