In case anyone has done this before, I'd appreciate any tips for optimizing a link analysis application , e.g in its simplest form if we have one or more tables of the form A B =================== a1 b1 a2 b1 a3 b2 a1 b4 a4 b1 a5 b3 a6 b2 b1 b3 b3 a2 ....
are there any tips for optimizing queries of the type: 1) for each ai find all bjs connected to it and for each of them figuring in the 'A' collumn find bm's connected to them ,i.e. a1->([b1->b3, b4) a2->(b1->b3) etc 2) same, except that this will be done on selected ai matching other criteria and not all entries. Any tips for optimization?(I assume this should not be done with pure sql statements).
