This article starts with and dissertate these key technologies such as middle component, multimedia large object, connection and snap shop of database, data transactions of distributed databases, data security issue in distributed databases, data backup and recovery of databases and data audit in detail . the discussion would be done combining with some practical projects and previously developed systems from the software engineering point of view and achieve research results which had been applied and validated in the projects and systems 所以本文從這幾個關(guān)鍵技術(shù)入手,從軟件工程的角度出發(fā),結(jié)合多個實際項目和以前開發(fā)的系統(tǒng)為基礎(chǔ),從系統(tǒng)設(shè)計的基本思想、思路出發(fā),結(jié)合一些基本依據(jù)分別以組件中間件、多媒體大數(shù)據(jù)對象、數(shù)據(jù)庫的鏈接與快照、分布式數(shù)據(jù)庫數(shù)據(jù)的處理、分布式數(shù)據(jù)庫數(shù)據(jù)的安全問題、數(shù)據(jù)庫的備份和恢復(fù)以及數(shù)據(jù)審計等具體問題進行比較詳細(xì)的論述,并且將得到研究結(jié)果在項目和系統(tǒng)中予以實現(xiàn)加以驗證。
In order to solve the problem that it is unable to control the storage of yarn and that in yarn factory as manual management, this paper designs a yarn manangement system for knitting dress enterprises with the fast and accurate information transmission of computer . the system realizes the addition, cancellation, amendment, inquiry and data auditing functions on the basis of user's security and limits of authority, and also provides the statistics and printing function, satisfying user's demand 針對手工操作管理紗線無法及時準(zhǔn)確掌握紗線庫存以及在織造廠的紗線存量情況,利用計算機信息傳播的快速性和準(zhǔn)確性,設(shè)計實現(xiàn)了針織服裝企業(yè)紗線管理系統(tǒng),該系統(tǒng)在實現(xiàn)了用戶安全與權(quán)限認(rèn)證的基礎(chǔ)上完成了數(shù)據(jù)的增、刪、改、查詢和單據(jù)審核等功能,滿足了用戶需求。
