you can achieve this by using the idea of inheritance how?
public abstract class ADDRESS
{
public ADDRESS()
{
this.ADDRESS_ID = Guid.NewGuid();
}
public Guid ADDRESS_ID { get; set; }
public string ADDRESS_LINE { get; set; }
public string CITY { get; set; }
public Guid? STATE_ID { get; set; }
public string ZIP { get; set; }
}
public parital class OCCUPATION_ADDRESS: ADDRESS,IValidatableObject
{
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
if(string.IsNullOrWhiteSpace(ADDRESS_LINE))
yield return new ValidationResult("Address line is required!",new string[]{"ADDRESS_LINE"});
}
}
public parital class WORK_LOCATION_ADDRESS: ADDRESS,IValidatableObject
{
public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
}
}
// and your Occupation details class will be like: instead of ADDRESS you will use the corresponding derived classes
public class OCCUPATION_DETAILS
{
public string COMPANY_NAME { get; set; }
public string JOB_TITLE { get; set; }
etc...
public Guid OCCUPATION_ADDRESS_ID { get; set; }
public virtual OCCUPATION_ADDRESS OCCUPATION_ADDRESS { get; set; }
public WORK_LOCATION_ID { get; set; }
public virtual WORK_LOCATION_ADDRESS WORK_LOCATION_ADDRESS { get; set; }
}
and the inheritance should be Table per Hierarchy (TPH)
for more information about TPH check this Table per hierarchy
hope that this will help you
