|

We now have all the pieces to argue that using our approximation algorithm, the expected multiplicities of a SPJU query can be computed in essentially the same runtime as deterministic query processing for the same query:

\begin{Corollary}
|

Given an SPJU query $Q$ over a \ti $\pxdb$ and let $\db_{max}$ denote the world containing all tuples of $\pxdb$, we can compute a $(1\pm\eps)$-approximation of the expectation for each output tuple with probability at least $1-\delta$ in time
