Table Iterators and Aggregations in DAX
Table Iterators and Aggregations in DAX represents a formal computational mechanism within database theory where iterators traverse ordered sets to perform scalar or vector-valued operations on rows, while aggregations reduce these results into single summary statistics defined by filter contexts. This concept operates as a fundamental subfield of query language semantics for tabular data models, establishing the mathematical rules that govern how row-by-row calculations interact with context transition and filtering boundaries. It provides the abstract foundation for defining measures through logical set operations rather than procedural execution steps.
