Mapping a partially populated DTO to a domain object?

One way is to pass the list of properties changed to the Update Service. This can be as simple as having an integer where each bit indicating some property OR array of property indices or names etc. You can also make your DTO's self tracking in a sense that each DTO will maintain what properties have been changed.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
