Data Warehousing Questions
A star schema is a type of data model used in data warehousing. It consists of a central fact table surrounded by multiple dimension tables. The fact table contains the measurements or metrics of interest, while the dimension tables provide context and descriptive attributes for the measurements. The relationship between the fact table and dimension tables forms a star-like structure, hence the name "star schema." This design allows for efficient querying and analysis of data in a data warehouse environment.
