Study Notes
Business Intelligence and Data Analysis
- Data Warehouse is a dynamic read/write system, always online, collecting detailed data for transactional purposes.
- Data Mart, a read-only static data system, collects synthetic data for analytical purposes and can be an offline "snapshot" of a DB.
- OLAP, part of Business Intelligence, involves analyzing entities from various perspectives through sorting, filtering, grouping, and calculating.
- OLAP analysis involves values (measures) and elements (dimensions) resulting in a structure called Info Cube, with basic operations like roll-up, drill-down, and slicing.
- Dashboarding, the third step of Business Intelligence, represents meaningful patterns in a highly readable, interactive, and exportable format.
- Data Visualization in Business Intelligence focuses on the graphical representation of data to extract understandable information from it.
- New business software provides future predictions using Analytics instead of Data Analysis, requiring Data Mining and business understanding to extrapolate future data.
- Data Mining is a set of techniques for automatically finding meaningful patterns in data using advanced statistical methods.
