【摘要】：本文論述了依托于互聯(lián)網(wǎng)技術(shù)的售水系統(tǒng)的設(shè)計與實現(xiàn)過程。在論文的開始部分首先分析了現(xiàn)階段水務(wù)企業(yè)回收水費的基本流程和方式,并指出這種方式所存在的缺陷和不足。接下來從國內(nèi)與國外兩個方面論述了自來水行業(yè)信息化的發(fā)展現(xiàn)狀態(tài)和趨勢,并指出水務(wù)企業(yè)業(yè)務(wù)流程信息化后為用戶帶來的競爭優(yōu)勢。在系統(tǒng)分析階段,首先對網(wǎng)上售水系統(tǒng)從經(jīng)濟、技術(shù)、社會等方面進行了可行性分析研究,并基于用戶的實際業(yè)務(wù)流程使用UML中的組件圖切分出多個子系統(tǒng)。使用UML用例圖確定了系統(tǒng)邊界,配合用例規(guī)約對每個角色和用例進行詳細(xì)說明,使用活動圖描述了業(yè)務(wù)流程,最后從數(shù)據(jù)流動和處理的角度對系統(tǒng)進行了建模。概要設(shè)計階段首先從宏觀的角度設(shè)計系統(tǒng)整體架構(gòu)并建立領(lǐng)域模型。依據(jù)數(shù)據(jù)流圖設(shè)計出概念數(shù)據(jù)模型(CDM)和物理數(shù)據(jù)模型(PDM),并配合數(shù)據(jù)字典對數(shù)據(jù)項進行說明,最后給出了系統(tǒng)的物理部署設(shè)計圖。在詳細(xì)設(shè)計階段根據(jù)每個模塊的業(yè)務(wù)功能,分別繪制了類圖與時序圖,從靜態(tài)和動態(tài)兩個角度對系統(tǒng)進行描述。接下來根據(jù)頁面原型設(shè)計開發(fā)程序并進行單元測試。系統(tǒng)測試階段首先介紹了測試的分類和目標(biāo),從功能、性能、易用性三個層面分別設(shè)計了測試用例并依據(jù)用例對系統(tǒng)進行測試,最后給出了測試的結(jié)果。在論文的末尾對網(wǎng)上售水系統(tǒng)在行業(yè)應(yīng)用中所發(fā)揮的作用進行了總結(jié)和展望,得出了信息化系統(tǒng)能夠改變水務(wù)企業(yè)的運營方式并增加市場競爭力的結(jié)論。
[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.
