The reverse star schema is a schema optimized for fast retrieval of large quantities of descriptive data. The design was derived from a warehouse star schema, and its adaptation for descriptive data required that certain key characteristics of the classic star schema be "reversed".

The design was derived from a warehouse star schema, and its adaptation for descriptive data required that certain key characteristics of the classic star schema be "reversed".

    Unlike Star schema, the dimensions table in a snowflake schema are normalized. For example, the item dimension table in star schema is normalized and split into two … Hello. From what I have seen, Extended Star Schema is used in SAP BW. Star schema is the simplest style of data mart schema and is the approach most widely used to develop data warehouses and dimensional data marts.

    The dimension tables are not normalized in star schema whereas the tables are normalized in snow flake schema. As the tables are normalized in snow flake schema, it will use less space to store dimension tables and also logically more organized than the star schema. A Schema Selection Framework for Data Warehouse Design M. H. Peyravi International Journal of Machine Learning and Computing, Vol. 2, No. 3, June 2012 222. C. Case 3 If it isn’t possible to normalize the rest of tables, the framework propose star schema. D. Case 4 If there is multi-valued attribute in some dimension tables, i.e. There are multiple values for one attribute corresponding to

    In extended star schema, “fact table” and “master data table” is connected through SID (Surrogate ID) Under the extended star schema model, the dimension table do not BI Extended Star, The BI Extended Star's Advantages Over a Basic Star Schema, Lesson: Creating InfoCubes, Components of an InfoCube (Review). Is a snowflake schema better than a star schema …

    model is similar to the standard flat Star Schema shown in Figure 7, but the hierarchical organization is fundamental to the analysis and the Customer rather than a business activity is the unifying concept.
