发布时间：2019-06-06 00:54
【摘要】：本文论述了依托于互联网技术的售水系统的设计与实现过程。在论文的开始部分首先分析了现阶段水务企业回收水费的基本流程和方式,并指出这种方式所存在的缺陷和不足。接下来从国内与国外两个方面论述了自来水行业信息化的发展现状态和趋势,并指出水务企业业务流程信息化后为用户带来的竞争优势。在系统分析阶段,首先对网上售水系统从经济、技术、社会等方面进行了可行性分析研究,并基于用户的实际业务流程使用UML中的组件图切分出多个子系统。使用UML用例图确定了系统边界,配合用例规约对每个角色和用例进行详细说明,使用活动图描述了业务流程,最后从数据流动和处理的角度对系统进行了建模。概要设计阶段首先从宏观的角度设计系统整体架构并建立领域模型。依据数据流图设计出概念数据模型(CDM)和物理数据模型(PDM),并配合数据字典对数据项进行说明,最后给出了系统的物理部署设计图。在详细设计阶段根据每个模块的业务功能,分别绘制了类图与时序图,从静态和动态两个角度对系统进行描述。接下来根据页面原型设计开发程序并进行单元测试。系统测试阶段首先介绍了测试的分类和目标,从功能、性能、易用性三个层面分别设计了测试用例并依据用例对系统进行测试,最后给出了测试的结果。在论文的末尾对网上售水系统在行业应用中所发挥的作用进行了总结和展望,得出了信息化系统能够改变水务企业的运营方式并增加市场竞争力的结论。
[Abstract]:This paper discusses the design and implementation of water sales system based on Internet technology. At the beginning of the paper, the basic process and method of recovering water fee in water enterprises are analyzed at first, and the defects and shortcomings of this method are pointed out. Then it discusses the present state and trend of the informatization of tap water industry from two aspects of domestic and foreign, and points out the competitive advantage brought by the informatization of business process of water enterprises to users. In the stage of system analysis, the feasibility of online water sales system is analyzed and studied from the aspects of economy, technology, society and so on, and several subsystems are divided into several subsystems based on the actual business process of users using the component diagram of UML. The system boundary is determined by UML use case diagram, each role and use case is explained in detail with use case specification, the business process is described by activity diagram, and the system is modeled from the point of view of data flow and processing. In the outline design stage, the overall architecture of the system is designed from a macro point of view and the domain 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 items are explained with the data dictionary. Finally, the physical deployment design diagram 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 respectively, and the system is described from the static and dynamic angles. Next, according to the page prototype design and development program and unit test. In the testing stage of the system, the classification and objectives of the test are introduced, and the test cases are designed from three aspects of function, performance and ease of use, and the system is tested according to the use cases. Finally, the test results are given. At the end of the paper, the role of online water sales system in the industry application is summarized and prospected, and the conclusion is drawn that the information system can change the operation mode of water enterprises and increase the market competitiveness.
