The Trade Order System Design And Development

The more popular the using of internet is, the higher qualities for the web application of the investment banks are required, especially for the huge investment banks. Based on an outsourced big financial project from a well-known foreign investment bank, this thesis will explore how to design and establish a variety of design documents, thus avoiding the usual large-scale software projects failing or delaying which often happens in the other projects. And this thesis also gives a solution to howt to design and build a Single Source application module which is based on the user’s specific requirements. The following is a list of main content:1. Exploring how to design and UML modeling on a software project, and how to create Logical Archetecture Specification, Business Component Design Specification, User’s Requirement Specification, and all sorts of design diagrams, such as Logical Archtecture Diagram, Component Interaction Diagram, User Case Diagram, Data Flow Diagram, Sequence Diagram, Activity Diagram, Class Diagram, etc. And also the Database Domain design diagrams.2. Based on the user’s specific requirements for single code set for multiple locations, this thesis explores how to achieve a solution to solve this situation, which includes throughout details technical solution of configuration, coding, build and deployment.3. From the user’s specific requirements for Single Sign On, this thesis explores how to implement a fully self-designed solution for this requirement, which includes how to design and build an application of self-designed Single Sign On, and moreover, this thesis also gives a solution to automatically change the encryption keys which are used in Single Sign On module, and the changing of encryption keys has no impact to the user’s login function.
