ITECH2002 Systems Modelling: FBA Subsystem Dynamic Modelling Project

This project provides a detailed analysis of the Fulfillment by Amazon (FBA) subsystem, focusing on two key use cases: registering a product and sales evaluation. It includes extended use case descriptions, activity diagrams, sequence diagrams, and a prototype of the product registration screen. The project also features a test plan for the register product functionality. UML diagrams are used to model the behavior of the system, illustrating the interactions between the FBA reseller and the Amazon system during product registration and sales evaluation. The document is contributed by a student on Desklib, which provides a platform for students to access a wide range of study resources including past papers and solved assignments.
