The Design And Implementation Of Natural Gas Business Charge System Based On MVC

Chargeable business work of natural gas industry has always been a core business of the industry, is also one of the more complex areas of the business. This is mainly embodied in the following aspects: first, the business area has a high requirement for the security of the system stability, any data manipulation must be atomic, namely or correct operation, or not to do, any data ambiguity can be fatal; Second, the business area on the system performance and high requirement of concurrent processing capability. A natural gas company hold tens of thousands of users, hundreds of thousands of users is widespread, users capture to expend time and relatively concentrated, so the system must support a number of concurrent operation; Third, the system must provide the other independent business system data interface, such as POS terminals, bank transfer system, IC card online payment system, etc.Based on "standard gas company of business" as the prototype, through to the natural gas industry business charge of investigation and study, work and management process integration to improve the business of key nodes, and through the software system to implement. Article in accordance with the software development and design process describes the system requirements analysis, overall design, detailed design and system implementation process. In the process of the system design, using UML use case diagram and use case specification chart analysis system functional requirements; The sequence diagram to describe system module detailed design; Described using data flow diagram and data dictionary database development process.Through the actual design and development, the system covers the gas industry operating charge for all the key parts of the business, to adapt to the different types of pay cost mode and the table type, through a certain degree of hardware support and the code of a small scale adjustment, the system can adapt to most of the actual business requirements of the gas company business hall, has good popularization value.
