Could be the same thing. Objects that contain just data have no behavior. You might also be referring to J2EE design patterns: DAO and Value List Handlers.

The term "Value Objects Pattern" was accidentally re-coined by the blueprints folks. It was already being used! The proper term is "Data Transfer Objects Pattern" although when some folks implement it, they use stuff like "EmployeeDTO" which I think is klunky and cryptic. I prefer saying "EmployeeData"
