Cardinality’s official, non-database dictionary definition is mathematical: the number of values in a set. When applied to databases, the meaning is a bit different: it’sthe number of distinct values in a table column relative to the number of rows in the table. Repeated values in the c...
To describe this distribution, we first have to deal with the problem that it is not immediately obvious how to cleanly parameterise the space of partitions, given that the cardinality of the partition can be finite or infinite, that multiplicity is allowed, and that we would like to identify...

During optimization and initial compilation, this feature propagates cardinality estimates that are based on actual table variable row counts. This accurate row count information optimizes downstream plan operations. See Table variable deferred compilation. Approximate query processing with APPROX_COUNT_...
Each cardinality (drawn as aconnecting lineon the diagram) has a small symbol that reflects these numerical values. The symbols change based on how much data moves between them. Share the diagram with your team When the final database design is finished, you can share the diagram with the ...
