Design And Practice Of Order Fullfillment Process With Cross-system Inter Activity For Business Transaction

The background of this thesis is the project of designing and deploying the interaction workflow control of business order for China Telecom Zhejiang branch in order to take over theCDMA system from original China Unicom. At present there being more and more IT support systems built in CTZJ, it's barely expedient for those systems to share information or communicate with other ones by reason of huge differences between construction backgrounds, data models, technical applications and construction manufacturers, which lead to the consequence that only point-to-point interface could be built among those systems. A main feature of those interfaces is exclusive, non-criterion, tight coupling, non-reusable and non-maintainable. It needs to re-construct the interfaces only to waste investment or reinvest when parent system upgrades or the interface itself alters. So under present system pattern and architecture the application integration could not be achieved. After taking over CDMA legacy system, more platforms and systems would be constructed and more interfaces brought out for each platform, therefore it would be a huge burden to later developing and maintenance. This project is actualized to resolve above issue.This project which issues the strategy of actualization and key algorithm, emphasizes on project workflow control and the complexity of the deployment, including the introduction of matching algorithm, data structure design of core memory resident in connection pool, table structure, data structure of memory, ER diagram, sub-module functionality and methodology of exception throwing. Internal and external structure or kinds of classes like IAESRouteCache, CTZJEAISystemException and SyncJMSAdapter are defined thereafter.Meantime the project introduces more methodology, as design and implementation of each functional module, format transformation of target service information, interface adaptor of system functional module, and thoughts of system administration. It also analyzes the design thought of applications, technical architecture of applications, module function and processing workflow in the system.Finally the project offers design and option of test cases, test environment and prerequisite, test assumption and cases, which could analyze the test results and indicate the defectiveness and shortage of the whole system.
