Conceptual Modeling of Data Warehouses
{"Image DocumentName": "Conceptual Modeling of Data Warehouses", "Image ImageDescription": "Modeling data warehouses: dimensions & measures. Star schema: A fact table in the middle connected to a set of dimension tables. Snowflake schema: A refinement of star schema where some dimensional hierarchy is normalized into a set of smaller dimension tables, forming a shape similar to snowflake. Fact constellations: Multiple fact tables share dimension tables, viewed as a collection of stars, therefore called galaxy schema or fact constellation.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
