Hi, yes and no!
With @Basic(optional=true) the persistence provider checks if a field is nullable or not. For example if false is selected you will get an error by the persitence provider if you forget to set a field. The @Column(nullable=true) is an information that the persistence provider uses when he creates physical database objects. It's up to you to select if the persistence provider and/or the database should check this. Hope that helps you!
