Tableau joins operate on a relational database principle where logical tables formed by combining physical data sources preserve integrity based on defined join keys and join types (Inner, Left, Right, Full). The mechanism dictates that the resulting Logical Layer dataset includes all matching rows from both input tables according to the selected algorithmic rule, while non-matching records are either excluded or represented as NULL values depending on the specific theoretical constraints of Inner vs. Outer operations. This concept is foundational within Data Warehousing and BI analytics for constructing single analytical units (logical models) that unify disparate attributes without immediately merging physical storage layers.
