【摘要】：為系統(tǒng)管理黃河流域水資源調(diào)配決策支持系統(tǒng)的數(shù)據(jù),開發(fā)了基于Oracle 10g的數(shù)據(jù)庫。按照各個模塊的模型庫對數(shù)據(jù)屬性的不同需求將數(shù)據(jù)庫進行分類化開發(fā)。按照決策支持系統(tǒng)對數(shù)據(jù)庫的要求將總體結(jié)構(gòu)分層。針對開發(fā)過程中面臨的問題,開發(fā)了聯(lián)動管理與接口技術、基于角色的多用戶模式,引入了包括視圖與數(shù)據(jù)備份的安全機制。應用表明,本數(shù)據(jù)庫讀寫效率高,安全性好,方便管理,滿足了不同類型的用戶對數(shù)據(jù)庫的訪問與操作要求,為黃河流域水資源監(jiān)控能力建設的數(shù)字化提供了技術支撐。
[Abstract]:In order to manage the data of the decision support system for water resources allocation in the Yellow River Basin, a database based on Oracle 10g was developed. The database is classified and developed according to the different requirements of the model base of each module. The overall structure is stratified according to the database requirements of the decision support system (DSS). Aiming at the problems in the development process, the technology of linkage management and interface is developed. The multi-user model based on role is introduced, and the security mechanism including view and data backup is introduced. The application shows that the database has high reading and writing efficiency, good security and convenient management, which meets the requirements of different users to access and operate the database, and provides technical support for the digitization of water resources monitoring capacity construction in the Yellow River Basin.
