Engineering Test Data Warehouse-based Data Analysis To Support Environmental Research

It is one of research hotspots to support efficiently the management and analysis of engineering test data due to the complicacy and variety of engineering test activity. As a decision-support facility,Data Warehouse (DW) is widely used in information domain. Based on engineering test domain and Data Warehouse technology,this paper mainly researches the analysis facility of engineering test data.Firstly,the characteristic of engineering test data is analyzed,the management status quo and requirement of engineering test data is summarized,an engineering test data warehouse system is proposed and its architecture and characterize is introduced. Secondly,a data management system for complicated and variable engineering test data is constructed depending on description-driven technique,a framework of engineering test data analysis,which assists the implementation of professional data analysis,is suggested and the framework is interpreted in detail. Thirdly,the integration technique of distributed engineering test data and their characteristic are discussed;the integration of distributed data in a local test base or between separate test bases is implemented respectively by warehousing or mediation. Finally,An example of engineering test data warehouse system in fly test domain,FTEDWS,is depicted in appendix...
