schedule join multiple tables
Basically I need an scalable efficient way to select all scheduled items so it made sense that the main table is the schedule. The problem is that all the operation tables have different properties
I created a diagram which is obviously wrong but demonstrates what I am trying to achieve. I was thinking about having the join on the other side so that all three operations pointed to the schedule, but if I do that then to get a complete schedule I have to aggregate all the operation tables. What if I have loads more in the future?
