I am working on using QGIS to enter borehole data using QGIS Relations. It is a snap to create 1:1 and 1:N relations on one foreign key, but it is impossible to work with composite keys (such as the relationship between SAMPLE_DATA and SOILS_INDICES_LAB in the relations.jpg).

  • Target version set to Future Release - Nice to have

This was taken into account when designing the low-level implementation of the relations functionality. However, the GUI for it and probably some logic as well is missing (obviously).
I plan to do continue working on this in the future.
If you are interested in funding to raise the priority of this issue, please contact me via PM.

We are interested in funding this issue. Unfortunately we have to limit ourselves to a developer from the US because we are a California state agency.
