Associate multiple date columns in a fact table to a date dimension table

Using aliases for date columns in a dimension table to associate them with specific date columns in a fact table is not the recommended approach. It can lead to confusion and make the data model less intuitive and maintainable. It's advisable to establish proper relationships between the fact table and the date dimension table using appropriate keys or foreign key relationships for each date column. This ensures data integrity and allows for easier analysis and reporting.
