dada model

基本解釋

The topology was represented with scheme-tree and adjacency list in the new model with dada saved in the database, so that data redundancy had greatly reduced and evolution was depict distinctly.
該模型用方案樹與鄰接表描述動態(tài)路網(wǎng)的拓撲結構，用數(shù)據(jù)庫存儲路網(wǎng)數(shù)據(jù)，達到了盡可能減少數(shù)據(jù)冗余度并有效揭示動態(tài)性的目的。
These models can be extended relational model, object oriented model and other special data models. These models show high ability of dada modeling on complex data in engineering application area.
這些數(shù)據(jù)模型或對傳統(tǒng)的關系模型進行擴展，或采用面向對象模型以及其它各類專用的數(shù)據(jù)模型，在工程應用領域中顯示出強大的威力。
With the theoretical analysis and experiment dada of document, the engineering model of rod dispersing velocity and angel is build.
在理論分析的基礎上，建立了桿條群速度及角度散布參數(shù)預估的工程分析模型。
