💡Feature Idea: Logical Data Modelling Arrowheads
What I want to be able to do: I want to be able to select arrowheads on the relationships which are used for logical data modelling. These arrowheads convey additional crucial information around relationship optionality and cardinality (many-one / many-many).
The ARTS data model (example at https://www.omg.org/retail-depository/arts-odm-73/Logical_02110.jpeg) has great examples of what I am looking for, including:
- three prongs, crossbar and a circle = many / optional
- three prongs, crossbar, no circle = many / required
- no prongs, crossbar, and a circle = one / optional
- no prongs, crossbar, no circle = one / required
Problem I am trying to solve: I am currently unable to create even simple logical data models in Mural solely due to the fact that the relationships are too limited.
Why this helps everyone (or many people): What I am proposing aligns with global standard notation for logical data modelling, and so will benefit anyone worldwide attempting to create such a model. This would elevate Mural's capabilities as a tool for communication and collaboration.
