Design And Implementation Of WAP Portal System

With the continued socio-economic and cultural development of people's lives are undergoing rapid changes, people are not satisfied with the traditional sitting in front of the computer surfing the Internet brought about browsing information, friends entertainment, send and receive e-mail or other facilities, but hopes to can be anywhere, anytime, no bulky specialized equipment will be entitled to these services. Mobile Internet start followed by the rapid development of user data has also continued to increase. WAP as a bearer data services at this stage the most important way of carrying it out of business will consume most of the mobile Internet bandwidth, as data services in the telecom operators to increase gradually the proportion of revenue, WAP will be the main income support for operators One support service, so a good WAP gateway to the operator's data services is very important. This paper designs and implements a WAP portal.This paper describes the system requirements analysis, general design and system implementation development process.In the system requirements analysis phase, because the system used by the user by the operator's administrator responsible for daily management and maintenance, so this two perspectives of users and administrators to the functionality of the system analyzed. From the user's point of view, the system should provide users with friendly, personalized display page, a simple and intuitive mode of operation and certification authority, business show, business purchase, portals adaptation, ring tones function, I and portals, and other full range of services and operations. From the administrator's point of view, the system should provide administrators an intuitive management interface and standard operating procedures, and page production, business management, rights management, UA group management, log management, data statistics, data distribution, personalization management, management functions.In the system design process, first of all based on user and administrator of the system functional requirements of the system are divided into the portal display subsystem, background management subsystem, content management systems, data analysis subsystem, PDDS distributed data services subsystem and other subsystems.1. Portal front page shows the main control management of the show, such as page layout and composition, the page channel, columns, business presentation, show the number of controls, as well as the gateway to business processes and so on show.2. Portal WAP portal management subsystem to provide the background management functions. Rights management system uses high-precision design, delivery right channel section of the movement and sorting operations, UA packet management, testing services, roaming services such as business, automated extraction, a full range of business data display functions.3. Content Management subsystem is responsible for the content of the new, edit and publishes.4. Data analysis subsystem of the system, all relevant data for statistical analysis and maintenance.5. The portal data distribution subsystem main function is to conduct business data synchronization, Imp's business data will first be synchronized to the portal data distribution sub-system, and then from the portal data distribution sub-system synchronized to each portal.In the system design process, from software engineering point of view, focusing on the system reusability, maintainability and scalability. In the design process to meet the system functions based on the use of a multi-tier architecture, the system layer, said layer, logic control layer, database access layer and database layer. Changes in demand make the maintenance of the system the amount of the minimum. In the design process, also used the method of object-oriented design patterns combined with the system designed to reduce the coupling system, improve the system scalability. Extraction in the system with the versatility of the module design, allows the realization of their business as much as possible degree of loose coupling, thereby enhancing the module's versatility and reusability, and can be customized to meet user requirements. In order to meet the system scalability and flexibility in the system to interface in the form of a large number of pairs of abstract representation of a function, rather than focus on specific implementations, such as: system design and pre-defined statistical interface traffic-per-click system dollars, according to access rate statistics, according to the rate of order statistics implementations, the user would like to others interested in statistical data as long as the realization of this interface can be connected to the system.In the system implementation phase, to follow the system design based on the implementation process in the system continuously exposed design problems had been amended design has been improved enough, not only for the system framework is optimized, but also in the realization of details have also been optimized to improve the system's maintainability and efficiency.System not only provides users with a friendly, customized, personalized theme style, simple, straightforward mode of operation, basically meet the user's business needs and service demand; but also to the backstage managers an efficient, simple, direct System management methods and practical system management tools. The system completed the initial design goals to realize the full functionality.
