| Aug 8, 2014 at 5:26 | comment | added | user22815 | I have had good success with putting as many fields as make sense on the object itself, and using arbitrary properties for whatever the customer comes up with on their own. It is not ideal, but requires less code maintenance. | |

| Apr 18, 2014 at 12:51 | comment | added | Tony | Not sure what language you are using, but if it is C# you could use a dynamic type which basically stores a KVP in a dictionary kinda like what you are doing on products and allows you to just tack on properties without having to directly add them to the collection as a collection. You will not have strong typing though. I know you asked for a design pattern but I don't feel you would need anything complex to use them. msdn.microsoft.com/en-us/magazine/gg598922.aspx | |
