In a star schema, dimensions are used to provide context to facts. The CALENDAR dimension likely exists to provide date-related context (such as day, week, month, etc.) for daily visits to the CUSTOM SPA. Since the question specifies a "CUSTOM SPA DAILY VISITS DATABASE," it implies that there is a need to track visits on different dates, suggesting that multiple records (more than one day) would be present in the CALENDAR dimension to accommodate this. However, without specific data from the database, the exact number of records cannot be determined accurately, making this answer speculative based on typical database design principles.
