Case Study: Design and Implementation of an Ordering system using UML, Formal specification and Java Builder

This paper presents a case study of designing and implementing a sales ordering interactive system using the best practices for requirement analysis and design. We have used UML Use Case, Class, Sequence and State diagrams during requirement analysis and design. Formal methods is used to specify critical requirements and use cases. JBuilder development tool was used to implement the system. In this paper we highlight the best practices for software development and using the latest technology tools enabling us to develop a highly reusable components.
