Data Warehousing Questions
A data warehouse schema bridge dimension is a type of dimension that is used to bridge two or more different hierarchies within a data warehouse. It acts as a connector between these hierarchies, allowing users to navigate and analyze data across multiple dimensions. The bridge dimension typically contains attributes that are common to the hierarchies it connects, enabling users to drill down or roll up data seamlessly. It helps in providing a comprehensive view of the data and facilitates efficient data analysis and reporting in a data warehouse environment.
