An Abstract Description Method of Map-Reduce-Merge Using Haskell

Algorithm 16

lTablet1 = fromList [((2, “A”), 0), ((3, “A”), 250), ((1, “B”), 150)]   –Tablet1 of Table1

lTablet2 = fromList [((4, “B”), 0), ((7, “C”), 200), ((6, “D”), 100)]  –Tablet2 of Table1

lTablet3= fromList [((5, “A”), 300), ((8, “C”), 150), ((9, “D”), 0)]     – Tablet3 of Table1

lTable = [lTablet1, lTablet2, lTablet3]            –Table1

rTablet1 = fromList [(“A”, 0.95), (“B”, 1.15)]         –Tablet1 of Table2

rTablet2 = fromList [(“C”, 1.00), (“D”, 1.25)]          –Tablet2 of Table2

rTable = [rTablet1, rTablet2]                –Table2
