AS 或者StrNine WebStar上運(yùn)行。多個(gè)servelt還可以共享數(shù)據(jù)，從而易于實(shí)現(xiàn)數(shù)據(jù)庫(kù)連接共享和類似的資源共享優(yōu)化。最后，當(dāng)CGI程序結(jié)束對(duì)請(qǐng)求的處理之后，程序結(jié)束。但在實(shí)踐中，servelt的這種用法尚不流行，在此，我們只論述HTTP Servlet。如果數(shù)據(jù)存儲(chǔ)在數(shù)據(jù)庫(kù)中，那么，即使客戶端使用動(dòng)態(tài)Web內(nèi)容，比如applet，我們依舊需要執(zhí)行服務(wù)器端處理。兩種輸入都可用來構(gòu)建輸出頁面。同樣，兩種數(shù)據(jù)對(duì)開發(fā)來說都式至關(guān)重要的。對(duì)應(yīng)大多數(shù)其他應(yīng)用重慶三峽學(xué)院畢業(yè)設(shè)計(jì)外文翻譯[肖偉]網(wǎng)上購(gòu)物系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn)程序，也存在類似的問題。，但實(shí)際上從客戶端傳送到Web服務(wù)器的數(shù)據(jù)有兩種，它們分別為用戶在表單中輸入的顯式數(shù)據(jù)，以及后臺(tái)的HTTP信息。 Server 2008壓縮了輸出的日志流，以便使數(shù)據(jù)庫(kù)鏡像所要求的網(wǎng)絡(luò)帶寬達(dá)到最小。SQL Server 2008具有像服務(wù)器中加強(qiáng)的審查的配置和管理這樣的功能，這使得公司可以滿足各種規(guī)范需求。進(jìn)行加密使公司可以滿足遵守規(guī)范和及其關(guān)注數(shù)據(jù)隱私的要求。數(shù)據(jù)平臺(tái)愿景提供了一個(gè)解決方案來滿足這些需求，這個(gè)解決方案就是公司可以使用存儲(chǔ)和管理許多數(shù)據(jù)類型，包括 XML、、時(shí)間/日歷、文件、文檔、地理等等，同時(shí)提供一個(gè)豐富的服務(wù)集合來與數(shù)據(jù)交互作用：搜索、查詢、數(shù)據(jù)分析、報(bào)表、數(shù)據(jù)整合，和強(qiáng)大的同步功能。微軟 SQL Server 2008 SQL Server 2008是一個(gè)重大的產(chǎn)品版本，它推出了許多新的特性和關(guān)鍵的改進(jìn)，使得它成為至今為止的最強(qiáng)大和最全面的SQL Server版本。SQL Server 2000是Microsoft公司推出SQL Server數(shù)據(jù)庫(kù)管理系統(tǒng)，該版本繼承SQL Server ,可跨越從運(yùn)行 Microsoft
