⑹ 新聞錄入和修改:注冊用戶錄入一條新聞所需要的內(nèi)容,包含標(biāo)題、關(guān)鍵字、類型、來源部門、發(fā)布日期等,同時從登錄模塊得到用戶名,這些信息將被寫入數(shù)據(jù)庫中保存。 ⑶ 新聞閱讀:在其他頁面中點擊標(biāo)題鏈接即進(jìn)入新聞閱讀頁面,此時,每條新聞的詳細(xì)信息將被取出,包括內(nèi)容、標(biāo)題、關(guān)鍵字等,并按照相對固定的格式放置在頁面的不同區(qū)域,所有新聞使用大致相同的頁面布局,只是各字段對應(yīng)的內(nèi)容不同而已,另外,頁面其它位置,可以動態(tài)放置其他元件,如網(wǎng)站標(biāo)志 logo、頁面廣告 banner 等鏈接圖片,這樣可以很容易地實現(xiàn)圖文并茂的閱讀效果。 ( 3)功能完善:包括常見網(wǎng)站 的新聞管理的各個方面:新聞錄入、瀏覽、刪除、修改、檢索等各個方面,完整地實現(xiàn)了網(wǎng)站對即時新聞的管理要求。其工作流程為:用戶登錄通過權(quán)限判斷,普通用戶只能瀏覽、閱讀和查詢新聞, 注冊用戶除了可以完成普通用戶的操作外,還可以進(jìn)入新聞管理模塊進(jìn)行新聞錄入、修改和刪除的操作。數(shù)據(jù)集對數(shù)據(jù)源一無所知,它們可以由程序或通過從數(shù)據(jù)倉庫中調(diào)入數(shù)據(jù)而被生 成、填充。 采取了斷開連接方式的數(shù)據(jù)結(jié)構(gòu)。 訪問數(shù)據(jù)庫的原理 與數(shù)據(jù)庫相連, 提供了如下 3 種方式:通過 ODBC 相連;通過 OLEDB 相連;直接與 SQL Server相連。 業(yè)務(wù)邏輯層負(fù)責(zé)接收瀏覽器傳來的請求并將請求傳給數(shù)據(jù)層,同時將請求處理結(jié)果發(fā)給瀏覽器。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)用程序的運行就可以更新應(yīng)用文件。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 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 頁面每次打開都必須經(jīng)過先編譯后解釋的過程,所以頁面在反復(fù)打開時速度沒有任何提升,而 頁面只需要一次編譯后不需要重新編譯,直到該頁面被 修改或 Web 應(yīng)用程序重新啟動。 【關(guān)鍵詞】 新聞 管理 數(shù)據(jù)庫 隨著 Inter 的普及,越來越多的企業(yè)建立了自己的 WWW 網(wǎng)站,企業(yè)通過網(wǎng)站可以展示產(chǎn)品,發(fā)布最新動態(tài),與用戶進(jìn)行交流和溝通,與合作伙伴建立聯(lián)系,以及開展電子商務(wù)等。 Direct and SQL Server is connected. 3 ways as a result of theapplication level difference, cause the efficiency from lowly toarrive high, independence from Gao Daodi. Regarding connected databasedata processing, also some 2 ways, namely one kind is isolates theisomerism through DataSet the data pool, another kind is by flows theway to read from the data pool takes (the DataReader way). The traditional application procedure is through first establishes thedatabase the connection, maintains the connection in the procedureentire movement process the way to design. has adopted theseparation connection way construction of data. When browser to Webserver request homepage, the server processes this request, andrequested the homepage transmission for the browser, then theconnection is separated, sends out the next request until thebrowser. The another innovation was has introduced the data set(Dataset). A data set is in the memory provides the data relationschart the high speed buffer. The data set knows nothing about to thedata pool, they may or through call in the data by the procedure fromthe data warehouse to produce, the packing. No matter the data fromwhere gain, the data set all is operated through the use similarprocedure template, and it uses the same latent data buffer. 2 systems functional designs systems function structures This news management system management system may operatingsystem platform move in Windows in 2,000 Server, the Web server isIIS, the database server is Microsoft SQL Server2020, Microsoft VisualStudio which the development kit uses NET and DreamWeaver. Chart 2produces the system the function structure drawing. Its work flow is:The user registers through the jurisdiction judgement, the averageconsumer only can glance over, rea
