【正文】 ong as can the accurate expression data attribute. The accurate expression data meaning is the biggest advantage which XML brings. Moreover, the XML use text mode saves its form, is advantageous for between the procedure, the operating system links up, the exchange, the adapt ion at present the Inter development. XML appeared the short several years to obtain the widespread application, at present newly promotes software nearly could support XML. For example Microsoft Net series software, Office series software and so on. Does not leave for several years, XML can replace HTML to bee on Inter the standard mark language? This system if introduces the XML language expression data the advantage, is causes in the system the customer end data demonstration and the system processing data separation, reduces the development system plex, reduces the system process time, reduces the work transmission quantity, thus enhances the system to carry out the efficiency. The unified modeling language (Unified Modeling Language, UML) is the objectoriented software standardized modeling language. Because its simple, is unified, also can express in the software design the tendency and the static information, at present already became the visible modeling language in fact industry standard. From enterprise information system to base on Web distributional application, even is strict realtime inserts the type system all suitably to e in handy UML to e the modeling. This is one kind of rich expression strength language, may describe each kind of view which the development needs, then take this as foundation assembly system. This system if introduces UML the main superiority enhances the software development efficiency, reduces the development time, saves the development cost. Take the UML language modeling should be by Rational Corporation39。 也可以設(shè)置以下幾項： 中北大學(xué) 2020 屆畢業(yè)設(shè)計英文文獻譯文 第 2頁 共 4頁考試工作站：對考生進行考試的客戶端程序。 當(dāng)前軟件界比較流行的系統(tǒng)結(jié)構(gòu)模型主要有： C/S 結(jié)構(gòu)模型與 B/S 結(jié)構(gòu)模型。另外， XML 使用文本方式存儲其格式，便于程序之間、操作系統(tǒng)之間溝通、交流，適應(yīng)目前互聯(lián)網(wǎng)的發(fā)展。 Borland 公司出品的 ModelMaker建模工具不僅支持 UML，而且在對象建模上也有其獨到的地方。 數(shù)據(jù)層：主要為事務(wù)邏輯層提供數(shù)據(jù)服務(wù)，如存儲數(shù)據(jù)操作結(jié)果、返回數(shù)據(jù)檢索結(jié)果等。 2）將服務(wù)器（包括應(yīng)用服務(wù)器、數(shù)據(jù)庫服務(wù)器與 Web 服務(wù)器）的硬盤分區(qū)轉(zhuǎn)化為 NTFS 格式，根據(jù)不同的需求為用戶開設(shè)各自的權(quán)限。 另外為保證考試的公平、公正，試卷的試題由計算機隨機從題庫抽取。s all functions, but also may carry on the verification question bank (only has verified question bank only then to be allowed to carry on test),establishment operation and so on test time, inquiry, printing test result. Also may establish following several items: Test workstation: Carries on the test to the examinee the customer end procedure. Mainly provided has carried on according to the system disposition stochastically sets the topic of a position, the confirmation registers, test function and so on time prompt, automatic judgment result, examination test result as well as standard answer. Test workstation divides into the customer end procedure and the Web way in the realization way, former allows the examinee (support touches screen test pattern) through the customer end procedure the way to carry on the test, latter allows the examinee to carry on the test through the test specialpurpose work. The test establishes the workstation: Carries on the establishment tote test service the customer end procedure. Mainly provided the revision question bank, the verification question bank, revised the examinee material, establ
