数据依赖关系 meaning in English
artificial data dependency
Examples
- Association rules is an effective method for describing the dependency relations in data , and it is one of the improtant aspects of knowledge discovery
关联规则是数据依赖关系的有效描述方法，是数据挖掘研究的重要内容。 - The research of line is belonged to system frame and running mechanism of vxi _ bus test software platform . being one of two programming element , the line plays an important role in software platform . it shows the connection and control relation of object and is the direct factor which decides the running sequence for objects
连线技术的研究内容属于平台的系统框架及运行机制研究的范畴，连线在软件平台中具有相当重要的地位，它是编程两大元素(控件，连线)之一，它表示的是控件间的数据依赖关系和控制关系，是数据流和控制流的显式表现，是程序中决定控件运行顺序的直接因素。 - Furthermore , when the divided ii1 differences are used to approximate to the derivatives that are coefficients in linear arithmetic representations , computing linear arithmetic representations is converted to compute predicate residuals completely , which needs to analyze neither static nor dynamic data dependencies between the statements on w . at this time , the improved method is more powerful to generate test data , and can be used for black - box testing
更进一步，当用均差作为谓词函数关于输入变量的导数的近似时，计算线性算术表示就全部转化为计算谓词残量，而后者无须分析w上各语句之间的静态、动态数据依赖关系。此时，改进后的方法比原方法生成测试数据的能力更强，能够用于黑盒测试数据的自动生成。 - This thesis gives a model language and a moderately complete formal description which can be used to prove the properties of static and dynamic data dependencies , and defines the notions in the iterative relaxation method formally . the program theories about the iterative relaxation method and its improvement are investigated , whose results include : the generalization of the predicate slices proposed by neelam gupta et al to path - wise static slices , and the proofs of the soundness of the construction algorithm of path - wise static slices and the soundness of the improvement
本文给出一种模型语言；给出一个比较完整的形式化描述，该描述可用于证明与静态、动态数据依赖关系有关的程序性质；给出迭代松弛法中各概念的形式化定义；深入研究迭代松弛法及其改进后的方法的程序理论，其结果包括：将neelamgupta等人提出的谓词片推广为路径静态切片，证明路径静态切片构造算法的正确性，证明改进后的方法与原方法所生成的线性约束系统相同。 - The following works have been done : ( 1 ) define csl language and complete the lexical analysis and syntactical analysis of it ; ( 2 ) obtain control flow graph ( later referred as cfg ) from abstract syntax tree ( ast ) ; ( 3 ) control dependence analysis of csl ; ( 4 ) system architecture of csl slicing system
内容包括通过语法分析获得源程序的抽象语法树,从抽象语法树构造控制流图,在控制流图上做控制流分析获得源程序的控制依赖关系,在控制流图上做数据流分析获得源程序的数据依赖关系,以及最后获得源程序的程序依赖图并以图可达性算法获得程序分片的全过程。
