【摘要】：自從工程項目管理軟件的應用引入工程領域以來,人們不再需要做很多繁雜重復的工作,并且使得工程項目管理的水平得到了不斷提高,同樣工程項目管理的工作效率也得到了進一步提高。工程項目管理軟件需要對工程項目管理中的數(shù)據(jù)進行實時的處理,這些數(shù)據(jù)量特別大,對它們的處理一定要是全面并且準確的。因此建立一個良好的數(shù)據(jù)平臺顯得尤為重要。本文研究的便是為一家電力工程公司設計的基于Web的工程項目管理軟件數(shù)據(jù)平臺的設計。本文工程項目管理軟件基于ASP.NET平臺,采用B/S結(jié)構(gòu)進行設計,采用ADO.NET數(shù)據(jù)訪問技術進行數(shù)據(jù)訪問。本文研究的數(shù)據(jù)平臺采用三層架構(gòu)的模式進行開發(fā)。數(shù)據(jù)平臺確保該工程項目管理軟件成功實現(xiàn)需求分析所提出的功能需求,比如工程項目進度管理,用戶權限管理,物資管理以及消息系統(tǒng)等。文中首先對需求分析進行了概述,在此基礎上提出了功能需求,并且對總體設計方案進行了概述。針對工程項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)范等問題,本文對數(shù)據(jù)的來源進行了分析,同時對數(shù)據(jù)進行了分類,并且完成了對數(shù)據(jù)的編碼。數(shù)據(jù)平臺采用關系型數(shù)據(jù)庫進行設計,數(shù)據(jù)庫的設計采用Power Designer數(shù)據(jù)庫設計工具進行建模,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)庫的建立由Power Designer工具自動生成的SQL腳本在Microsoft SQL Server 2005中創(chuàng)建。另外還對數(shù)據(jù)驅(qū)動進行了探討,封裝了DBAccess類進行對數(shù)據(jù)庫最底層的訪問,對三層架構(gòu)中的每一層實現(xiàn)也選取了一部分進行介紹。同時對數(shù)據(jù)庫的安全以及備份做了分析,并且詳細說明了數(shù)據(jù)庫數(shù)據(jù)的自動復制。最后完成測試,并且對功能實現(xiàn)進行部分展示。
[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.
