Working with a CRUD matrix

Chapter 4 Building Business Process Diagrams

Working with a CRUD matrix

You open the CRUD Matrix from the Resource CRUD Matrix or Data CRUD Matrix commands available from the Tools menu.

The matrix shows the relationships between all processes and data (or resources) of the current model or package. You must have at least one process and a resource or a data object in order to have access to the commands.

The resource must be linked to the process or the data must be assigned to the process in order to see the CRUD values in the matrix.

For more information about how to specify data for a process, see Process property sheet Data tab.

The following tools are available in a CRUD matrix window:

Tool	Description
	Properties – Opens the property sheet of a: Process, if you select a row header. Resource or data, if you select a column header. Resource flow or data, if you select a cell. If parallel resource flows exist between a process and a resource, you will be prompted to choose the resource flow whose properties you want to consult.
	Copy – Copies a CRUD matrix in order to paste it into another application such as: Excel (as CSV). Word (as text).
	Find Symbol in Diagram – Finds in the diagram the symbol of a: Process, if you select a row header. Resource, if you select a column header. Resource flow or process that contains the CRUD values, if you select a cell. If parallel resource flows exist between a process and a resource, you will be prompted to choose the resource flow, whose symbol you want to find in the diagram.
	Select Rows/Columns – Opens a selection box listing all the available objects, which allows you to add or remove rows and columns.
	Display Only Full Rows/Columns – Displays only objects sharing a relationship or shows all available objects.

You can reorder the rows in the matrix by using the arrows at the bottom of the process column.

Modifying CRUD values

You can modify the matrix CRUD values by selecting a cell and then selecting or deselecting check boxes in the Current Cell Value groupbox at the bottom part of the matrix window.

You cannot multi-select cells to modify their CRUD values.

Changes automatically display in the diagram for the resource flow when required. The CRUD values in the Access Mode groupbox of the resource flow property sheet or in the Data tab of the process property sheet change accordingly.

Note that the matrix does not let you add a CRUD value to objects that are not already related in some way in the diagram.

Moving from cell to cell
You can move from a cell to another using the Arrow keys of your keyboard.
