Qualifier

An optional second part of a WorkBench definition file record that acts as a subtype to differentiate between multiple records with the same attribute.

Quantity

A component part of a Performance Parameter that contains the formula used to calculate the quantity, and the sets of results calculated for the quantity in any and all Performance Analyses that have been run. Each Performance Parameter normally has just one quantity, called Val, but any number of quantities can be defined, each with its own formula and set of results, to calculate, for example Best Case, Worst Case and Typical Case results for the Performance Parameter.

Query

A query defines a search in the database, retrieving zero or more items of a particular type. A current query is always active as it defines the items shown in the selection list.

Quick Access Bar

The Quick Access Bar provides easy access to the Automatic scope queries for all item types as a scrollable list of controls, each of which provide access to an automatic menu for an item type. The contents of the Quick Access Bar are setup in the Preferences section.
