1、SQL Server是由Microsoft開發(fā)和推廣的關(guān)系數(shù)據(jù)庫系統(tǒng)(DBMS),它最初是由Microsoft、Sybase和Ashton-Tate三家公司共同開發(fā)的,并于1988年推出了第一個OS/2版本。
2、關(guān)系數(shù)據(jù)庫(RDBMS)管理系統(tǒng)功能:
》維護數(shù)據(jù)庫數(shù)據(jù)之間的關(guān)系;
》保證數(shù)據(jù)存儲的正確性;
》當(dāng)出現(xiàn)系統(tǒng)故障的時候,將所有數(shù)據(jù)恢復(fù)到能夠保證一致行的某種狀態(tài)
3、RDBMS:SQL Server,Oracle,DB/2,Sybase,Informix
4、Non-RDBMS(File-based):Foxpro,Access
二、SQL Server 2000的版本
1、SQL Server 2000常見版本有:
》企業(yè)版(Enterprise Edition)
支持所有SQL Server 2000的功能。該版本多用于大中型產(chǎn)品數(shù)據(jù)庫服務(wù)器,并且可以支持大型網(wǎng)站,企業(yè)OLTP(聯(lián)機事務(wù)處理)和大型數(shù)據(jù)倉庫系統(tǒng)OLAP(聯(lián)機分析處理)所要求的性能。
》標(biāo)準版(Standard Edition)
實用范圍是小型的工作組或部門。它支持大多數(shù)的SQL Server2000功能。但是,不具有支持大型數(shù)據(jù)庫,數(shù)據(jù)倉庫和網(wǎng)站的功能。而且,不支持所有的關(guān)系數(shù)據(jù)庫引擎的功能。
》個人版(Personal Edition)
主要適用于移動用戶,因為他們經(jīng)常從網(wǎng)絡(luò)上斷開,而運行的應(yīng)用程序卻仍然需要SQL Server 2000的支持。除了事務(wù)處理復(fù)制功能以外,能夠支持所有SQL Server 2000標(biāo)準版支持的特性。
》開發(fā)者版(Developer Edition)
適用于應(yīng)用程序開發(fā)的版本,支持除圖形化語言設(shè)置以外的SQL Server2000的所有其它功能。該版本主要適用于程序員在開發(fā)應(yīng)用程序時,將SQL Server 2000作為其數(shù)據(jù)存儲區(qū)。雖然開發(fā)版的功能齊備,但是只被授權(quán)為一個開發(fā)和測試系統(tǒng),而不是一個產(chǎn)品服務(wù)器。
1.1 SQL Server特點
》與因特網(wǎng)的集成:
SQL Server 2000的數(shù)據(jù)庫引擎全面支持XML(Extensive Markup Language,擴展標(biāo)記語言),能使用戶很容易地將數(shù)據(jù)庫中的數(shù)據(jù)發(fā)布到Web頁面上。
》可伸縮性與可用性:
可跨越從運行Windows 95/98的膝上型電腦到運行Windows 2000的大型多處理器等多種平臺使用。另外,對聯(lián)合服務(wù)器,索引視圖等的支持,使得SQL Server 2000企業(yè)版可以升級到最大Web站點所需的性能級別。
》企業(yè)級數(shù)據(jù)庫功能:
SQL Server 2000分布式查詢可以引用來自不同數(shù)據(jù)庫的數(shù)據(jù),而且這些對于用戶來說是完全透明的;分布式數(shù)據(jù)庫將保證任何分布式數(shù)據(jù)更新時的完整性;復(fù)制可以使我們能夠維護多個數(shù)據(jù)復(fù)本,這些用戶能夠自主地進行工作,然后再將所做的修改合并到發(fā)布數(shù)據(jù)庫;SQL Server 2000關(guān)系數(shù)據(jù)庫引擎能夠充分保護數(shù)據(jù)完整性,還可以將管理并發(fā)修改數(shù)據(jù)庫開銷到最小。
》易于安裝,部署和使用:
SQL Server 2000由一系列的管理和開發(fā)工具組成,這些工具使得在多個站點上進行SQL Server的安裝,部署,管理和使用變得更加容易。開發(fā)人員可以更加快速地交付SQL Server應(yīng)用程序,而且只需要進行最少的安裝和管理就可以實現(xiàn)這些應(yīng)用程序。
》數(shù)據(jù)倉庫:
數(shù)據(jù)倉庫是SQL Server 2000中包含的用于分析取和分析匯總數(shù)據(jù)以進行聯(lián)機分析處理的工具。這個功能只在Oracle和其他更昂貴的DBMS中才有。
1.1.1 SQL Server 2000新特性
全面擴展了SQL Server 7.0的性能,可靠性和易用性。增加了一系列的功能,具體如下:
》在關(guān)系數(shù)據(jù)庫方面的增強
》圖形管理增強
》增強的聯(lián)合數(shù)據(jù)庫服務(wù)器
1.2 SQL Server 2000工具和實用程序
1、企業(yè)管理器 2、服務(wù)管理器 3、查詢分析器 4、事件探查器
5、導(dǎo)入和導(dǎo)出數(shù)據(jù) 6、服務(wù)器網(wǎng)絡(luò)使用工具 7、客戶端網(wǎng)絡(luò)使用工具 8、聯(lián)機幫助文檔
1.2.1 企業(yè)管理器
企業(yè)管理器是基于一種新的被稱為微軟管理控制臺(Microsoft Management Console)的公共服務(wù)器管理環(huán)境,它是SQL Server 2000中最重要的一個管理工具。
企業(yè)管理器不僅能夠配置系統(tǒng)環(huán)境和管理SQL Server,而且由于它能夠以層疊列表的形式來顯示所有的SQL Server對象,因而所有SQL Server對象的建立與管理都可以通過它來完成。
用企業(yè)管理可以完成的操作
》管理SQL Server服務(wù)器;建立與管理數(shù)據(jù)庫;建立與管理表、視圖、存儲過程、觸發(fā)程序、角色、規(guī)則、默認值等數(shù)據(jù)庫對象,以及用戶定義的數(shù)據(jù)類型;備份數(shù)據(jù)庫和事務(wù)日志、
恢復(fù)數(shù)據(jù)庫;復(fù)制數(shù)據(jù)庫;設(shè)置任務(wù)調(diào)度;設(shè)置警報;提供跨服務(wù)器的拖放控制操作;管理用戶賬戶;建立Transact-SQL命令語句以及管理和控制SQL Mail。
》在企業(yè)管理器中包含兩個窗口,左側(cè)的窗口是以“樹狀目錄”顯示的活動窗口,右側(cè)是顯示內(nèi)容的窗口。

SQL是英文Structured Query Language的縮寫,意思為結(jié)構(gòu)化查詢語言。我們大多讀他的縮寫就是sql。直接讀SQL(瑟我)
WWW是環(huán)球信息網(wǎng)(World Wide Web )的縮寫,也可以簡稱為Web,中文名字為“萬維網(wǎng)”。 當(dāng)你想進入萬維網(wǎng)上一個網(wǎng)頁, 或者其他網(wǎng)絡(luò)資源的時候,通常你要首先在你的瀏覽器上鍵入你想訪問網(wǎng)頁的統(tǒng)一資源定位符(Uniform Resource Locator),縮寫URL,或者通過超鏈接方式鏈接到那個網(wǎng)頁或網(wǎng)絡(luò)資源。這之后的工作首先是URL的服務(wù)器名部分,被名為域名系統(tǒng)的分布于全球的因特網(wǎng)數(shù)據(jù)庫解析,并根據(jù)解析結(jié)果決定進入哪一個IP地址(IP address)。 接下來的步驟是為所要訪問的網(wǎng)頁,向在那個IP地址工作的服務(wù)器發(fā)送一個HTTP請求。在通常情況下,HTML文本、圖片和構(gòu)成該網(wǎng)頁的一切其他文件很快會被逐一請求并發(fā)送回用戶。 網(wǎng)絡(luò)瀏覽器接下來的工作是把HTML、CSS和其他接受到的文件所描述的內(nèi)容,加上圖像、鏈接和其他必須的資源,顯示給用戶。這些就構(gòu)成了你所看到的“網(wǎng)頁”。
