mis開發(fā)模式的策略的分析(文件)
【正文】 w appear Intranet version of the OLAP tools are not mature enough, should have some kind of petition, and even to mature process, but it must be applied to a variety of database and user demand is more plex. But doing so greater investment and requires special training.(3) 在Intranet平臺(tái)中提供訪問關(guān)系數(shù)據(jù)庫的通用接口工具，這是最理想的做法，但目前產(chǎn)品仍沒有達(dá)到前兩種工具的性能，希望盡早有一個(gè)功能強(qiáng)的通用接口工具產(chǎn)生(3) in the Intranet platform to provide access to relational database generic interface tools, this is the most ideal, but the product still not reached before the performance of the two tools, hope to have a functional tool of mon interface。但目前出現(xiàn)的OLAP工具的Intranet版本都不夠成熟，應(yīng)有一番競(jìng)爭(zhēng)乃至到成熟的過程，但必須應(yīng)用于多種數(shù)據(jù)庫及需求比較復(fù)雜的用戶。這些方案的特點(diǎn)是基于各自的專有技術(shù)，與其數(shù)據(jù)庫產(chǎn)品以及開發(fā)工具緊緊地捆綁在一起。Intranet技術(shù)在這方面是無可比擬的。Under the traditional C/S has accumulated a large number of applications and information, such as various types of database and the various formats of files, and Intranet must be able to make the fullest use of these existing applications and information. Intranet technology base due to its generality, provides a standard interface is few and far between. Way to access the database in the final analysis is still the CGI, for example, and directly with CGI programming not only trouble, and maintenance more difficult, for the vast majority of the enterprise is not applicable, at least not enough to use, but also have a series of application interface tools. And B/S mode is currently only applies to information release, for such as online transaction processing (OLTP) applications there are substantial difficulties. So, C/S and B/S mode will coexist for a long time, and the interface between the two tools is also a kind of longterm demand. 全文檢索數(shù)據(jù)庫的集成 fulltext retrieval database integrationInternet的技術(shù)就是以文本為基礎(chǔ)的，可以說，Hypertext就說明了這個(gè)優(yōu)點(diǎn)。Intranet技術(shù)基礎(chǔ)由于其通用性，能提供的標(biāo)準(zhǔn)接口是不多的。(3) the application server run data load is heavier.由于B/S架構(gòu)管理軟件只安裝在服務(wù)器端（Server）上，網(wǎng)絡(luò)管理人員只需要管理服務(wù)器就行了，用戶界面主要事務(wù)邏輯在服務(wù)器（Server）端完全通過WWW瀏覽器實(shí)現(xiàn)，極少部分事務(wù)邏輯在前端（BrBecause only a B/S structure management software is installed on the Server (Server), network managers just need to manage the Server, the user interface for the main business logic on the Server (Server) side pletely through the WWW browser implementations, few transaction logic in the frontend (Browser）實(shí)現(xiàn)，所有的客戶端只有瀏覽器，網(wǎng)絡(luò)管理人員只需要做硬件維護(hù)。For example many people sina on the net every day, as long as the installation of the browser is ok, don39。(2) cost reduction, more choice.大家都知道windows在桌面電腦上幾乎一統(tǒng)天下，瀏覽器成為了標(biāo)準(zhǔn)配置，但在服務(wù)器操作系統(tǒng)上windows并不是處于絕對(duì)的統(tǒng)治地位。因此，維護(hù)和升級(jí)革命的方式是“瘦”客戶機(jī)，“胖”服務(wù)器。對(duì)一個(gè)稍微大一點(diǎn)單位來說，系統(tǒng)管理人員如果需要在幾百甚至上千部電腦之間來回奔跑，效率和工作量是可想而知的，但B/S架構(gòu)的軟件只需要管理服務(wù)器就行了，所有的客戶端只是瀏覽器，根本不需要做任何的維護(hù)。在JAVA這樣的跨平臺(tái)語言出現(xiàn)之后，B/S架構(gòu)更是猛烈沖擊C/S，并對(duì)其形成威脅和挑戰(zhàn)。s access, Numbers can be repeated, must have the customer to establish the orderSuch a rule. All of these, to end users on the work at the front desk program is transparent, they don39。所有這些，對(duì)于工作在前臺(tái)程序上的最終用戶，是“透明”的，他們無須過問（通常也無法干涉）背后的過程，就可以完成自己的一切工作。The simplest database application of C/S architecture consists of two parts, namely the client application and database server program. The process of is called the front desk and the background process. Run the database server machine, also known as the application server. Once the
