Object-oriented programming (OOP) is now widely used in application software development. OOP has advantages connected with handling complexity, reusability, extendability, modularity and data abstraction, enabling it to handle modern programming requirements more effectively than conventional programming methods. Successful advanced manufacturing...

For effective operation, manufacturing information systems must access a number of data sources, including independent computer packages, proprietary database systems and test equipment. Most existing systems are disjointed, or only partially integrated, leading to a number of problems with data access, format, translation and transfer. The solutio...
