Data Warehousing Questions
A data warehouse schema star join is a type of join operation used in data warehousing that involves joining a fact table with multiple dimension tables in a star schema. In this schema, the fact table is at the center and is connected to the dimension tables through foreign key relationships. The star join is performed by matching the primary key of the dimension tables with the foreign key in the fact table, allowing for efficient retrieval of data for analysis and reporting purposes.
