This lesson is part of AWS · All levels
Summary
Data analytics is the process of turning raw data into actionable insights. AWS groups data into structured (table), semi-structured (JSON), and unstructured (image/video). Data lakes store all the raw data on a large scale, while data warehouses optimize analytic queries on the structured data that has been curated.
Key points
- Three types of data: structured, semi-structured, and unstructured
- OLTP for daily transactions, OLAP for analytics
- Data lake: flexible storage of raw data (usually in S3)
- Data warehouse: quick query on structured, curated data
- The four levels of analysis: descriptive, diagnostic, predictive, prescriptive
