At the same time, the development of systems theory, systems and design features are introduced. Key word ASP，SQL，news management，databaseWith the popularization of Internet, more and more companies set up their own WWW sites, enterprises can display products through the website, publishing the latest developments, with users sharing and communication to establish contact with partners, as well as e-commerce. Information Management System which is an enterprise Web site an important part of it bears a double role, on the one hand, the dynamic can be used to release the new product or new development projects, on the other hand, the timely notice to their customers business performance, Progress in technology and research and development, in particular, recommend or preferential projects, products and services to attract customers, expand customer base.Management of traditional news sites in two ways, one static HTML page, update the information needed to re-create the page and then upload the page and modify the corresponding links, the efficiency of this approach is too low because we have little use. The second is based on ASP and scripting languages, dynamic Web pages and databases, through the application of procedures to deal with news, this is way more popular. However, due to the limitations of ASP allows the system itself, there are some insurmountable flaws, and ASP.NET technology has taken on the system performance has been greatly improved, the main performance in the following aspects:1. ASP page to open as a result of each must be compiled to explain the process, so when the page opens in the rate of repeated there is no upgrade, and only need a ASP.NET page do not need to recompile compiled until the page has been modified or Web Application process restarted. This makes the speed in a number of visits has greatly improved. 2. As the ASP does not provide any output data for the content of the components, so writing a database using ASP page can use the Record Set Object ADO to read records of transaction, while the ASP provided through the DataGrid, such as ADO.NET database and database components can be directly Contact. 3. ASP support real-time application updates. Administrators do not have to turn off the network server or even do not have to stop running the application can update the application on file. Application documents will never be locked, so even when the program runs in the paper can be overwritten. When the document is updated, the system will convert to the new moderate version. 4. ASP take the code-behind approach to the preparation of the code makes the code easier to prepare, structure more clearly, reducing the system development and maintenance of the complexity and the cost of.1 System Development Principle1.1 The System Architecture Model of ASP-based TechnologyASP is a three-tier system structure: UI Layer, Business Logic Tier and data layer.UI layer is responsible for interaction with the user, receiving user input and server-side data from present to clients. Business Logic Tier is responsible for receiving requests from browser requests to the data layers and at the same time the results of the request sent to the browser. It consists of Web Forms, XML Web services and service composition components. Web Forms ASP.NET which is the core of the application, it is presented to customers based on data and information as well as to respond to and deal with customers and display interactive Web form generated based on information and data. Data layers to manipulate data through the ADO.NET layer for business logic to provide data services, such as storing the results of data manipulation and return to the results of data retrieval.1.2 The principle of access to the database ADO.NETConnected with the database, ADO.NET provide the following three kinds of ways: through ODBC connected; connected through OLEDB; directly connected with the SQL Server. Application of three kinds of ways as a result of differences in levels, making the efficiency from low to high, high to low independence. Connected to the database for data processing, there are two kinds of ways, that is, through a Dataset to the isolation of heterogeneous data sources, and the other is a stream to read from the data source (Data Reader mode). Traditional application is to create a connection to the database, in the process is running the whole way to maintain connections to the design. ASP.NET taken disconnected mode data structure. When a browser requests a page to the Web server, the server to deal with this request, the requested page and send to your browser, and then connection was disconnected until the next browser request issued. ADO.NET Another innovation is the introduction of a data set (Dataset). A data set is the relationship between memory map to provide high-speed data buffer. Data set of data sources know that they can be adopted by the program or transferred from the data warehouse data were generated, to fill. Regardless of where the data acquisition, data sets are the same procedure through the use of templates to be operated, and its potential to use the same data buffer.2 Systems Functional Designs2.1 Systems Function StructuresThe news management system in Windows 2000 Server operating system platforms, Web server IIS, the database server for Microsoft SQL Server2000, development tools used in Microsoft Visual Studio. NET and DreamWeaver. Its work processes as follows: the user login through the authority to determine the general user can only browse, read and query information, registered users can be completed in addition to the ordinary user, but also can enter information for news management module input, modify, and delete operations. In addition to registered users outside the system administrator can only be recorded on its own news operation for excision.2.2 Systems Function Characteristics(1) Simple, user-friendly: complete control of page layout, making information easier entry work; many options including news categories, such as the source of departments only need to click the mouse can be completed; In addition, the follow-up message also appears allow users to clear their own operations. (2) Can be seen immediately: the handling of the press (including the entry, modify, delete) will be the corresponding column on the home page is displayed to immediate release, immediate results function. (3) Function: include common site in all aspects of information management: information input, browse, delete, modify, search and other aspects, the full realization of the Web site of the real-time information management requirements. (4) To facilitate transplantation: for different enterprises, with some slight modifications need to be able to develop for the companys Web site features news management system.3 Systems Detailed DesignsCore functions of the system through a number of functional modules achieved. Specific design process is as follows: System login: The module responsible for the user are divided into general users and registered users to achieve the management of user rights. (2) News View: The module is responsible for all the news page web site lists information, including the title, type, source and date field departments, and each title has been made news a hyperlink, click the page they will be able to Jump news reader. (3) News reader: in other pages or click the title link to read into the news pages, at this time, detailed information of each information will be removed, including the content, title, keywords, and relatively fixed in accordance with the format placed in different pages region, the use of all the news about the same page layout, only the contents of the field corresponding to different In addition, the location of other pages can be dynamically placed in other components, such as web site logo, such as the page banner ads link to pictures, this can be easily to achieve the effect of illustrations in reading. (4) News Inquiry: The module provides a press inquiry, type to be selected to find the content and classification of information can quickly find the information in line with the conditions and results output. (5) News Management: The module listed in the registry is responsible for the registration page the user has issued a news and information and did not delete, the user can press to delete the article, modify. In addition to non-news publisher is not outside the system administrator has the authority to deal with information which, so different users access to this page will display different content. (6) News entry and modification: a press registered users need to input the content, including title, keyword, type, source of departments, such as release date, at the same time from the login module to be user name, this information will be saved into the database. The module is also responsible for editing the updated state, then, it will light the Title field values on the page to initialize the control.21.24asp的網(wǎng)站新聞管理系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)摘要利用ASP和SQL技術(shù)開(kāi)發(fā)的網(wǎng)站新聞管理系統(tǒng)，實(shí)現(xiàn)了網(wǎng)站新聞的動(dòng)態(tài)管理，使得對(duì)信息的管理更加及時(shí)、高效，提高了工作效率。同時(shí)對(duì)系統(tǒng)的開(kāi)發(fā)原理、系統(tǒng)的功能特點(diǎn)和設(shè)計(jì)方案進(jìn)行了介紹。【關(guān)鍵詞】ASP，SQL，新聞管理，數(shù)據(jù)庫(kù)隨著Internet的普及，越來(lái)越多的企業(yè)建立了自己的WWW網(wǎng)站，企業(yè)通過(guò)網(wǎng)站可以展示產(chǎn)品，發(fā)布最新動(dòng)態(tài)，與用戶(hù)進(jìn)行交流和溝通，與合作伙伴建立聯(lián)系，以及開(kāi)展電子商務(wù)等。其中新聞管理系統(tǒng)是構(gòu)成企業(yè)網(wǎng)站的一個(gè)重要組成部分，它擔(dān)負(fù)著雙層作用，一方面可以用來(lái)動(dòng)態(tài)發(fā)布有關(guān)新產(chǎn)品或新開(kāi)發(fā)項(xiàng)目，另一方面又可以及時(shí)向顧客公告企業(yè)經(jīng)營(yíng)業(yè)績(jī)、技術(shù)與研發(fā)進(jìn)展、特別推薦或優(yōu)惠的工程項(xiàng)目、產(chǎn)品和服務(wù)，從而吸引顧客，擴(kuò)大顧客群。傳統(tǒng)的網(wǎng)站新聞管理方式有兩種，一是靜態(tài)HTML頁(yè)面，更新信息時(shí)需要重新制作頁(yè)面然后上傳頁(yè)面并修改相應(yīng)鏈接，這種方式因?yàn)樾侍鸵巡欢嘤?。二是基于ASP和腳本語(yǔ)言，將動(dòng)態(tài)網(wǎng)頁(yè)和數(shù)據(jù)庫(kù)結(jié)合，通過(guò)應(yīng)用程序來(lái)處理新聞，這是目前較為流行的做法。但是由于ASP本身的局限性使得系統(tǒng)有一些不可克服的缺陷，而采取了ASP.NET技術(shù)的系統(tǒng)性能上有了很大的改善，其主要表現(xiàn)在以下幾方面：1由于ASP頁(yè)面每次打開(kāi)都必須經(jīng)過(guò)先編譯后解釋的過(guò)程，所以頁(yè)面在反復(fù)打開(kāi)時(shí)速度沒(méi)有任何提升，而ASP.NET頁(yè)面只需要一次編譯后不需要重新編譯，直到該頁(yè)面被修改或Web應(yīng)用程序重新啟動(dòng)。這使得在多次訪問(wèn)時(shí)速度有了極大的提升。2由于ASP沒(méi)有提供任何輸出數(shù)據(jù)為內(nèi)容的元件，所以在使用ASP撰寫(xiě)數(shù)據(jù)庫(kù)頁(yè)面時(shí)只能借助ADO的Record Set對(duì)象逐筆讀取記錄，而ASP通過(guò)ADO.NET提供的DataGrid等數(shù)據(jù)庫(kù)元件可以直接和數(shù)據(jù)庫(kù)聯(lián)系。3ASP支持應(yīng)用程序的實(shí)時(shí)更新。管理員不必關(guān)掉網(wǎng)絡(luò)服務(wù)器或者甚至不用停止應(yīng)用程序的運(yùn)行就可以更新應(yīng)用文件。應(yīng)用程序文件永遠(yuǎn)不會(huì)被加鎖，因此甚至在程序運(yùn)行時(shí)文件就可以被覆蓋。當(dāng)文件更新后，系統(tǒng)會(huì)溫和地轉(zhuǎn)換到新的版本。4ASP采取code-behind方式編寫(xiě)代碼使得代碼更易于編寫(xiě)，結(jié)構(gòu)更清晰，降低了系統(tǒng)的開(kāi)發(fā)與維護(hù)的復(fù)雜度和費(fèi)用。1系統(tǒng)的開(kāi)發(fā)原理1.1 基于ASP技術(shù)的系統(tǒng)結(jié)構(gòu)模型ASP結(jié)構(gòu)是一個(gè)三層系統(tǒng)：UI層、業(yè)務(wù)邏輯層和數(shù)據(jù)層。UI層負(fù)責(zé)與用戶(hù)交互，接收用戶(hù)的輸入并將服務(wù)器端傳來(lái)的數(shù)據(jù)呈現(xiàn)給客戶(hù)。業(yè)務(wù)邏輯層負(fù)責(zé)接收瀏覽器傳來(lái)的請(qǐng)求并將請(qǐng)求傳給數(shù)據(jù)層，同時(shí)將請(qǐng)求處理結(jié)果發(fā)給瀏覽器。它由Web表單、XML Web服務(wù)和組件服務(wù)組成。其中Web表單是ASP.NET應(yīng)用程序的核心所在，它是向客戶(hù)呈現(xiàn)數(shù)據(jù)和信息的基礎(chǔ)，也是響應(yīng)和處理客戶(hù)與顯示的Web表單交互生成的信息和數(shù)據(jù)的基礎(chǔ)。數(shù)據(jù)層是通過(guò)ADO.NET操縱數(shù)據(jù)為事務(wù)邏輯層提供數(shù)據(jù)服務(wù)，如存儲(chǔ)數(shù)據(jù)操作結(jié)果、返回?cái)?shù)據(jù)檢索結(jié)果等。1.2 ADO.NET訪問(wèn)數(shù)據(jù)庫(kù)的原理與數(shù)據(jù)庫(kù)相連，ADO.NET提供了如下3種方式：通過(guò)ODBC相連；通過(guò)OLEDB相連；直接與SQL Server相連。3種方式由于應(yīng)用層次的差異，使得效率由低到高，獨(dú)立性由高到低。對(duì)于相連數(shù)據(jù)庫(kù)的數(shù)據(jù)處理，也有2種方式，即一種是通過(guò)Dataset來(lái)隔離異構(gòu)的數(shù)據(jù)源，另一種是以流方式從數(shù)據(jù)源讀取(Data Reader方式)。傳統(tǒng)的應(yīng)用程序是通過(guò)先建立到數(shù)據(jù)庫(kù)的連接，在程序的整個(gè)運(yùn)行過(guò)程中維護(hù)連接的方式來(lái)設(shè)計(jì)的。ASP.NET采取了斷開(kāi)連接方式的數(shù)據(jù)結(jié)構(gòu)。當(dāng)瀏覽器向Web服務(wù)器請(qǐng)求網(wǎng)頁(yè)時(shí)，服務(wù)器處理這個(gè)請(qǐng)求，并將所請(qǐng)求的網(wǎng)頁(yè)發(fā)送給瀏覽器，然后連接就被斷開(kāi)，直到瀏覽器發(fā)出下一個(gè)請(qǐng)求。ADO.NET的另一個(gè)創(chuàng)新是引入了數(shù)據(jù)集(Dataset)。一個(gè)數(shù)據(jù)集是內(nèi)存中提供數(shù)據(jù)關(guān)系圖的高速緩沖區(qū)。數(shù)據(jù)集對(duì)數(shù)據(jù)源一無(wú)所知，它們可以由程序或通過(guò)從數(shù)
