Users may also select alternative definitions of class cohesion. One alternative is Hitz and Montazeri's 1996 redefinition of Li and Henry's graph theoretical calculation.

For each symbol in the database, Imagix 4D collects a number of attributes. These attributes are specific to the type of symbol they describe. Unless otherwise noted, the attribute data is collected and updated by analyzing your source code.
