In addition, the paper designs a bottom database model, selects a multi - aim strategy combining files with known data, and establishes dual interaction data model that has explicit conceptual structure and directly aims to geographic objects, and provides backing up enquiry language ( g - sql ). simultaneously, after analyzing and studying methods available for the under pipelines, the paper constructs survey adjustment calculation model, and according to the model, checks the survey of under pipelines. the results indicate that the model is suitable to actual requirement because it greatly increase calculation speed, meeting calculation accuracy requirement
在此基礎上，對系統的底層數據模型進行設計，選擇了文件與成熟數據庫相結合的混合策略，併兼顧面向對象的數據庫（ oodb ）和可擴充數據庫（ edb ）的特點，建立了一個概念層次清晰、面向地理對象實體的雙層語義數據模型以及支持模型的查詢語言g - sql ，同時對地下管線的各種測試方法進行分析研究，建立了地下管線測量平差計算模型，並以此對所勘測的地下管線進行核算，計算結果表明，計算模型不僅大大提高了核算的速度，同時在計算精度上也符合核算的要求，是符合實際要求的關于測量平差計算的模型。 -
In the research of xml query language, we consider the requirement of two categories ( for data - centric and for document - centric ) of xml applications and point oat that the basic operations in xml - quey are pattem matching, selection and filtering, and result reconstfuction. the path expression and the flwr expression in xquery are typical structurs tha are comprised of these operations
在對xml查詢語言的研究中，從以文檔為中心和以數據為中心這兩類xml應用需求的分析出發，指出xml查詢的基本操作是模式匹配、選擇過濾和結果構造， xquery中路徑（包括簡單路徑和正規路徑）表達式和flwr表達式是進行這些操作的典型結構。 -
Using the sdl design language, the scheme is simulated and the result can meet the requirement of the high reliability for the data transfer in a mobile communication environment
作者利用sdl設計語言的模擬程序對該簡化方案進行了模擬，模擬結果基本滿足移動環境下的對數據傳輸的高質量要求。 -
According to the modern software engineering design idea, the systematical requirement for the construction of beijing eco - environment information was analyzed and studied. it was designed with uml ( unified modeling language ) and constructed under iterate development model as an internet network system using multi - language crossing flatforms technologies to integrate multi - source data. 2
按照現代軟體工程的設計思想，分析和研究北京市生態環境信息化建設的系統需求，提出以uml （統一模式語言）為設計模型，採用迭代式研發模式，以多種語言跨平臺技術集成多源數據，建立生態環境互聯系統的研發方案； 2 -
E ) because requirement analysis and design specification are always written in natural language, it is difficult to measure them. as uml is becoming a standard diagrammatic notation for object - oriented modeling and is spreading rapidly, it has been chosen to express the artifacts developed during the requirement analysis and system design stages. this dissertation proposes the uml based artifacts measurement method, analyzes their viewpoints and experimental data
）提出應用uml進行軟體需求和設計的度量方法，並設計和實現了一個基於uml的軟體需求分析和設計方案的度量工具，而且用實際軟體項目作為實例進行了運行實驗，並對其意義和度量結果數據進行了分析。
