Enterprise Elements

Relationships

The EDGY language defines three types of relationships each of which can connect source and target elements to express their interplay. This limited number reflects a deliberately simplified model compared to other visual languages used in engineering practice.

Using just three relationships, various Enterprise Elements can be collected and connected in Enterprise Design Boards:

• A Link relationship describes an association between two elements.
• A Flow relationship describes a behaviour or dynamic sequence between two elements, and the passing of structures between them.
• A Tree relationship describes a containment or aggregation between a parent and a child element of the same type.

All relationships are unidirectional, they describe a source and a target endpoint. They can be displayed visually as a line or arrow, but also expressed implicitly through proximity, indentation or alignment on a grid.
