Each association can be configured as one-way association as well as bi-directional association.
If you wish to define association as Has One and Belongs To at the same time, draw just one line and define details on the Association properties modal form.

Each type of association is graphically represented in the diagram by a silghtly different line.

  • Has one/Has many - solid line.
  • Belongs to/Belongs to many - dashed line.
  • Both - dash-dotted line
