With the rapidly development of electronic commerce, the competitions between enterprises have been getting more and more turbulent. In order to win business in such a highly competitive environment, it has to not only implement customized marketing strategy but also have a timely response whenever there is any change in the business environment. Currently, in most companies, whenever the marketing people wants to implement a new sales promotion program, he has to communicate it with the MIS department and ask it to rewrite the Web system and pages. It is quite often a very time-consuming as well as strenuous process. In this research, we have explored all popular and important sales promotion models. Based on these models, an object-oriented Web system has been designed and developed. There is an interface by which the marketing people can set the new sales promotion program and then, the Web system can execute it immediately afterwards. The interface, allows the marketing people easily to select target customers, conditions for getting bonus and contents of bonus to set a new sales promotion program. That is, the marketing people can let the Web system execute a new sales promotion program whenever he wants without the help of system programmers. In addition, the whole design is object-oriented. It lets the system have very high portability.

Estas plataformas provêm uma série de serviços especializados, permitindo assim que os programadores possam se concentrar mais nas regras de negócio das aplicações que desenvolvem. Atualmente a plataforma J2EE (Java 2 Enterprise Edition) da SUN Microsystems é uma das mais populares para este fim. Infelizmente, tolerância a falhas, um requisito não funcional cada vez mais presente nas aplicações, não é diretamente suportada pela especificação J2EE. Aplicações desenvolvidas sobre essa plataforma devem, elas mesmas, implementar os mecanismos para tolerância a falhas requeridos, ou usar implementações da plataforma que possuam características de tolerância a falhas. Nesta dissertação nós apresentamos o projeto e a implementação de um servidor de aplicações J2EE que implementa esses mecanismos. Diferentemente de outras soluções disponíveis, que usam replicação passiva, o nosso sistema usa replicação ativa para prover alta confiabilidade de forma totalmente transparente para as aplicações. / The use of developing platforms to support the implementation of distributed applications has become a trend. These platforms provide a number of specialized services that help programmers to focus on the business logic of the applications they develop, instead of wasting precious time with the implementation of infrastructure services. J2EE (Java 2 Enterprise Edition) is a platform backed up by SUN Microsystems that has lately gain a lot of attention. Unfortunately, the J2EE specification does not provide any support for fault tolerance, a non-functional requirement more and more necessary for distributed applications. Developers of such applications must themselves provide the necessary mechanisms to fulfill the requirements of the applications. Alternatively, they can use implementations of the platform that are themselves fault tolerant. In this dissertation we present the design and implementation of such a platform. Unlike other implementations available, that use passive replication, our approach uses active replication to provide a solution that is highly reliable and totally transparent to the application.
