| 基于網(wǎng)絡(luò)數(shù)據(jù)庫的列車運(yùn)行圖體系結(jié)構(gòu)研究(24 卷) |
| 英文標(biāo)題 |
| Structural Study on Train Graph System that is Based on Network Database |
| 摘要 |
| 通過對(duì)列車運(yùn)行圖系統(tǒng)的體系結(jié)構(gòu)進(jìn)行研究，提出列車運(yùn)行圖編制系統(tǒng)應(yīng)采用服務(wù)器的三層體系結(jié)構(gòu)和基于分布式的數(shù)據(jù)庫體系結(jié)構(gòu)，并結(jié)合基于對(duì)象——關(guān)系模型的ORACLE數(shù)據(jù)庫管理系統(tǒng)對(duì)數(shù)據(jù)訪問方式進(jìn)行了探討。 |
