Many-to-one relationship

Consider a many-to-one relationship where many employees belong to a single department. You can use code like the following to define a many-to-one mapping between the Department and Employee objects. 

public class Employee 
    { 
        [Id] 
        var id:uint; 
        [ManyToOne(targetEntity="Department",fetchType="EAGER(default)|LAZY")] 
        [JoinColumn(name="deptId",referencedColumnName="DEPT_ID")] 
        var dept:Department; 
    }

The default fetchType value is EAGER. See Lazy loading and fetch type for information on fetch types
