Star Schema
What is Star Schema?
A star schema is a database organizational structure optimized for use in data warehouses and business intelligence. It features a central "fact" table containing numerical data (measures) and foreign keys to dimensional tables. These dimensional tables describe the factual data with attributes, such as date, product, or location. The star schema is named for its visual resemblance to a star, with the fact table at the center and the dimensional tables radiating outwards. This arrangement simplifies querying and reporting, making it efficient for analyzing large datasets.
