Generating process tree diagrams
Data flow diagrams of a process model only represent the data flow
among processes of the same level. To display hierarchical links among
processes, i.e. to show their decomposition ModelSphere offers to
generate and display a tree diagram.
To generate a process tree expand the Explorer tree and select the root
diagram. Right-click, and choose the Generate->Tree Diagram menu
item. A dialog then appears giving the following options:
Span : normal or
minimized
“Minimized” will generate a more
compact tree which could
have an impact on the transparency.
Orientation :
horizontal or vertical
“Horizontal”
displays process
hierarchy in rows “top down”
“Vertical”
displays the process
hierarchy in columns from the
left to the right.
Alignment : left or
center
“Left” aligns all
process rows to the left margin,
“Center” aligns
all process rows in the center.
When “Vertical”
alignment is set, the alignment options are changed to “top or
center”.
Fit
Processes :
Instead
of having all the process
of the same size, this option
allows to fit the size of each process to.
Display
only
exploded processes :
Leaf nodes are
not displayed in
the generated tree diagram.
Once a tree diagram is generated, it is not possible to add processes,
actors, stores or flows. (The tool bar is active, but trying to add new
model elements will be refused.)
A tree diagram is linked with its original diagram (see the Parent
Diagram field in the design panel), so modifications of its processes
will be displayed instantaneously, but if you change the parent diagram
by adding new subprocesses, the tree diagram is not updated
automatically. To update the tree diagram select the Tree Diagram
in the explorer, and choose Generate->Process Tree.
