Re: [libreoffice-users] Multiple select field in Base forms

Hi :)
Oh, i thought that in the manual boxes each piece of music would have 3 cards, one in each box.  

One problem being that some pieces only had a card in one or 2 of the boxes.  It might be 
frustrating trying to find where the holes are in the data.  Moving to a database solves that as 
each piece of music would only have 1 card but could be viewed in each of the 3 different orderings 
quite easily and missing data would be easier to spot and fix.  

Regards from
Tom :)

If I understand your application is to cross reference for example a musical piece by 
instrumentation required, vocal parts required, liturgical season (Advent, Lent, Easter, etc.), 
possibly service setting (Holy Communion, Matins,  Vespers, etc.).

I would see a main table with listing each work with a unique id number assigned to it (key). The 
issue is how many tables will actually be needed for a good database design. Each table will have 
its own key with any foreign keys listed for cross referencing. The basic design rule is to enter 
data once and the keys establish the relation between the tables.

For a first pass at the design I would look at the data and cross referencing used in your manual 
card catalogue for data relationships.
