The Design and Building of Education Website based on Content Management

Abstract. Content Management System is a software system located between web front-end and back-end office system, its basic idea is to separate management and design of content. Page graphic design is stored in the template, and the content is stored in a database or a separate document. When user requests a page, the various parts jointly produce a standard HTML page or are pre-archived into a page when it is issued. The synthetic page may contain multiple data sources. It can fundamentally solve the problem such as bottleneck of technology and the content, role division of the developer and the maintainer, unified and scientific management of the website and so on. Thus the website developer, the system user and the end-user can continually obtain benefits.

Key words:Content Management; Education Website; building

1.Introduction

Along with the development of computer network technology, network teaching has become an important teaching method and the teaching method in the information age. Based on the computer and network teaching, will have the following characteristics: real-time, interactive, broad and so on. The network teaching change the traditional teaching method in the same place and same time, progress of classroom teaching methods, teaching mode of drastic change, teaching content and teaching methods. The network teaching can maximize the use of resources of manpower and material resources to share good education resources, improve the teaching effect.

2.TECHNOLOGY STATUS AND PROBLEMS OF EDUCATION WEBSITE

Course is education website on network infrastructure, is an environmental education and learning programming process. The background is a system programming and database, multimedia data and other content organization program, its prospect is a network interface. On the basis of site function is good program design and implementation; exert the function of the premise and conditions advantage is good web interface. At present, most of the teaching website development professional and technical personnel using the technology background program written to ASP active server pages, PHP, JSP, and so on, and the prospects of development foundation, the union interface HTML graphics (for example, Photoshop), animation (for example, flash), web development tools (for example, the home page, Dreamweaver), etc. This kind of education website exists to the following questions:

In the construction background and foreground page, developers don't usually make a comprehensive arrangement in the page-building, don't form a unified style. In order to uniform interface, they usually copy the code, and modify them to set up new than web pages. This method can cause the system to form an independent module, serious impact on the system scalability, and reduce the flexibility in combination with other applications. If the site needs to modify upgrade, its workload will be enormous.

Content is the soul teaching platform. This is a good question course-education website construction, and on the basis of the system based on the static and dynamic pages the organization of content is boring and update is difficult. Simple content, such as text and images can update problems through the special news system development and activities web technology. However, of course-education website information content is very great, and most of the content is multimedia streaming media. It's too hard, common system problems so much all kinds of information. Therefore, it needs to write the new page when to issue special content; this will seriously affect update efficiency, difficult and then information management in a unified manner.

3. CONTENT MANAGEMENT SYSTEMS

Content management system (CMS short) is a software system the link between webs located at the front (web server) and back-end office system or process (content creation, editor). Content management solutions focused on solving collection, management, use, transfer and added value of the structured or semi-structured digital resources, combined with business intelligence environment containing structured data such as OA, CRM, content of the creator, editors, publishers use submit, modify, approved CMS and publish the content. Content in this is any information resources will be published online, intranets and extranets web sites such as documents, form, pictures, data in the database, video, etc.

The basic idea is to independent content management system management and design content. That's the basic idea to separate CMS content management and design. Graphic design is stored in the page template, content is stored in a database or a single file. When the user request pages, different parts of the common produce a standard HTML page or pre-archived to one page. Synthetic site may contain many data sources. In other words, greatly increasing the content of the web site, don't have to HTML or change the visual effect and the sense of the content of the page doesn't influence. The same content, appear in different space, can upgrade in one place, don't worry, they'll conflict. The result is that once the template is established, even if a user who is no technology can also send self-made page web site, and can promote their own web pages without the help of computer professionals.

A content management system is usually the following content: A: document template; B scripting language or markup language, c, integration and database; Contains the content (control special symbols embedded page. These scores are usually only a CMS. The system is usually language support for complex operation, for example, PHP, ASP, Java, etc.

IBMDB2 is an integrated enterprise content management software solutions, covering management manager, sharing, reuse and file all forms of digital content in an open architecture. To speed up the establishment of content management system, simplify the process of the system change after the establishment of the definition of the XML document and the operation of the system, and get enterprise documents faster, more flexible, IBM plans to XML technology in its content management software in 2004. The upgrade also will enhance the enterprise the network file search and browse document storehouse.

Interwoven6 is one of the most advanced enterprise content management software; it is an enterprise content management solutions, based on XML. Through the application of soap agreement and XML standards, it provides an example of enterprise application integration function level, and put forward the enterprise application more elastic. In response to market needs, speed up the enterprise web site content XML content needs, also launched a random intertwined called to enhance the efficiency of Team XML content author, create the latest, easy to reuse content.

Content management solutions, the promoter of the current Chinese content management, it is committed to the development of the main content management technology infrastructure and application, is committed to be a leading technology and market of China in the field of content management. Content management to solve the current use of XML and Java basic standards, its internal and external data exchange format can XML, XML support when gathering, editing and publishing information. Therefore, import and export of the huge data can use XML standards.

Content management system of system integration is high, the extension is good. Many functions, for example, search engine, calendar, and web mail can be put on the content management system in the form of a module, also can be in content management system integrated form of third party plug-in. This can achieve rapid deployment and flexible expand, ensure that the overall efficiency and flexibility, and lower total cost of ownership. If content management system introduced course-education building site, you can easily expand the function of the page is Manchester united and controllable, soon show a wide range of content, and greatly reduce development costs.

4.BUILDING THE TEACHING WEBSITE OF COMPUTER NETWORK USING CMS

Now has the following three in the management of the content on the website: the traditional static information release, the traditional dynamic information release, static information release based on dynamic information release template, based on the template. In a traditional static information release system, the field staff manually edits the pages, manual to keep files relationship; teaching website, in this paper, the dynamic information release of computer network based on the template.

The website system consists of two parts: the foreground and background. Web site visitors are divided into three kinds of roles: students, teachers and administrators, access is the lowest of the authority students, they only can browse information web site and download of course, assessment course resources, submit assignments route, discusses the knowledge about the course, the teacher can modify teaching material in the line, arrange students to do the experiment, to student's work, to communicate with students online, the administrator shall be responsible for the maintenance of the website. The chart of function and structure about the website is shown in Figure 1.

The prospects of the layout are based on selective template definitions background. These templates can be lonely design and import system, and will they can only influence layout, will not affect its content. Therefore, the teacher can focus on the arrangement and the design content, but don't need to care about the maintenance of the website.

At present, the prospects of the site, including four major parts: professional news, web column, course BBS, etc. Professional news part is used to the latest news and the latest technology in the field of computer network; Course BBS is used to provide a platform, the teacher communication and his students will do. Another committee mainly includes three parts: course evaluation, links and hot vote. The board of directors of the curriculum evaluation statistical platform provides a student, where they can assess the teaching quality of the course. So the teacher can adjust their teaching methods according to statistics situation at any time. The board of director’s friend contact provides some technical website address is related to the course. The board of directors voted with hot current technology is a vote of the view.

The website of the columns of the content on the website main prospect of computer network teaching website, mainly including five parts: course announcement, classroom teaching, professional experiment, work submitted and curriculum resources. The board of directors of course announcement is used to release some information, is related to the course; Board of classroom teaching is primarily used to classroom teaching, and in this BBS have teaching content, teaching calendar and teaching plan, Board of professional experiments are designed to issue arrangement, the content and the deputy data of experiments, and submitted to the board of directors of work mainly for the students provides a way to submit their electronic homework; The board of directors provide software development curriculum resources, technical data, multimedia resources and related courses can help students to expand their knowledge.

The management of the background is the core part in the teaching website of computer network, it includes five modules: management of the templates, management of the site, management of the system, management of the authorities and management of the columns. The part of template management mainly includes the following functions: template manufacture, template registration, template audit, template storage, etc. Because this system has applied the content management technology, the page art design and the curriculum content are saved separately in the different database, so the designer can change visible effect and feeling of the page but does not affect the content. The part of website management implements the registration of the site which will be issued by the system, including the only ID for each site and the issue path of the site; the part of authority management is responsible to assign the different authority to the different content administrative personnel, which can achieve the goal that separate student’s authority from teacher’s and authority administrator’s authority; the part of system management is used to statistic and analyze of the log and automatically backup the contentment of the website; the part of column management is used to maintain the website content, it is responsible for the input, proofreading , audit and issue of the content which will be issued , and it include the management of news, the management of bulletin, the management of teaching plan and the management of experiment. In the information storage aspect, the website system depends on two libraries completely, one is the template library, and the other is the website content database. The template library saves the list of currently available templates which are stored in the format of XML files, and the website content database stores user information, authority information, site information, column information, issue content and log information, etc.

Because the computer network teaching website has applied the content management technology to construct the application system, so the system has the following characteristics:

1)The teacher can maintain his course content at any node of the network, and communicate with his students or other teachers on line.

2)This system adopts safety management mode based on role. Specifically, the users are classified, and the contents which are browsed or managed by the different user can be classified arbitrarily, so the different courses can use the same system, thus reduces the waste of the network resources.

3)The system has adopted a factory method of
