Equivalence of Relational Algebra and Relational Calculus Query Languages Having Aggregate Functions
Open accessAbstract
Aggregate functtons m relattonal query languages allow intricate reports to be written.In this paper aggregate functions are precisely defined The definition does not use the notion of "duphcates."gelattonal algebra and relattonal calculus are extended m a general and natural fashton to include aggregate functions It is shown that the languages so extended have eqmvalent expressive power Categories and Subject Descriptors.H 2 3 [

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
