The technical terms used throughout Valsight, covering model building, workspace visualization, scenario management and dimension management.

## A

**Add comparison**\
***Workspace***\
A chart option that creates comparisons across a selected dimension (for example, years or scenarios) for the selected visualization.
See [Comparisons](/scenario-time-or-dimension-level-comparison-delta/).

**Aggregation**\
***Model***\
Summarizing data across levels (for example, Month → Year). The levels used determine how values are combined, and the behavior can be controlled per node.\
See [Aggregation Settings](/aggregation-settings/).

**Aggregation settings**\
***Model***\
Node settings that define how aggregation behaves for display and for calculation. Display aggregation affects workspace visuals, while calculation aggregation affects model results.\
See [Aggregation Settings](/aggregation-settings/).

How values from different inputs are matched before a calculation is applied. Alignment is primarily driven by shared dimensions and levels.\
See [Formula basics](/formula-basics/).
