It was researched the development of database subsystem of ws9 aero engine computer aided - testing in this paper 本文主要討論了ws9發(fā)動(dòng)機(jī)試車計(jì)算機(jī)輔助試驗(yàn)( thecomputeraided - testingcat )系統(tǒng)數(shù)據(jù)庫子系統(tǒng)的開發(fā)工作。
On the base of investigating the requirement of database subsystem , the paper researched how to design the concept model > logic model and physics model of cat system engineer database 在詳細(xì)進(jìn)行數(shù)據(jù)庫子系統(tǒng)需求關(guān)系調(diào)研的基礎(chǔ)上,用系統(tǒng)工程的理論研究了cat系統(tǒng)工程數(shù)據(jù)庫的概念模型、邏輯模型和物理模型的設(shè)計(jì)。
The knowledge of cctdes is expressed with vfp6 . 0 database . such database subsystems are developed as cocoon material , water quality condition , disadvantages of cocoon cooking , and facility of factory , raw silk classification standard , as well as technological designing subsystem 知識(shí)的表示采用vfp6 . 0數(shù)據(jù)庫技術(shù),在認(rèn)真選取字段,優(yōu)化數(shù)據(jù)庫結(jié)構(gòu)的基礎(chǔ)上,開發(fā)出繭質(zhì)資料、水質(zhì)條件、煮繭弊病分析、工廠設(shè)備以及生絲分級(jí)標(biāo)準(zhǔn)等數(shù)據(jù)庫子系統(tǒng)和工藝設(shè)計(jì)子系統(tǒng)。
The paper uses the romc method to analyse the claimed train approval optimization dss specifically . according to the peculiarity of the system , the paper uses the archetype method to design and develop the system , and design database subsystem , mb subsystem , kb subsystem in detail based on the giving the whole structure and the system structure 本文利用romc方法對(duì)鐵路請(qǐng)求車審批輔助決策系統(tǒng)進(jìn)行了詳細(xì)的分析,基于本系統(tǒng)的特點(diǎn),采用了原型法對(duì)系統(tǒng)進(jìn)行了設(shè)計(jì)和開發(fā),并在給出系統(tǒng)總體結(jié)構(gòu)、系統(tǒng)體系結(jié)構(gòu)的基礎(chǔ)上,相應(yīng)進(jìn)行了數(shù)據(jù)庫系統(tǒng)、模型庫系統(tǒng)、知識(shí)庫系統(tǒng)各個(gè)子系統(tǒng)的詳細(xì)設(shè)計(jì)。
Taking the project management of an aviation factory as our study object , and based on the consideration of current actuality of project management , a proposal of designing project management system on distributed groupware platform is put forward , which can improve system expandability and reusability . then , a structure of the database subsystem and a model of the whole system is described . finally , some proposals for system optimization is also presented 本文從應(yīng)用角度出發(fā),以某航空主機(jī)廠項(xiàng)目管理為應(yīng)用對(duì)象,結(jié)合當(dāng)前項(xiàng)目管理的實(shí)際,為提高項(xiàng)目管理系統(tǒng)的先進(jìn)性和可擴(kuò)展性,提出了建立基于分布式組件技術(shù)項(xiàng)目管理系統(tǒng)的構(gòu)想,并設(shè)計(jì)了基于分布式組件技術(shù)的項(xiàng)目管理軟件的數(shù)據(jù)庫系統(tǒng)結(jié)構(gòu)和軟件系統(tǒng)模型,完成了軟件原型開發(fā),對(duì)系統(tǒng)的進(jìn)一步完善和優(yōu)化提出了建議。
