Map layer , graphics edit , database view , database structure operation , information search etc can operate this system . this system have much functions , such as input attributes information , 通過本系統(tǒng)可進(jìn)行礦業(yè)權(quán)屬性信息的輸入、存貯、查詢、檢索、瀏覽顯示、輸出以及對空間信息的查詢分析功能。
In the deseign of above _ computer software , based the requirement analysis about the whole system , we determine the software deseign of monitoring system , such as function modules and database structure 在上位機(jī)軟件的設(shè)計(jì)中,根據(jù)軟件的需求分析與方案設(shè)計(jì),確定了監(jiān)控軟件的總體功能模塊和數(shù)據(jù)庫設(shè)計(jì)。
Next discusses in detail the whole system function especially the workstation function . then describes the whole database structure in detail , the design thought and the flow chart of main function 其次對整個系統(tǒng)所需要的數(shù)據(jù)庫結(jié)構(gòu)做了詳細(xì)敘述,同時分析了中心軟件中的主要功能模塊的設(shè)計(jì)思想以及實(shí)現(xiàn)流程。
Accomplished the design of database structure . according to requirement analyse of system security , the dissertation designed scheme of system security in order to realize de mand of system security 完成了數(shù)據(jù)庫結(jié)構(gòu)的設(shè)計(jì)。結(jié)合系統(tǒng)的安全性需求分析,有針對性地設(shè)計(jì)了系統(tǒng)的安全方案,以實(shí)現(xiàn)系統(tǒng)的安全性需求。
When designing a database structure , it is difficult do deal with records which have variety length . we should consider more on the structure if the database is mainly used in query 在進(jìn)行數(shù)據(jù)庫結(jié)構(gòu)設(shè)計(jì)時,對變長記錄的處理是一個難點(diǎn),而建立一個以查詢?yōu)橹鞯臄?shù)據(jù)庫考慮到查詢效率,在建庫時又要做許多特殊考慮。
The system is excellent at generalization , reliability and the design of functions so that it is easy to ppularize . this paper summarizes its design ideas in aspect of database structure , program modules , functions and nmning environment 本文從數(shù)據(jù)庫設(shè)計(jì)、系統(tǒng)模塊及功能設(shè)計(jì)和系統(tǒng)運(yùn)行環(huán)境三個方面概述了該系統(tǒng)的設(shè)計(jì)思想。
The whole design flow is analyzed , the database structure is described and the system function is introduced . some practical examples are given to show the capabilities of the approach in a series mechanical system 將本文提出的狀態(tài)變換矩陣方法應(yīng)用于生產(chǎn)實(shí)際中,進(jìn)行多個設(shè)計(jì)實(shí)例的可計(jì)算自動求解,實(shí)踐表明該方法可行、有效。
On the aspect of searching mechanism , the system optimizes searching from database structures as well as searching algorithm : the design of database structures standardizes to 3nf ; and searching system provides many search options 在查詢方面,系統(tǒng)從數(shù)據(jù)庫結(jié)構(gòu)和查詢算法兩個方面做了相應(yīng)的優(yōu)化:系統(tǒng)的數(shù)據(jù)庫設(shè)計(jì)按第3范式規(guī)范化。
