CORBA-based e-commerce application testing architecture Abstract: E-commerce systems are specialized instances of distributed processing systems. As systems become more complex and geographically distributed, it is becoming increasingly difficult to conduct cost-effective, systematic and comprehensive testing on such systems. Using CORBA to facilitate the development and testing of e-commerce systems can greatly improve testability and directly shorten the time-to-market cycle by decreasing the test effort.
The approach is illustrated by the implementation of an experimental e-commerce system and the corresponding testing architecture. Article :.

This architecture is simple. It may be appropriate and sufficient for some kinds of Internet commerce applications. On the other hand, it may be more difficult to expand this architecture as the online business grows, or to incorporate new technologies and components as they become available. Many technical details will become clearer as we discuss the technology in later lectures.
An approach to distributed transactions originally created at Open Market The core idea of this architecture is to separate the content management from the transaction management Transaction server is separated from the merchant server. Multiple catalog merchant servers can share the capacity of a single transaction server. Content-oriented parts of the system can scale independently from the transaction-oriented parts. This architecture allows separate management of different system facilities e. There may or may not be a separate payment gateway, depending on which payment methods are supported.
Consumers are members of communities of interest, which provide authentication and customer services. When a consumer buys something, the necessary payment and shipping information is routed from her home community to the seller. The seller may also use some of the federated services for payment and other functions.
Clearinghouse: Responsible for tying the network together. Customers Browse information, make purchases, and request for customer service. Home communities Consumers join home communities on the basis of interests, services offered, or the degree of privacy protection offered. Sellers Includes merchants, service providers, and publishers.
Payment service Provides support for various payment mechanisms as a Web service. Logistics service Handles shipping, returns, and other services. The core idea of the OBI architecture is to split the functionality of the commerce system between buy-side activities and sell-side activities so that each organization manages those functions logically connected to it. Requisitioner selects supplier 2. Requisitioner browses catalog and orders Buyer Purchasing Server with list of suppliers 3.
Catalog server routes order to OBI server 5. Seller routes order for fulfillment and payment 4.
Seller sends OBI order request to buyer 6. The requisitioner uses a Web browser to connect to the buyer purchasing server and selects a hyperlink to the seller catalog server. The seller catalog server authenticates the requisitioner based on a digital certificate signed by the buyer, and allows the requisitioner to browse, select items, and check out. The seller catalog server sends the content of the order to the seller OBI server. The requisitioner specifies any annotations to the order, and internal approval process takes place.
The seller obtains payment authorization if necessary and begins order fulfillment.
The real benefit of the OBI architecture can be seen only when there are multiple buy-side companies trading with multiple sell-side companies. When this happens, the buyer is able to manage its requisitioner database and approval system centrally, and it can use those systems seamlessly with multiple trading partners.
Similarly, the seller can leverage a master catalog and order management system to serve multiple buyers. Winfield Treese and Lawrence C.
