Design and Implementation of Status Authentication System Bad On ASP
Sabato G, Wilson N.
Abstract
With the rapid development of internet technologies, as a newly developed trading operation mode, more and more emphasis are placed on electronic trading. Status authentication system is an esntial component of electronic trading, which gives more conveniences and fastness to customers who are in favor of internet shopping. This thesis deals with how to construct status authentication system with newly developed internet technologies, improve the trading capabilities of internet trading platform and give a full play of the information of the internet. The programming of status authentication system and ur interface are constructed with ASP technology. Back-end databa is constructed with SQL S
ERVER 2008. A cure access to status authentication system databa is implicated with ADO. Demand-analysis, business procedure, systemic structure and databa mode of status authentication system are analyzed and designed with three tire structure. The advantages of ASP and three tire structure are discusd, and a status authentication system is constructed.
Key words: Status authentication system; ASP; Three tire structure; Databa
1 The Summary of online shopping
1.1 Online shopping definition
Online mall is similar to ordinary mall, is to u various means of electronic commerce from buy to ll deal process virtual store, so as to reduce the intermediate links, eliminate operating costs and agency in the middle of the price difference, and increa market circulation, with a huge space for development. As far as possible,
also the consumer, drive the rapid development of the company.
带子狼1.2 Construction of online mall

Such as using a special platform. Advantage is low investment cost, high efficiency. Enterpris only need to register and submit relevant information you can u the establishment of the online platform to complete you’re online shopping. For lack of funds and technical support of corporate entrepreneurship can make full u of the mall. Defect is unable to effectively control space, domain names, procedures, and other important resources. In the long run can produce adver effect to the enterpri network sales.
Shopping mall and relative platform independent relatively complex network mall, invest more. But the effect is better. Enterpris can choo the programming language, ASP language, have a lower development costs and a large market coverage, but the safety problem is outstanding. The PHP language is characterized by convenience, flexible, very suitable for program development. The most commonly ud programming language mainstream products. Weakness is not suitable for big projects and condary development. In the high-end application ability is limited. Have an ECSHOP, SHOPEX, etc.JA V A language to build online shopping system in the current products on the market is very little. Have superior language features, built by the online shopping system in safety, functional expansibility and condary development has very excellent performance. But high development cost, the difficulty is big. Usually only u big business, government, etc.

2 Network mall development process
2.1 The requirements analysis
Understand customer needs, including company introduction, item description, basic functional requirements, business process, etc.
2.2 Construction scheme design online mall
According to the demand analysis, according to the actual situation of enterpris, choo suitable for the enterpri network mall construction plan. Such as web hosting rvice or buy your own rver.
2.3 Host the DNS query
Domain name is part of the image of enterpri. Easy to remember and highlight the characteristics of enterpri name easy to improve enterpri brand image.
2.4 Interface design, manufacture, and modification.
The code a good interface design to the information relea at the same time to the company's business philosophy and purpo accurate interpretation. And can attract the customers. At the same time for architecture design, coding. To provide customers with convenient browsing navigation, suitable business function modules, such as information relea system, product display, shopping cart system, etc. To suit demand of the enterpri, this step needs to actively cooperate with customers.
2.5 debugging function
Debug the whole system function, to provide customer tests and listen to customer comments, a change in a timely manner.
2.6 Relea宽阔反义词
After through customer audit through online shopping system, can be uploaded to the site to run the rver, the formal relea. And timely after-sale technical support and maintenance.
3 The key technologies of online shopping
3.1 The
Definition: Microsoft is Microsoft for XML Web rvices platform. The software will u a way of unified, personalized information, equipment and personnel cloly linked together.XML Web rvices allow applications regardless of what kind of operating system, device, or adopted by a programming language, can through the Internet to communicate and share data.Microsoft platform provides create XML Web rvices at the same time meet the needs of the integrate the rvices together. Specifically, the platform includes development tools, XML WEB rvices, the client and rver. The experience.
3.2 XML Web rvices
The basis of XML Web rvices is the programming model. The core of is technology. Is to other Application data and rvices application logic unit. Application using the standard Web protocol and data format (such as HTTP, XML
and SOAP) access to the XML Web rvices, has nothing to do with each XML Web rvices is implemented. Through XML Web rvices, customers and urs from one rvice to another, from one application, or even from one environment to another environment will be very easy. Allows the ur plane degree computer world will become simpler.

3.3. The framework
The Framework ( Framework) is developed by Microsoft for more than a language component development and execution environment, it provides a unified cross-language programming environment. The purpo of the framework is convenient for developers to more easily build Web applications and Web rvices, making the Internet between various applications, Can u Web rvices to communicate. Is mainly compod of the following two: Common Language Runtime (CLR: Common Language Runtime) CLR manages memory, thread execution, code safety verification, compilation, and other system rvices. CLI is a t of operation environment, including general system, the middle of the ba class library has nothing to do with the machine code, called the common intermediate language (CLI).The CLR is confirm password in accordance with the CLI platform operation. The CLR in CLI instruction before implementation compiled into the original mechanical code in a timely manner.
3.4 ASP
The predecessor of the ASP technology, ASP is a rver-side scripting technology developed by Microsoft, but to let the script embedded in a web page by intent web rver implementation. ASP.
NET includes all kinds of needed rvices to facilitate Web application developers to generate the enterpri level The program. Provides developers with a new kind of programming structure and model of the generated application has better Scalability and stability, and better curity protection, is a unified model for Web application development.
Developers can gradually add ASP in the existing ASP application capabilities, to enhance and improve its function at any time. All ASP applications can be applied to the whole. The Framework, compared with ASP,
ASP application development can u any. NET compatible languages, such as c # and JScript. NET.., Visual Basic, etc. And instant interpreter speed is much quicker than ASP.ASP is a kind of natural layered architecture, the SQL Server, Oracle, consistent access to all sorts of data and public data sources such as, and through the data provider is a Datat and. NET Frame Work of two core components complete decomposition data access tasks. For large-scale complicated information system development and maintenance.
4 Three layer structure
4.1 C/S structure
年度培训计划表
C/S (Client/Server), namely the Client/Server structure is a kind of system architecture, currently most application software system bad on C/S structure, in the form of this structure can make full u of the advantages of both ends hardware environment, make reasonable tasks assigned to the Client and the Server side, reduce the communication overhead of the system. In this structure, the rver is the core of the network, the customer is the foundation of the network, the client rver to obtain the required network resources, the rver must provide for the customer network resources.
饺子怎么画简笔画C/S structure can give full play to the Client's ability to process, make a lot of work on the Client side processing and then submitted to the rver, business processing logic is mainly, on the Client side and could be called Fat Client (Fat Client) structure. So the client speed accordingly.
4.2 B/S structure
B/S (Browr/Server) structure namely the Browr and Server structure. Is a variable of C/S structure And the improved structure, with the rapid development of Internet technology and the ri. Under B/S structure, the application rver implementation of professional software applications, and Web rver implementation customer performance, becau the client through the browr to make the business process, greatly reduce the cost of system maintenance and upgrade and workload, si
mplify the client computer load at the same time. Is the first choice for today's application software architecture.
