Default multiple back-ends

If you haven't gotten a response yet covering your question about PKs and
FKs, here's some thoughts...

If you are saying that each of your (3 or 4) databases have "core" tables,
and those cores are the same topics, but the data in each "core" table is
different, from app to app, then yes, you have a potential issue in
connecting the core records with their respective child table records.

For example, if all dbs have a core tblPerson table, but App1 has John Doe
as PersonID=1, while App2 has Bill Smith as PersonID=1, and so on, then you
clearly cannot expect the non-core tables that point to tblPerson to have
the correct foreign keys (most of the time).

I guess I'm having trouble visualizing what you mean by "the activity tables
have the core tables PKs as FKs". Is that the same as saying that the
activity tables are your "child" tables?

More info, please...

Hi,
I have 3 or 4 databases developed separarely over the past couple of years
covering different areas of company activities - project monitoring,
support
call monitoring, QHSE monitoring etc. The company has grown and I'm
looking
to consolidate and distribute these. I'd intended to split them into
FE/BE
so that the just the appropriate FEs could be installed on any user's PC
and
the back-ends would reside on the server. I'd thought at first that I
could
have a "core" BE with e.g. a staff and client table and activity specific
BEs. But the activity tables have the core tables PKs as FKs. Does this
mean I have to put all the tables into 1 BE? or am I missing something?
