摘 要

隨著在校大學(xué)生的不斷增加,學(xué)生選課系統(tǒng)也是學(xué)校對學(xué)生管理中不可缺少的一部分。以往的選課方法是使用人工的方法管理文件檔案,這種管理方式存在許多的缺點(diǎn):效率低、保密差,另外時(shí)間一長,將產(chǎn)生大量的文件和數(shù)據(jù),這對于查找、更新和維護(hù)都帶來不少的困難。隨著科學(xué)技術(shù)的不斷提高,計(jì)算機(jī)已經(jīng)進(jìn)入人類社會的各個(gè)領(lǐng)域并發(fā)揮著越來越重要的作用。作為計(jì)算機(jī)應(yīng)用的一部分,實(shí)用技術(shù)絕對選課信息進(jìn)行管理,具有手工管理所無法比擬的優(yōu)點(diǎn)。例如:查找方便、可靠性高、存儲量大、保密性好、壽命長、成本低等。
本文通過分析瀏覽器/服務(wù)器結(jié)構(gòu)的特點(diǎn)并結(jié)合選課的實(shí)際情況簡單的介紹了系統(tǒng)各功能模塊及數(shù)據(jù)庫的設(shè)計(jì),著重討論了用ASP.NET技術(shù)和SQL Server 2005 開發(fā)選課系統(tǒng)的數(shù)據(jù)庫的訪問技術(shù)和動態(tài)網(wǎng)頁制作技術(shù),并給出了一些可以實(shí)現(xiàn)的核心代碼。通過該系統(tǒng),使學(xué)生可以很方便的在校園網(wǎng)上進(jìn)行網(wǎng)上選課。該系統(tǒng)在Windows XP系統(tǒng)和VS2005平臺下開發(fā)完成,使用C#作為ASP.NET的開發(fā)語言,SQL Server 2005作為數(shù)據(jù)庫。系統(tǒng)有較高的安全性和較好的性能。其中連接數(shù)據(jù)庫的字符串可以隨時(shí)在web.config里修改。代碼盡量使用了存儲過程和盡量減少了數(shù)據(jù)庫連接打開的時(shí)間來提高性能。
本文除了有對程序的系統(tǒng)分析、總體設(shè)計(jì)、數(shù)據(jù)庫設(shè)計(jì)、功能實(shí)現(xiàn)等主體部分外,還介紹了ASP.NET和數(shù)據(jù)庫的結(jié)合的基本內(nèi)容。
關(guān)鍵詞:學(xué)生選課、 瀏覽器/服務(wù)器、 ASP.NET、VS 2005、 SQL Server 2005數(shù)據(jù)管理系統(tǒng)

 

Abstract

With the continuous increase in college students, students in schools of students elective system is also an integral part of management. Previous elective method is to use artificial methods to manage file archives, this management approach has many disadvantages: low efficiency, poor security, while over time, will generate a large number of documents and data, which for finding, updating and maintenance of bring a lot of difficulties. With the continuous improvement of science and technology, the computer has access to all areas of human society, and play an increasingly important role. As a part of computer applications and practical management of information technology is absolutely elective, with manual management incomparable advantages. For example: to find convenient, high reliability, large memory capacity, security and good, long life and low cost.
This paper analyzes the browser / server structure is characterized by combining the actual situation of elective a brief introduction of the system of functional modules and database design, focused on using ASP.NET technology and SQL Server 2005 Developer elective system, access to the database technology and dynamic web production techniques, and give some of the core code can be achieved. Through the system so that students can easily online Online Course on campus. The system is Windows XP system and VS2005 platform is developed using C # as the ASP.NET development language, SQL Server 2005 as a database. System has a higher security and better performance. In which the database connection string in the web.config where you can change at any time. The code to make use of the stored procedure and to minimize the database connection open time to improve performance.
This addition to the program's system analysis, overall design, database design, function and so the main part of the implementation, but also describes the combination of ASP.NET and database elements.
Keywords: Student elective, browser / server, ASP.NET, VS 2005, SQL Server 2005 database management system
