DATA MODEL

Hello, 

I have 4 facts table and have this model as follows:

  Table 1                                     

  Key Index

     - Emp No

     - Hire Date

     - Termination Date

Table 2

Key Index

   - Emp No

   - Date

Table 3

Key Index

   - Emp No

   - Date

Table 3

Key Index

   - Emp No

   - Date

Calendar

  - Date

below is the diagram for easy understanding.

My question is how can i link table 2 [date] , table 3 [date]  and table 4 [date]  to calendar[date] keeping star schema model.   

Or is there a way to do measure keeping table 1 related to calendar and not table 2,3 and 4?

Thanks for your help.

Regards,
