+        Database engines today use the same approach to evaluate a
+        query as they did forty years ago: convert the query into a query
+        plan, then execute each operator individually, e.g. a join, followed
+        by another join, followed by duplicate elimination.  It turns out that
+        converting a query into binary joins is theoretically suboptimal, and
+        this can lead to poor performance over very large datasets.  A new
+        query evaluation paradigm has emerged recently (some of it coming out
+        of U. of Buffalo), which, in some cases, leads to provably optimal
+        algorithms.  In this talk I will give a brief survey and some new
+        results of this new paradigm: I will review the AGM bound on the query
+        size (Atserias, Grohe and Marx), the worst-case optimal "generic join"
+        algorithm for full conjunctive queries (Ngo, Re, and Rudra), and our
+        new algorithm for aggregate queries, called PANDA, which matches the
+        best known running times for certain graph problems.
