Description

Layout procedure (available in the program)

Directed graph with associations (DG)

Directed graphs with associations are used to represent models in which specific object types build a directional structure. These object types can have relationships to other object types.

  • Directed graph (EPC)

  • Directed graph (BPMN)

  • Directed graph (attribute-based)

Central object type (CO)

Models with a central object type serve to represent relationships between this object type and other object types.

Central object type

Central object type with priority (CP)

Models with a central object type with priority serve to represent relationships between the central object type and other object types. Here, the object type with the highest priority in the current model occupies the central role.

Central object type

Pure hierarchy (PH)

Pure hierarchies consist of only one object type. The hierarchy relationship can be reflected by different connection types.

Hierarchy

Hierarchy with associations (HA)

Hierarchies with associations represent trees that consist of only one object type, for example, model of type Function tree. The hierarchy relationship can be reflected by different connection types. Besides hierarchy relationships, other object types can be assigned to the objects that build the hierarchy.

Hierarchy

Hierarchies with crosslinks (HC)

A hierarchy with crosslinks contains multiple structurally relevant object types that can build subhierarchies. These subhierarchies can be linked via structurally irrelevant connections. An example of a model type using this layout is the model type Organizational chart. Objects of the Group and Organizational unit types are structurally relevant and can build subhierarchies using the is superior relationship type. The structurally irrelevant is assigned to connection can be drawn between a group hierarchy and the hierarchy of organizational units.

Hierarchy

SAPĀ® SERM layout

Directed graph with associations, where the direction the relationships are drawn in when created does not match the direction of the model flow. This means that is supertype of relationships between entity type and generalization type, and is subtype of relationships between generalization type and entity type are both drawn from the entity type to the generalization type, while the layout represents relationships from entity type to generalization type, and from generalization type to entity type.

SAPĀ® SERM

Undirected graph (ERM)

An eERM layout requires special handling because the alignment of individual connections does not correspond to the direction the connections are drawn in when created. An example of such a connection is the is subtype of connection drawn from Entity type objects to Generalization type objects. However, the layout will represent the connection as running from the generalization type to the entity type.

ERM

Value-added chain

Combines the properties of a directed graph with associations and the properties of a hierarchy. Directed connections run from left to right, hierarchical relationships from top to bottom.

EPC (column display) layout

EPC (row display) layout

PCD layout

Input/Output diagram layout

This layout procedure is applied to model types that consist of two rows and any number of columns (column display), or vice versa (row display).

Models that consist of any required number of rows and columns use the LAYOUT_IN_OUT layout procedure. Typical examples are the Input/Output diagram or the Business segment matrix.

Models in column/row display

Universal procedure

All model types that cannot be associated with a particular layout procedure are subject to the universal procedure.

UML layout

This layout procedure is used only for UML models edited with ARIS UML Designer.
