I never enjoyed working with relational data bases, but one thing I
learned is that it pays to keep your data in a normalized form
(i.e. not repeat common information for every service, but put
transponders and services in two distinct "tables" and have the
service reference the transponder).

The downside of the relational model is that you then need unique
transponder IDs. The upside is that once you have those IDs you
can use them throughout the system.

E.g. the samba style format proposed by

([source] ... [mux] ... [service]) had a nice data model, but the
mux-IDs were manually assigned names, not something a scan tool
would produce.
