Does Access store two tables which have a one-to-one relationship, as if
they were just one table? I ask because in the db I'm making, there are a
few instances in which a one-to-one relationship seems appropriate. But my
reasoning is that for the same entity, sometimes several fields are relevant
only for some records. So putting those fields into a separate table would
keep the main table from having a lot of empty fields for many records.
But if Access stores the records as if they were in one big table, there's
no point in my splitting the table into two, is there?
This is still the db for the recreational tree climbing business.
Here's an example: tblJobProposals. The fields in this table all apply to
one or two people wanting a climb. If someone wants to arrange a climb for a
group, six more fields apply. So I make tblGroupProposals, with the same
JobProposalID so it's linked to the other JobProposal fields. (Also, of
course, the JobProposalID is a FK in other tables, so I don't want two
different PKs.)
Does it save space and make sense to do it this way? TIA
