I want to visualise the data-flow between different database table-columns.
So I tried to connect e.g. column A from entity B with column C from entity D in an ERD.
But it seems not to be possible to connect the two columns directly.
I only need a simple arrow - perhaps with a label - but it should be fixed at the columns if something is moved.
So only draw an arrow over the diagram without an anchorpoint is no solution.
Is there a way to realise that in Visual Paradigm?
