A system design principles 1.1 advanced and mature information technology, especially the rapid development of software technology, new ideas, new systems, new technology introduction Diego phase, which caused a new, advanced technology and mature technology contradiction between. The large-scale, global application system, its functional and performance requirements is comprehensive. Therefore, in the design, technical system, product selection and other aspects of advanced redfin and mature requires unity, in order to meet the system in a very long life cycle of ongoing maintainable and scalable. 1.2 Openness and standards of the system will establish a unified platform for advanced standards in line with national e-government and information about the construction of the relevant standards and will work with some of the existing units of local area network system platform compatible, so that these systems can easily access the into this system. After completion of the system, other systems can access after a certain transformation to the system's platform, so that the e-government platform to become an open platform. 1.3 Effectiveness and sharing system will create intuitive information collection platform and set permissions information release platform. Ensure the effectiveness of government portals redfin and sharing. 1.4 Security Security is the e-government redfin system uptime guarantee, so full attention to the security of the system, including the entire network environment, the basic work platforms, applications and data information system of comprehensive security. 1.5 maneuverability and ease of system construction will be combined with the actual needs, in order to focus on operability, avoiding the pursuit of large. And to ensure the system's ease of use, making all kinds of users (enterprises and workers, approving personnel, the general public) can easily use the system. 2 overall architecture website overall system architecture is shown below: redfin
User layer: external entities connected to the system. User through the browser to access redfin management information system. With interactive redfin features, to fill information, submit the requested operation, the request returns the results displayed in the client. Access redfin control layer: In accordance with user management and access control lists, audit user access to the legitimacy redfin and ensure that systems and information security. User personalization interface control. Presentation layer: the end user friendly interface to provide better quality service to users of the system. Information Access Layer: This layer provides basic Web server used for external static information delivery services, to provide customer redfin backend application server request information and receive the returned information. Application layer: complete the business process logic control and process, a preliminary application security controls and authorization checks, record the original transaction log, store and forward transactions and so on. Provide external application servers, data servers logic functions by running on an application server to complete the various subsystems. For example: directory server to support Lightweight Directory Access Transmission redfin Protocol (LDAP) directory service. Data Access Layer: a unified approach to access back-end data. This layer is a database system redfin for structured information storage and processing data of the system core. Mail server used to provide e-mail support system. System layer: Provides application system platform and runtime environment for hardware system management operations. redfin Hardware layer: Provides the entire system hardware platform. Ensure proper system operation. 5 Construction Method (a) the main government portal site construction, organization information on a variety of topics and enrich government websites, simultaneous construction and management of virtual subnet for the lower levels of government as well as provide a platform for government departments. (2) has not been established website is no longer an independent redfin government department set up public government web sites, portals to establish two sites, and to provide hosting, web hosting, web design, commissioned the development of other items of service. (3) established redfin government websites, in accordance with the specifications and requirements for the portal link. Which have difficulty maintaining websites, application may be made through the government portal provides related services. (4) Construction of the portal in English, Japanese, Korean and other languages, and expand outreach sites, international cooperation for the regional economy, external promotion play the role of a window. (5) to enhance the service function of the government portal, the portal of the government into a public information release platform redfin and a unified online work platform. 6 other planning and design of any website on the internet if you want to provide access, the premise is to connect to the Internet but have a fixed IP, stable and high-speed access lines and bandwidth. The great line access charges, if separately by each department access, will inevitably cause financial and waste of resources. By the municipal construction, maintenance and management of municipal government website management center of government portals redfin using 100M +10 M room high-speed fiber access, you can provide a unified municipal government departments for Internet access services. There are currently hosting (rented), redfin virtual host two access methods. Each host or virtual host has a separate domain name and IP address (or a shared IP address), with a complete Internet server function in the outside world, each virtual host and host really exactly redfin the same, but the cost is quite different, Because multiple virtual hosts to share a real host resources, so each virtual host on the costs are significantly reduced, so that each government department can afford. Government Portal and its subordinate government departments in accordance with relevant provisions of the subsite domain naming a unified planning and management of the domain name.
