Question

A colleague and I designed a system for our customer, and in our opinion we created a nice clean design. But I\'m having problems with some coupling we\'ve introduced. I could t

Concerning the first example with the "soluble" property, I have a few remarks:

1. What is "AdministrationRoute" and why would a developer expect to get a medicine's soluble property from it? The two concepts seem entirely unrelated. This means the code does not communicate very well and perhaps the decomposition of classes you already have could be improved. Changing the decomposition could lead you to see other solutions for your problems.
2. Soluble is not a direct member of medicine for a reason. If you find you have to access it directly then perhaps it should be a direct member. If there is an additional abstraction needed, then return that additional abstraction from the medicine (either directly or by proxy or façade). Anything that needs the soluble property can work on the abstraction, and you could use the same abstraction for multiple additional types, such as substrates or vitamins.
