Abstract


With the development of data warehouse and data mining technology , communications carriers have established operating system (ie, business intelligence systems ) , a large number of day-to-day data analysis and mining to support business decisions, enhance enterprise competitiveness . GIGO (garbage in, garbage out) theory and many practical things to prove , the height of the quality of the data determines the depth of business intelligence applications . Data quality verification system came into being , and verification of the data information monitoring , alarm analysis , provides a comprehensive data quality assurance for the construction of business intelligence systems . But constantly intense , and competitive market environment increasingly complex data quality issues escalating operators who rely on daily data gradually strengthen , there is an urgent need to expand the capacity of the data quality verification system . Based on the above background , this paper presents the design and implementation of an enhanced version of a data quality verification system . The system to achieve the purpose of the comprehensive quality monitoring report file data , and enhanced interaction with the problem management system , the knowledge and information shared alarm problem , eliminate the \Of participation in the enhanced version of the system is as follows : 1. Statements of verifiable subsystem : The subsystem monitoring of data quality verification report file to get the data from the EXCEL statements and verification in accordance with the configuration verification rules , to discover the report data errors . Problem management interaction module : This module implements unified record of data quality alarm problems in the problem management system , the state of flow and other functions . Achieve unified management of data quality issues , knowledge of precipitation. Of participation subsystem modules have been in Beijing moving company on -line use , stable operation . The monthly cumulative alarm thousand times , timely and accurate error data positioning and alarm . Protect the healthy operation of the entire operation analysis system , the reliability of the data as well as the statements of the day-to-day operations .
