from the development trunk to the M5XQ branch
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2009/06/12 - tsheyar: compiler/include/logical_mnemonic.h,1.42
-- Replaced aggregate operators count, min, max, avg, sum, prod, seqty1,
and all in the algebra by a single aggregate operator ``aggr''
that can handle multiple aggregates. The aggregate entries
are of kind count, min, max, avg, sum, prod, seqty1, all, and dist.
-- Added new aggregate kind ``dist'' that allows to represent group by
columns that functionally depend on the partitioning criterion
in the result of the grouping aggregate.
-- Added rewrite that merges aggregates.
-- Added rewrite that removes superfluous aggregates.
-- Added rewrite that pushes a rank operator through an aggregate.
-- Extended the XML import to cope with the old
as well as the new representation of aggregates.
