Research And Implement Of State Coal Mine Security Production System Based On Design Pattern

Along with the rapid development of electron, communication and computer technology, the government organizations use modern information and communication technology to integrate management and service by Internet technology, and building electronic governmental affair system becomes an important mean of construct harmonious society. With the continual development of Web 2.0 technology, B/S structure becomes first selection of developing web application system depending on B/S structure's easy to deploy and other merits. J2EE technologies have become the standard platform of building enterprise level application system, which are becoming mature gradually.From ninth decade of last century, data structure and algorithm does not become big problems of large common software design. Designing a well reusable and expandable software architecture is becoming hot issue of software engineering area. The Gof (Gang of Four) put forward 23 classic design patterns . This provides abstract theories and excellent solutions for large software design. Also the system building theory of this paper is based on these design patterns.At first, this paper first introduces the background, significance and technology of building state security production information system. Sequentially, the paper introduces the related knowledge of design pattern and then focus on summarizing the core thinking of design pattern. In the meantime, the paper introduces the micro-architecture theory. Then it discusses the macro architecture and design thinking of the state security production information system. It concentrates on explaining the design scheme of every tier of the system architecture and the application of design pattern for every tier.Finally, the paper describes the business capabilities, figures out the business architecture of our system. Then it brings forward system development model, explains concrete implement of each tier of the development model in detail. Next, it takes report selection business module of the system for example, places emphasis on discussing how to apply micro-architecture theory of design pattern for designing three concrete business units of the report selection framework which contain report selection process, internet user logon and company code creation. Next, the paper discusses the concrete implement of report selection module, report show module, security licence manage module and company information manage module in detail.
