Under the guidance of system engineering idea , and based on synthesizing the theory and methodology of agronomy , ecology , statistics and computer science , the multimedia agricultural information database including spatial data , attribute data , photograph data and net resource data was developed by widely collecting , and further standardizing and normalizing agricultural resource data , special data ( variety data , soil data , atmospheric data , and country economic information ) , and internet agricultural information . furthermore , by deeply and systematically studying the characteristics of all kinds of the system structures of the information management systems , and according to the design concept of software engineering , modularization and soft - component , the browser / server mode & web - based agricultural information management system ( waims ) with the functions of information collection , query , analysis , calculation , prediction and maintenance was developed by utilizing the net computer program language . by using the safe security technology of b / s mode based information system , a complete new role - based safe manipulating model of information system was introduced into the agricultural information management system to establish integrated function for safety control 在系統(tǒng)工程思想指導下,綜合應(yīng)用農(nóng)學、生態(tài)學、統(tǒng)計學以及計算機科學等學科的基本理論與方法,通過廣泛收集農(nóng)業(yè)資源信息數(shù)據(jù)、專題數(shù)據(jù)(如品種數(shù)據(jù)、土壤數(shù)據(jù)、氣象數(shù)據(jù)、農(nóng)村經(jīng)濟信息等)和internet網(wǎng)上農(nóng)業(yè)科技信息,并對這些信息進行標準化和規(guī)范化,建立包括屬性數(shù)據(jù)、圖片數(shù)據(jù)、網(wǎng)絡(luò)資源等在內(nèi)的多媒體農(nóng)業(yè)信息數(shù)據(jù)庫,進一步通過深入系統(tǒng)地研究信息管理系統(tǒng)的各種體系結(jié)構(gòu)的特點,按照軟件工程和模塊化和構(gòu)件化設(shè)計思想,使用網(wǎng)絡(luò)計算機編程語言,研制具備信息采網(wǎng)絡(luò)化農(nóng)業(yè)信息管理系統(tǒng)的構(gòu)建與實現(xiàn)集、查詢、分析、統(tǒng)計、預(yù)測、維護、輸出等設(shè)計功能的基于瀏覽器/服務(wù)器模式( b / s模式)的網(wǎng)絡(luò)化農(nóng)業(yè)信息管理系統(tǒng)( waims ) o4 .利用基于b / s模式的信息系統(tǒng)安全保障技術(shù)將一種全新的墓于角色的信息系統(tǒng)安全控制模型引入到農(nóng)業(yè)信息管理系統(tǒng)中,構(gòu)建了系統(tǒng)完整的安全控制功能,為農(nóng)業(yè)信息、管理系統(tǒng)的安全使用提供了有力保障。
