I don't see what to simplify in markup like this:
@Entity
class User {
@Generated
long id;
@Column
string name;
@ManyToOne
Customer customer;
@ManyToMany
LazyCollection!Role roles;
}
Which translates to table definitions like
CREATE TABLE user (id bigint not null primary key auto_increment,
name varchar(255), customer_fk bigint foreign key references
customer(id));
CREATE TABLE user_roles (user_fk bigint not null foreign key
references user(id), role_fk int not null foreign key references
role(id), primary key(user_fk, role_fk);
...
