( 2 ) aiming at the requirement of safe storage of the electronic documents on the information integrated platform in manufacturing enterprise , using encryption / decryption and compression / uncompression techniques and saving the electronic documents as some special attribute object of large database and managing the enterprise electronic documents effectively through database , a safe access mechanism of functional grant < wp = 7 > and recommendatory grant to decrease grant management maintenance cost is proposed and the storage mechanism of special database attribute object is studied and the method for saving , accessing and retrieving electronic document quickly is constructed . thus these methods can make the electronic documents of information integrated platform in manufacturing enterprises get safe , reliable and quick access . ( 3 ) according to this circumstance in which web pages are selected as the user interface of manufacturing application system , the safe measures of access control over web page resources are provided ( 2 )針對制造企業(yè)信息集成平臺中電子文檔安全存儲要求,采用加密和壓縮技術(shù),將電子文檔作為大型數(shù)據(jù)庫中某種特殊屬性對象來存儲,以數(shù)據(jù)庫方式對企業(yè)電子文檔進行集成的、統(tǒng)一的管理,提出一種訪問控制的增強型安全設(shè)計原則,基于此原則建立了管理授權(quán)和推薦式授權(quán)的安全訪問機制,用以提高系統(tǒng)的訪問安全性,并大大減少授權(quán)管理維護量;研究了特殊屬性對象的數(shù)據(jù)庫存儲機理,從而構(gòu)造一種快速存儲、訪問和檢索電子文檔的方法,使得企業(yè)信息集成平臺的電子文檔獲得安全、可靠、快速的訪問。
