import com.allanlxf.ums.entity.SystemUser;

public interface UserDao
{
    public void insert(SystemUser user);

    public void update(SystemUser user);

    public void delete(int id);

    public SystemUser selectById(int id);

    public Collection<SystemUser> select(SystemUser user);

    public Administrator select(String userName, String password);
}
