Secondly , on the basis principles of mis and erp , combining the design and development of the management information system of the industrial company of green hill in chongqing ( qsmis ) , basing the foundations of system and demands analyzing , it carried on more detailed argumentations of module designing , data system , network and structure of system , modes of calculation etc . especially , it gave the discussing about flow rebuilding , technology of coding , interface designing , and system optimizing . at the same time , it expatiated the safety precautions of system , and explained the main ability and effects of system by the overall frames and charts of system ' s structure , and every logic flow chart of module of function of qsmis briefly 其次,在充分理解mis和erp原理基礎上,結合重慶青山工業公司管理信息系統( qsmis )的設計和開發,在系統需求分析的基礎上,對系統的功能模塊、數據庫系統、網絡拓撲及體系結構、計算模式等進行了較詳細的論述;尤其是對系統開發中實施的業務流程再造、編碼技術、界面設計、及系統優化等關鍵技術進行了較為系統的探討,同時對系統所實施的安全策略進行了闡述;并通過設計出的qsmis的總體框架以及系統結構圖、各功能模塊的邏輯流程圖,對系統實現的主要功能和作用作了簡要概述。
