(1) ASP can break through some functional limitations of static web pages and realize dynamic web page technology;
(2)ASP files are contained in files composed of HTML codes, which are easy to modify and test;
(3) The ASP interpreter on the server will make ASP programs on the server and send the results to the client browser in HTML format, so that all browsers can browse the pages generated by ASP normally;
(4)ASP provides some built-in objects, which can make server-side scripts more powerful. For example, you can get the information submitted by users through HTML forms from the web browser, process the information in the script, and then send the information to the web browser;
(5)ASP can use server-side ActiveX components to perform various tasks, such as accessing databases, discovering and accessing e-mails or file systems.
(6) Because the server sends the result of ASP program execution back to the client browser in HTML format, users will not see the original program code written by ASP, which can prevent the ASP program code from being stolen.
Edit the working principle of ASP in this section.
When ASP functions are integrated into a website, the following happens:
1. The user enters the URL in the browser address bar, and the default page extension is. asp。
2. The browser sends a request to the server.
3. The server engine starts to run ASP program.
4.ASP files are processed from top to bottom, script commands are executed, and HTML page contents are executed.
5. Send the page information to the browser.
Edit the running environment of ASP in this section.
Asp needs to run under PWS or IIS. PWS or IIS service is attached to the CD of windows98 or windows2000, and can be installed through Add/Remove windows Components in Add/Remove Programs.
Generally, asp should be combined with access database or SQL Server database to compile powerful programs.
Web server software capable of running ASP
Windows2000 installs IIS 5.0 by default, windows xp installs IIS5. 1 by default, and windows 2003 installs IIS6.0 by default.
PWS (Personal web Server) is a simple personal web server running in windows98 environment.
Edit the meaning and characteristics of this ASP.
ASP (Application Service Provider) refers to "an operator who provides application software services by lease through the network", that is, the operator takes application software as the main body and delivers services one-to-many through the network. This service-oriented trading model enables enterprises to have more cost-effective software use rights through leasing, and can also greatly reduce the maintenance cost of enterprises because of the centralized management of operators.
Basically, ASP has three characteristics: software service, service networking, the combination of information outsourcing service and network, product channelization and channel productization, which can even be regarded as the combination of ISP (Internet Service Provider) and ITS (Information Technology Service).
The English for ASP is Application Service Provider, and the Chinese standard translation is "Application Service Provider", which refers to a company or enterprise that provides management application solutions for commercial or individual customers. Recently, ASP has been heated by the media. IT is difficult for people in non-IT industry to understand the content of ASP in the face of a bunch of technical terms. This paper tries to unveil the mystery of ASP with simple language for readers, and has some basic understanding of the popular ASP field in IT industry.
What is 1? ASP？
Simply put, ASP is a service provider that provides services to customers. There is no essential difference between accounting firms and marriage agencies. The difference is that ASP mainly uses the Internet as its main work and business tool, and provides standardized application software, related technical consultation and management leasing services to enterprises and companies in a one-to-many way. The concept of ASP was first put forward by Americans in 1998. At present, IT is regarded as the third network business model that can promote the development of network economy and has a solid foundation by major IT vendors around the world.
Compared with the traditional outsourcing service, the main difference of ASP is that ASP is a one-to-many business model, and the services it provides are compatible and coordinated. The charging method of ASP is generally monthly.
The insiders believe that ASP generally has such "members": telecom operators, traditional IT service providers, Internet access service providers (ISPs), independent software providers (ISVs), system integrators and pure ASP companies.
According to the popular view, ASP has the following five core connotations:
A.ASP focuses on applications and provides access to and management of applications.
B.ASP service can provide users with services that can be accessed in a "customized" brand-new application system environment, without the upfront investment of resources such as servers, personnel, systems and system authorization, such as ISP, and such services generally charge ASP service fees on a monthly basis.
C.ASP adopts centralized management-ASP generally has a management center, and all customers can access it remotely through the Internet to obtain technical support and consulting services.
D. One-to-many services, that is to say, ASP provides standardized product packages, and the products have been customized to the minimum or have not been customized by customers, which has reached practical and convenient standards for industry users.
E. delivery according to the contract. In the eyes of ASP customers, ASP is an organization that provides related services according to the contents of the customer agreement, and ensures that the services of the application service system can be truly fulfilled.
Why is 2.ASP popular?
From a big perspective, the core problem that puzzles the survival and development of domestic enterprises is management. With the popularization and application of Internet, enterprise users can directly rent ASP servers and software systems to manage their own business anytime and anywhere. The advantages of doing this are: First, enterprises can save a lot of IT construction costs and greatly reduce the cost of enterprise management informatization. Secondly, users of ASP can obtain applications and services in many ways, and software service products can form a perfect, efficient and advanced enterprise management system in a very short time through the network, and quickly obtain the integrated operation management scheme of enterprises.
The rapid development of network economy and e-commerce are also the main reasons. From portal to content, from attention to verticality, networks and websites gradually turn to ASP.
According to the author's understanding, the netizen "Bird" was the first person in China to get an electric shock from ASP. 1June, 1998, he spontaneously organized "Bird House" to study, exchange and discuss ASP technology, and now it has developed into the earliest ASP application technology service provider website in chinaasp.com and China. Shanghai Reciprocal Network Co., Ltd. combined with the actual situation in China, launched the ASP platform Reciprocal Network to serve domestic enterprises, providing enterprises with the remote framework and hosting services of internal and external network facilities and applications with e-commerce as the core, creating a virtual enterprise portal (EP), and directly applying ASP to commercial proliferation.
In addition, ISP has also turned to the embrace of ASP in an all-round way, which has become the product of ISP's further development. Software vendors have a soft spot for ASP. The latest news in the industry is that China Netcom, the third largest telecom company in China, has formulated the development strategy of ASP. Hamp, the largest management consulting company in China, has positioned its eight subsidiaries in the field of enterprise internal resource planning management (ERP), Beijing Liancheng Interactive will be positioned in the field of customer relationship management (CRM), and Beijing Digital Ark will be positioned in the field of network office. HP is discussing with China Construction Bank.
ASP is rising in the tide of IT economy, and its development prospect is immeasurable.
The Development Stages and Problems of 3.ASP
Various IT roles, mainly network service providers, software vendors and ISP, are making various attempts in the ASP field according to their own advantages. At present, the services provided by ASP are various, and there is no concept of standardization and quantification. Hardware vendors are moving closer to the "soil" and power direction of ASP, while software vendors and ISP are directly involved in the front line of ASP business.
The author estimates that after a period of trial and development, ASP will develop towards service integration, the initial standardization of products and services will be established soon, and then it will enter a period of market refinement, standard formulation and maturity of ASP products, and the steady growth of ASP will eventually become the core of the business model of IT industry!
At present, on the road of ASP development, the main problems are the change of ideas: replacing purchase with leasing, replacing product distributor with service integration, replacing product economy with service economy and so on. In fact, safety and service quality are the most important things for ASP and customers. ASP has a long way to go to realize the slogan of "leasing high technology" put forward by ASP!
