Just for clarity, I assume there's two approaches I can take here: 1. n+1 lookup, where I get all type2 related to type3 and for each type2 do a lookupresource to get type1. 2. At a small scale, I assume I can do two complete readrelationships (type2 and type3) and correlate them in memory. Just wondering if there's a third I'm missing or if those are my options.
