Design And Implementation Of C2C On-Line Application Store

With the popularity of Internet,e-commerce is widely spreading to people's daily life.With its convience and swiftness,on-line shopping wins more and more favour and greatly changed the traditional mode of shopping.And the contents for on-line tansactions expand gradully from containing real things only to the virual things as well.And because of the increasing use of smart phones and PDAs,the demand of applications bases on them booms at the same time.Apple, Inc.is the pioneer of application store which makes remarkable progress with its popular products.Afterwards,several famous enterprises of internet,mobile phone and operator followed Apple's mode,but they all have some short comings which make users with different end points suffer from great limitations.Because the demand for the applications as well as most of other websites offer applications supporting certain brands only,the project in this paper developed a on-line mall of applications,offering the users a open platform of sharing,getting and dicussing applications.It also contributes to small-and-medium-sized enterprises as they can publish their design and products and increase their competitiveness as well.It is the real open platform which does not limit to the programming languages,developing platforms or brands.The system consists of two part,one is front end which enables the users to scan the website,download and upload application,and the other is the back end which is designed for the administrators to control the resources,information privileges and so forth.The back end does not ensure that the system can operate normally but also provide the function of disaster backups and recovery.The system does not only implement the function of application publication,but also the modules of forum,comments board and FAQ so that users can exchange their experience,feelings and solutions.These modules also promote the communications between users themselves and users and the website which provide the administrators a efficient way to know the users' suggestions toward the website.The system is implemented with Apache Tomcat,MySQL database and JSP.The object-oriented principles are used during the analysis and design,including the concerns of system performance,ease of use,integrity and applicability of technology and employment as well.Though requirement analysis,preliminary Design,detailed design,the system is completed with each module fulfilled.Test methods are also took to ensure the validity,reliability,and integrity.Moreover,the disadvantages and future word are also analysed in the paper.By now the all the functions of the system has been implemented and it showed the good reliability in the functional test before release.lt also means that I have fulfilled my tasks of the research,design and implementation of the system functions which can also be a leading exploration of the new mode of on-line application store.
