Hi,
List all the employees in a listview and add a button (View Skills) inside the listview to open a page which has a datagrid which list the skills of specific employee in a new page via association. Silmilarly,you can use this to retrieve skills of specific jobs
Here is the domainmodel:
Now in the Domain model view, right-click and select Generate Overview pages. Select all three entities and you've got _Overview and _NewEdit pages. In the _NewEdit pages of both Employee and Job, add a Datagrid with as Datasource the association to Skill.
