Using “X” in cell matrices
“X”-in-cell matrices indicate whether or not a relationship exists between two definitions. The existence of a relationship is indicated by X in the cell that intersects two definitions: “X” indicates a relationship exists; a blank indicates no relationship exists.
The result of a cross-reference can have the following implications:
Each row definition may store a list of the column definitions.
Each column definition may store a list of the row definitions.
Note If each Row definition stores a list of Column definitions, and each Column definition stores a list of Row definitions then the intersection information is duplicated. Because of this, you will typically see that the “related definition” properties in both definitions are read-only.
Sample "X"-in-Cell matrix: Role to Competency
To open the role to competency matrix
1 With the Samples encyclopedia open in System Architect, select View > Matrix Browser.
The Matrix Browser appears.
2 On the Organization tab, open the Role to Competency matrix by double-clicking the name (or right-click the name, and select Open).
3 Click Next to bypass the Matrix Filters dialog.
4 Click Finish to bypass the Matrix Filters dialog (leaving the default -- all column and row definitions selected). The Role to Competency matrix is presented.
