- We have discussed the potential problems…with leaving a many to many relationship…in your database solution.…Again, FileMaker allows many to many relationships,…so why do we wanna avoid them?…To review, the issues that we mentioned…in the actor in movie's many to many relationship were,…that we wanted to create a report that list all the actors,…their roles, salary, and total salary…for all the roles they've ever played,…but we didn't have a context or table…to be able to based that off of.…And also, we ran into issues with storing character names…and salaries for each role because again,…no table exists for a role.…
Then also, how do we manage…actors working in different numbers of movies?…One actor might be working on 10 movies…and another working on five,…and then those lists can constantly grow,…so if we define a field…for each one of those roles for the actors,…we would never know how many different fields we would need.…We also discussed the searching issues…that we run into in our database.…How would we find an actor that played a certain role…
The course applies to versions of FileMaker Pro from 7 through the most current version.
