Title

Data Separation Model Best Practices

Post

I am finishing up my multi-user app in a single file model.  I'll soon be ready to start the data separation process.  I would love some input on issues and best practices others have experienced.  Here are a few things I've gleaned from the Forum:

1) As long as the user security information is kept in sync, users should only have to logon once to access both files

2) $$ global VARIABLES do not cross the file boundaries.  I should convert all of them to global fields to be safe. True?

3) To separate the code & data, I make 2 copies of the file then change the data source in the relationships graph then clean up

  Question: Is there a way to make the data source dynamic/selectable?  I'd like to be able to use different data sources for different clients.

  Question: Are there best practices around where the relationships are stored (code or data files)? Performance issues with either?

  Question: Do I have to do this all over again when I move everything to a server-based model?

Any other cautions or best practices you'd care to share?

Thanks

Fred
