Design And Implementation Of Message-Oriented Middleware Used In Small Payment System

As the rapid development of computer technology, the applications of distributed systems are becoming wider and wider. Large-scale application software usually requires the software and hardware running on distributed network. And it needs the operation among different platform, different environment and different database. So there must be a development and runtime environment based on standards, independent hardware and operating system. This is middleware technology. As the experts say, middleware is so important just like the operating system and database.Firstly, I introduce the background of the industry. Introduce the history of middleware technology.I have worked as an intern in Tongtech, which is a famous middleware product company. And had the advantage of actually participated in the project of Message-Oriented Middleware used in small payment system. At the same time can more clearly understand the similar products. In the paper, I use the software engineering analysis method from the requirement, especially the requirement of small payment system of People's Bank of China. Give out a product design model for native middleware company to compete with large foreign company.I put the focus on two models QCU and network that I actually participate. Give out the description of analysing and designing from the overall structure to the detail of function and technology. That the middleware products give the upper system is only some API Interface. But by calling these interfaces, completely not concerned about the underlying messaging details. This is why we need Message-Oriented.In the implementation, as what we design is a middleware, only provide some interface to the upper side. And the development of People's Bank Information Centre is confidential. In order to achieving function and displaying the intuitive, I make some demos using these interfaces and give out the result on the console. And give out the explanation according to the small payment system.Give out the design ideas for small generic middleware through the analysis of the project and development. Module independence and reuse is the most important of all.
