The Matrix tool allow two types of matrix (aka grid) to be created and edited: an Attribute Matrix and a Relationship Matrix.
An Attribute Matrix is a way of associating properties (attributes and values) to knowledge objects. It does this by presenting a matrix of knowledge objects on the vertical axis and attributes/values on the horizontal axis. A simple clicking operation associates attributes and/or values with the relevant object.
An example of an Attribute Matrix is shown below.
A Relationship Matrix is a way of associating certain knowledge objects (on the X-axis) to certain knowledge objects (on the Y-axis) using a specified relation, such as "followed by", "has constraint" or "requires". One relation per matrix is used. If the relation chosen has properties (attributes and values) then special symbols can be used to show each relationship’s properties. User forms can be designed to aid entry of data, and charts can be created to display the numerical properties of relationships in graphical form.
An example of a Relationship Matrix is shown below. The matrix shows which objects are related to which other objects (using a specified relation).
Another example of a Relationship Matrix is shown below. This matrix shows the numerical values of a relation attribute.
Another example of a Relationship Matrix is shown below. This matrix shows symbols for the ranges of numerical values for a relation attribute.
The user interface of an Attribute Matrix is explained in the following figure.
The user interface of a Relationship Matrix is explained in the following figure.
