jsp基于Web的可維護的數(shù)據(jù)庫瀏覽器(源代碼+論文+答辯PPT),jsp,基于,Web,維護,數(shù)據(jù)庫,瀏覽器,源代碼,論文,答辯,PPT 摘要 可維護的數(shù)據(jù)庫瀏覽器，采用基于Web的多層應(yīng)用模型。程序上采用MVC結(jié)構(gòu)，可以將數(shù)據(jù)存取邏輯與數(shù)據(jù)表現(xiàn)邏輯分開，組合JSP Servlet和JavaBean來建造靈活與可維護的應(yīng)用程序的設(shè)計模式。 Web界面的要求是允許用戶瀏覽相關(guān)數(shù)據(jù)庫中的內(nèi)容.該界面使用戶可以通過指定一個JDBC驅(qū)動器或URL來與一個數(shù)據(jù)庫連接。接著，應(yīng)用程序會允許用戶瀏覽數(shù)據(jù)庫中定義的所有表，并且可以選擇任何一個表對其數(shù)據(jù)進行處理。同樣，用戶還可以輸入SQL查詢語句并查看這些查詢操作產(chǎn)生的列表數(shù)據(jù)。在用戶使用會話的任何時間內(nèi)，必須確保用戶可以很容易地斷開數(shù)據(jù)庫，并連接到另一個數(shù)據(jù)庫上。 關(guān)鍵字：MVC、設(shè)計模式、多層結(jié)構(gòu)。 Abstract The data base browser that can be maintained, adopts the multilevel application model based on Web, Procedure adopt MVC structure, can deposit and withdraw data logic separate from that the data display logic, Come to build flexibly with the design mode of the application program that can be maintained. Web request of interface to allow user content to have a look around relevant data base. Interface this make user can connect through appointed one JDBC driver or URL with a data base. Then, the application program will allow users to have a look around all forms defined in the data base , And can choose any form to deal with its datum . Equally, user can also input SQL inquire the sentence and look over that these are inquired about and operate the tabular data produced . Until what user use conversation any time, must guarantee user can disconnection data base very easily, And connect to another data base . Keyword: MVC Design the mode Multilevel structure. 2
