基于水利普查数据的函数依赖关系算法
Function Dependence Algorithm Based on Water Census Data
摘要
Abstract
Conditional Functional Dependencies (CFDs) can be made extensive use of data inconsistency and data cleaning .In order to check the consistency of water conservancy survey data , this paper , according to the characteristics of the data , divided the data into two parts , including measurement and dimensions , and clustered the measurement data , imported the concept of Conditional Functional Dependencies ( CFDs ) , redefined the Conditional Functional Dependencies , improved CTANE algorithm which finds the functional dependencies;taking reservoir engineering data for example , this paper verified that the improved algo-rithm could accurately find the Conditional Functional Dependencies of water conservancy survey data , which is good for the de-tection of data consistency .关键词
