Find all multivalued dependencies of a relation -


Can anyone explain how to get all the multipurpose dependencies of the following relationships?

Enter image details here

I understand that any FD is also an MVD, so given from that definition Although the FD is a MVD, I have been lost to find all other MVDs

First of all Remove "office" from "employee" by projection.

  • Emp_offices ( name << / strong>)
  • Now the "employees" are in BCNF, and at least emp_offices Is in 5NF.

    Next, "name" - >> "work" is a multi-layered multilevel dependency, and "name" is not a superk in "employee"; Remove "work" from "employee" by launch Employees ( names, projects )

  • emp_offices ( names , office)
  • Emp_tasks ( names, Work )
  • All three of them are at least 5 NF.

    I have an "employee" relationship, because now it is not meant to be with the employees. Emp_projects ( names, projects )

  • emp_offices ( names
  • emp_tasks ( names, Work )
  • If you need an algorithm, the search term "4nf algorithm" is an application here which is essentially here.
