The two - level storage structure consists of basic information table of survey area and data table of survey spot , both of which is related by serial number of survey area 兩級(jí)存儲(chǔ)結(jié)構(gòu)為測(cè)區(qū)基本信息表和測(cè)點(diǎn)數(shù)據(jù)表,通過測(cè)區(qū)編號(hào)建立對(duì)應(yīng)關(guān)系。
1 . building aerial gamma - ray spectrometric database developed with sql server 2000 database management system , the entity - relation model of aerial gamma - ray spectrometric database is designed . a two - level storage structure is adopted to store aerial gamma - ray spectrometric survey data so as to shorten data rebundancy maxmimumly 建立航空伽瑪能譜數(shù)據(jù)庫(kù)以sqlserver2000數(shù)據(jù)庫(kù)管理系統(tǒng)為開發(fā)平臺(tái),設(shè)計(jì)了航空伽瑪能譜數(shù)據(jù)庫(kù)的實(shí)體?關(guān)系模型,采用兩級(jí)存儲(chǔ)結(jié)構(gòu)來存儲(chǔ)航空伽瑪能譜測(cè)量數(shù)據(jù),最大限度地降低了數(shù)據(jù)冗余度。
