Data Warehouse Introduction (VII)-Star model and snowflake model

 Multidimensional data modeling organizes data in an intuitive way and supports high-performance data access. Each multidimensional data model is represented by multiple multidimensional data patterns, and each multidimensional data pattern consists of a fact table and a set of dimension tables. The most common form of multidimensional models is the star pattern. In star mode, the fact table is centered, and multiple dimension tables are radiated in their four weeks and connected to the fact
