【摘要】：自從工程項(xiàng)目管理軟件的應(yīng)用引入工程領(lǐng)域以來(lái),人們不再需要做很多繁雜重復(fù)的工作,并且使得工程項(xiàng)目管理的水平得到了不斷提高,同樣工程項(xiàng)目管理的工作效率也得到了進(jìn)一步提高。工程項(xiàng)目管理軟件需要對(duì)工程項(xiàng)目管理中的數(shù)據(jù)進(jìn)行實(shí)時(shí)的處理,這些數(shù)據(jù)量特別大,對(duì)它們的處理一定要是全面并且準(zhǔn)確的。因此建立一個(gè)良好的數(shù)據(jù)平臺(tái)顯得尤為重要。本文研究的便是為一家電力工程公司設(shè)計(jì)的基于Web的工程項(xiàng)目管理軟件數(shù)據(jù)平臺(tái)的設(shè)計(jì)。本文工程項(xiàng)目管理軟件基于ASP.NET平臺(tái),采用B/S結(jié)構(gòu)進(jìn)行設(shè)計(jì),采用ADO.NET數(shù)據(jù)訪問(wèn)技術(shù)進(jìn)行數(shù)據(jù)訪問(wèn)。本文研究的數(shù)據(jù)平臺(tái)采用三層架構(gòu)的模式進(jìn)行開(kāi)發(fā)。數(shù)據(jù)平臺(tái)確保該工程項(xiàng)目管理軟件成功實(shí)現(xiàn)需求分析所提出的功能需求,比如工程項(xiàng)目進(jìn)度管理,用戶權(quán)限管理,物資管理以及消息系統(tǒng)等。文中首先對(duì)需求分析進(jìn)行了概述,在此基礎(chǔ)上提出了功能需求,并且對(duì)總體設(shè)計(jì)方案進(jìn)行了概述。針對(duì)工程項(xiàng)目管理軟件所涉及的數(shù)據(jù)種類繁多,數(shù)據(jù)量龐大,數(shù)據(jù)不規(guī)范等問(wèn)題,本文對(duì)數(shù)據(jù)的來(lái)源進(jìn)行了分析,同時(shí)對(duì)數(shù)據(jù)進(jìn)行了分類,并且完成了對(duì)數(shù)據(jù)的編碼。數(shù)據(jù)平臺(tái)采用關(guān)系型數(shù)據(jù)庫(kù)進(jìn)行設(shè)計(jì),數(shù)據(jù)庫(kù)的設(shè)計(jì)采用Power Designer數(shù)據(jù)庫(kù)設(shè)計(jì)工具進(jìn)行建模,分別是概念數(shù)據(jù)模型CDM和物理數(shù)據(jù)模型PDM。具體數(shù)據(jù)庫(kù)的建立由Power Designer工具自動(dòng)生成的SQL腳本在Microsoft SQL Server 2005中創(chuàng)建。另外還對(duì)數(shù)據(jù)驅(qū)動(dòng)進(jìn)行了探討,封裝了DBAccess類進(jìn)行對(duì)數(shù)據(jù)庫(kù)最底層的訪問(wèn),對(duì)三層架構(gòu)中的每一層實(shí)現(xiàn)也選取了一部分進(jìn)行介紹。同時(shí)對(duì)數(shù)據(jù)庫(kù)的安全以及備份做了分析,并且詳細(xì)說(shuō)明了數(shù)據(jù)庫(kù)數(shù)據(jù)的自動(dòng)復(fù)制。最后完成測(cè)試,并且對(duì)功能實(shí)現(xiàn)進(jìn)行部分展示。
[Abstract]:Since the application of engineering project management software has been introduced into the engineering field, people no longer need to do a lot of complicated and repetitive work, and the level of engineering project management has been continuously improved. The work efficiency of project management has also been further improved. The engineering project management software needs to process the data in the project management in real time. The data amount is very large, so the processing must be comprehensive and accurate. Therefore, the establishment of a good data platform is particularly important. This paper studies the design of project project management software data platform based on Web for a power engineering company. In this paper, the project management software is designed based on ASP.NET platform, using B / S structure and ADO.NET data access technology. The data platform studied in this paper adopts three-tier architecture to develop. The data platform ensures that the project management software successfully implements the functional requirements of the requirements analysis, such as project schedule management, user authority management, material management and message system. In this paper, the requirement analysis is summarized firstly, and then the functional requirements are put forward, and the overall design scheme is summarized. In view of the problems of various kinds of data, huge amount of data, non-standard data and so on, this paper analyzes the source of the data, classifies the data at the same time, and completes the coding of the data. The data platform is designed by relational database, and the database is modeled by Power Designer database design tool, which is the conceptual data model CDM and the physical data model PDM respectively. The establishment of concrete database is created by SQL script generated automatically by Power Designer tool in Microsoft SQL Server 2005. In addition, the paper also discusses the data drive, encapsulates the DBAccess class to access the bottom layer of the database, and introduces the implementation of each layer in the three-tier architecture. At the same time, the security and backup of database are analyzed, and the automatic replication of database data is explained in detail. Finally, the test is completed, and the implementation of the function is partially demonstrated.
