POAbstract Base class for All Domain Entity Objects
text
Body
copied!<p>I am seeing in some domain object models that an abstract base class is created(that implement Equals and GetHashCode) for all domain Entity objects to inherit from to gain their identity.</p> <p>I am not clear why this base class is needed and when and why it should be used. Can you provide me some insight on this or refer me a link that talks on this</p> <p>Thanks</p> <p>Now I understand the advantages of overriding Equality (this link helped <a href="http://en.csharp-online.net/CSharp_Canonical_Forms" rel="nofollow noreferrer">http://en.csharp-online.net/CSharp_Canonical_Forms</a>—Identity_Equality)</p> <p>Going back to domain driven design I would like to expand my question a bit;</p> <p>I have a customer entity which I use guid as identity.</p> <p>If I create 2 instances of customer with exactly the same details, since I am using guid as the identity they will be two different objects. But as they have all attributes the same they should be the same object(or is it a better ddd practice to keep them unique and seperate??)</p> <p>Trying to understand if I should handle the equality of two objects by their full attribute value match. If I go toward that direction then I am looking at either overriding the Equality of the base class on the level of sub class and implement these conditions or have the identity of the entity a string or hash code(?) representation of the values of all these attributes and use the Equality of the base class.</p> <p>I could be little off here so thanks in advance for the patience.</p>
