| With the rapid development of computer technology, as well as related technology matures, WEB application has been referred to as the mainstream choice of today's applications. It is a good maintainability of its unique characteristics, so that users would no longer have to install the client program, thus greatly reducing the amount of software maintenance.B / S based on the advanced and less than B / S of Intranet technology, three advantages are substantial: it is a computing technology has been the most stable technology platform. In the C / S era, the user of the most distressing question of how best to choose a stable platform. As the previous technology is based not on the network, so naturally developed a large number of incompatible technology platform. Each technology platform, the stability of demand from the user application perspective, can be said to be short-lived, giving the user left of frustration and anguish. Only access to the network the computer age, as the last 100 million users have been connected to the Internet, and its technology has gained a high degree of stability. It can only development, can not be overthrown, everyone can support, and follow it, control it. It is essentially a client technology, which is particularly suitable for large and medium enterprises. In the C / S mode, the main part of each application is the client side. Other things aside, just the many client-side installation and maintenance of multiple versions of a variety of applications, called people could not take. And the Internet technology is different, the 100 million users only through the unified browser interface, you can enjoy unlimited wealth, and forever changing and developing information services. Intranet in principle, abolished all the client side of the maintenance work. It provides a heterogeneous machine, heterogeneous networks, heterogeneous application services on-line, networking, unified services, the most practical basis for openness. Intranet technology through the unified access heterogeneous databases, have long become a reality. From ISDN to ATM, to the current popular of the TCP / IP, it is precisely because of the popularity of Internet, broadband IP will become a real, unified services (data, voice, multimedia) network infrastructure.News and information release management system is typical of news and information management system, its development include the establishment and maintenance of back-end database and front-end application development aspects. For the former require the establishment of data consistency and integrity of the strong data security and good libraries. For the latter procedure requires the application of full-featured, easy to use and so on.The system uses the mainstream of today's popular technology ASP.NET3.5 + SQL Server 2005 combination. . NET platform since Microsoft has passed since it was launched 10 years, its technology is already very mature and closely integrated and the Windows family of operating systems, compatibility is very high. . NET platform in C # language is Microsoft introduced in 2002. NET platform to the mainstream language, which incorporates C + +, JAVA and other high-level language features, and to be improved. Microsoft SQL Server2005 database is introduced in a large database, its stability and security than SQL Server2000 increased. Coupled with the. NET platform, the perfect integration, is a popular project solutions.The article on the system analysis, system design, system structure, establishment of database design, design of each functional module, a detailed exposition of the system to achieve some of the key technologies in-depth analysis, put forward the corresponding solution. Papers include a few simple parts:The first part is business news and information release management system development background. Through the systematic study at home and abroad related to the feasibility of introducing the system, and gives the project the subject of architecture.The second part as well as the needs of the user survey to determine the system requirements analysis. In this part of the needs of users carried out a detailed investigation, and non-functional requirements are analyzed. Needs analysis is at the top level of software development and demand determines the success of the success of the entire software. Requirements analysis phase gives the user requirements specification, in order to lay the foundation for the design of the next step.The third part is based on the project to determine the needs of a specific time to complete the project, in order to ensure the project team to complete the project on time and shelf-life objectives, the project team members to facilitate a better understanding of the project, thereby making the project work carried out by various rational and orderly process, and to out the schedule.Part IV and Part V is the enterprise news and information release management system design elements, including system architecture design and database design and class design, according to the actual situation of the system selected the development environment: Microsoft Visual Studio2008 integrated development environment, programming language: ASP.NET + C #, Database: Microsoft SQL Server2005. But also the system's user environment and development environment in the system as a whole to consider, namely, at the same time pay attention to external considerations. Software architecture is the basis of practice to build computer software. Software architecture is related to the design level of the following questions: In the calculation of algorithms and data structures, the design and determine the overall structure of the system become a new problem. Structural problems, including the overall organizational structure and global control structure; communications, synchronization and data access protocol; design elements of the function of distribution; physical distribution; design elements of the composition; calibration and performance; alternative design choices. But the architecture is not only the structure, framework also includes the "consistent" system integrity, economic constraints, aesthetic needs and styles. It does not only focus on internal considerations, but also the system's user environment and development environment in the system as a whole to consider, namely, at the same time pay attention to external considerations.Part VI to Part XI of the enterprise management system for news and information release specific implementation and the test is completed. Its number of technical issues involved in doing research and answers. These include all front page designAnd Master Page background to achieve the realization of the system. This part of individual workers can be a concrete realization of the module carried out a detailed argument. Part XI of the system testing phase, the testing phase is based on analysis of the demand requirements analysis specification test whether the system reached a needs analysis is to determine the various functions. The test is complete you can finally deliver the users.12th part of the business news and information release management system for the conclusion of the entire R & D made a summary of ideas and suggest improvements. |
