Design And Implementation Of Trouble Ticket System

In terms of the investigation of requirement for real fault processing business in radio and television’s operation and maintenance management departments, this dissertation systematically analyze and summarize the original fault business process, and proposes trouble ticket system based on a three-tier architecture of J2EE. In this architecture, the trouble tickets system is divided into three-tier:presentation layer, business layer and persistence layer. Using object-oriented technology, combined with the fault maintenance scenario, the domain model is designed in business layer, which could decompose the business logic to different domain objects. Therefore, this design is not only beneficial to improve the system’s high cohesion and low coupling, but also greatly enhance the software’s reusability, maintainability and scalability.In this thesis, firstly, it discusses J2EE framework and Object-Oriented technology, and also analyzes the features of the MVC pattern. Secondly, through in-depth study of SSH framework, Struts, Spring and Hibernate framework, this paper proposed a new design on the basis of a classic J2EE architecture, namely through three framework technologies integrated system architecture to achieve good effect. Thirdly, taking trouble ticket system for example, this proposal takes advantage of this solution to analysis and design the architecture, and accomplish an implementation of system functional module; Finally it should be verified by system test.In this thesis, trouble ticket system mainly consists of three parts: user management, trouble ticket management, and alarm experience library management.User management mainly includes the login module and the modification of the user status information.Trouble ticket management module is the core module of the whole system, introduces payment, feedback and audit of the trouble ticket.Alarm experience library management includes the management of fault processing experience.Overall, there is a requirement analysis which is based on the discussion of the project background and the work flow in the third chapter, and there is also a system architecture design and implementation explanation in the fourth chapter, and there is also a system test and validation in the fifth chapter. There is a summary for the work done in the final chapter which proposes an improvement for the system.The trouble ticket system has been implemented according to schedule and run successfully. The practice proves that the trouble ticket system based on J2EE architecture design is not only fully meet the actual needs of users, but also greatly improves the efficiency of software development.
