Multiple object instances on diagrams

Multiple object instances on diagrams

Objects can appear on a diagram multiple times

To do this, users can right click > Duplicate any existing object

The duplicate will be added, along with all of the existing relationships and formatting from the original - a duplicate icon will be added to both symbols

Neither object is the master - they are representationally consistent.

The user can then amend the duplicate object symbol and hide/show a different set of relationships to the first, as they require.

Deleting a relationship will delete it from both instances.

 

Users can also change the appearance of either symbol, independent of each other.

This feature is not yet useable on BPMN or Entity Relationship diagrams - This will be a later phase for the feature

 

 

Permitted relationships when drawing a diagram

Permitted relationships when drawing a diagram

When drawing relationships between concepts, there may be occasions when you are not permitted to draw a line.

          1. No relationship exists in the meta model for two object types

          If there is no relationship type in the meta-model between two object types, then you cannot create a relationship between them.

          2. Directional flows

          Some relationships are directional. That is, if they have an arrow head at the destination, then you are required to draw from the source object to the destination           object.

          If a relationship is bi-directional e.g. associated with, then you can draw from either end.

          3. Diagram Type doesn't support the relationship

          Diagrams are viewpoints on the underlying model. A diagram may represent some object types, and some relationship types between those object types.  This is           typically because a viewpoint is created for different stakeholders who may wish to look at different types of relationships. For example, in ArchiMate, an                     infrastructure usage viewpoint shows infrastructure service with a served by relationship to an application component.  An implementation and                     deployment viewpoint shows application components and infrastructure services but not the served by relationship.

          Our meta-model faithfully reproduces the viewpoints from ArchiMate.  However, we do provide the ability for administrators to modify the view and add all of the                     relationships between object types that are placed on a diagram.

Add Related Objects

Add Related Objects

The Add Related Objects function on diagrams allows you to explore the content of the model in the current client area. It displays a graphical view that shows the relationships between objects, and allows you to quickly slice across the metamodel, focussing in on areas of interest e.g. If an application has an issue, we can see the related processes that may be affected and identify areas where we may see knock-on effects in business services and the ability to deliver/provide products. 

The choices are to populate in a radial fashion around the object, or to populate in a box-in-box format.

Using Add Related Objects function

Radial Layout 

Right click on an object on a diagram and choose Add related objects

A list of objects to Add is pre-populated with any object that has a relationship to the object you right clicked on

Selecting Show Filters will allow users to narrow down the search criteria being used

By default, all relationship types are populated within the search - Users can remove these as they wish

Users can also use smart queries searching to produce very specific criteria e.g. Type = Application component or has a relationship to a business service Z with attribute X set to Y

Once users click the Search button, the list is filtered as they requested

Users can select some or all of the objects within the list and when they select OK, the chosen objects will be added into the diagram in a radial layout.

If users select to add related objects again, the process is additive. If users do not select the Allow Duplicates option, then objects will only be allowed to appear on the diagram once.

Users can then repeat the add related concepts with other objects on the digram, to quickly traverse the metamodel and build a slice across the model

Box-in-Box layout

Right click on an object on a diagram and choose Add related objects

A list of Objects to Add is pre-populated with any object that has a relationship to the object you right clicked on

Selecting Show Filters will allow users to narrow down the search criteria being used

By default, all relationship types are populated within the search - Users can remove these as they wish

Users can also use smart queries searching to produce very specific criteria e.g. Type = Application component or has a relationship to a business service Z with attribute X set to Y

Once users click the Search button, the list is filtered as they requested

When users select the Box in Box checkbox, some more options appear. The options allow the user to

choose how many columns they would like the objects they are adding, added into

If they would like to resize all of the boxes to be the same size as the biggest - to create a uniform display

Users can select some or all of the objects within the list and when they select OK, the chosen objects will be added into the diagram in a box in box layout, within the starting box.

Users can change the layout of a group, by right clicking the group object > Group layout and choosing to resize all shapes in the group, or setting the number of columns

If users select to add related objects again, the process is additive. If users do not select the Allow Duplicates option, then objects will only be allowed to appear on the diagram once.
