AJAR: Aggregations and Joins over Annotated Relations

Summary: Shows multiway join algorithms plus generalized hypertree decompositions (GHDs) suffice for aggregate-join queries over annotated relations, achieving best-known runtimes. Characterizes equivalent aggregation orders and valid GHDs and decomposes them into unconstrained sub-GHDs to leverage GHD results for tighter bounds, distributed variants, and efficient approximate GHD search.
