As part of building my ???????? ??????????? ?????? project, I learned about ????? ??????? in Domain-Driven Design and how EF Core uses the OwnsOne() method to handle them in the database context.
???? ??? ????? ????????
Value Objects represent a concept with ?? ???????? but ?????????? ???????? based on their data. They are often used to model things like Score, Money, or Email in a domain.
???????:
public sealed class ReviewScore
{
public int Value { get; }
private ReviewScore(int value) => Value = value;
}
??? ??? ???????()?
In EF Core, OwnsOne() tells the framework that a property (like a value object) is ????? ?? ??? ?????? ?????? and doesn't have its own identity table. This simplifies the data model and keeps domain integrity.
?? ?? ??? ???????() ???? ??? ????? ????????
Typically yes, OwnsOne() is meant for ????? ??????? and ??????? ????? that are fully dependent on the parent entity.
??? ???? ??? ???? ???????() ?? ????? ??????? ?? ???? ????????, ??? ???? ???????? ???? ?????? ???? ??? ????
