The Filter Revisor Pattern in Power BI
The Filter Revisor Pattern represents a formal computational mechanism within data analysis theory wherein logical filter operators dynamically re-evaluate and adjust active context without altering the underlying physical storage or structural schema. This concept is defined by the abstract principle of virtual column modification, distinguishing it from materialized changes in relational algebra by operating strictly on evaluation contexts rather than row-level persistence. It serves as a specialized subfield of query optimization and context transition logic within broader information retrieval systems.
