Design And Implementation Of Online Water Selling System Based On.NET Platform

This paper discusses the design and implementation process of the water selling system based on Internet technology.At the beginning of the paper,the basic process and methods of recycling water rate of water enterprises are analyzed at the beginning of this paper,and the shortcomings and deficiencies of this method are pointed out.Next,from two aspects of domestic and foreign countries discussed the development of the water supply industry’s current status and trends,and pointed out that the water supply enterprise business process information for the user to bring the competitive advantage.In the system analysis stage,the first step of the online sale of water system from the aspects of economy,technology and society carried out a feasibility analysis,and based on the user’s actual business processes using UML component graph cut separation of multiple subsystems.Using UML use case diagram to determine the system boundary,with the use case specification of each role and use case is described in detail,use activity diagram to describe the business process.Finally,from the point of view of data flow and processing of the system modeling.In the design phase,the overall framework of the system is designed from the macro perspective,and the field model is established.According to the data flow diagram,the conceptual data model(CDM)and the physical data model(PDM)are designed,and the data are combined with the data dictionary to explain the data items.Finally,the physical design of the system is given.In the detailed design stage,according to the business function of each module,the class diagram and sequence diagram are drawn,and the system is described from two aspects of static and dynamic.Next according to the page prototype design and development process and unit test.The system testing phase first introduced the test of classification and target,from the function,performance,and ease of use of three levels were designed test cases and based on the case of the system test.Finally,the test results.At the end of the paper,the online sale of water system in the industry application in its role of summary and outlook,that the information system can change the operation mode of water enterprises and increase the market competitiveness of the conclusion.
