@actsasgeek use data sources instead of relation binding

Thanks for the pointer but I’m not sure what you mean. These four relations are the results of previous, simpler queries which I’m trying to tie back together. The only thing I did notice was that I couldn’t use things like or-join without using $. I actually ended up solving the problem a different way by taking the aggregation out of datalog.

oh, cool. I didn’t realize that was possible. Thanks.
