| Today, the information systems have become increasingly complex, multiplex and interactional. The traditional function-oriented methods of development cannot fit in with the complexity and inconstant requirements, and the result of analysis and design cannot be reused effectively. By comparison, object-oriented modeling technique is flexible, reusable and can reduce the risk of development because it makes the complexity and changeability in control. So object-oriented technique can improve the effectivity of software development. And Unified Modeling Language is a standard language for specifying, visualizing, constructing, and documenting the artifacts of object-oriented software systems. So the transformation from function-oriented method to object-oriented methods is inevitable.In this dissertation, I have discussed the object-oriented modeling technique including several famous object-oriented methods, the Unified Modeling Language and the development process based on the Unified Modeling Language, and have applied these technologies to model the complex information system-Cashier Operation Transactor System. I believe that it will be significative to object-oriented modeling of information systems. |
