Integration Materials Data between Heterogeneous Databases Based on Data Warehouse Technologies

In materials science, effective tools are needed to organize and systematically analyze vast amounts of highly diverse materials data stored in heterogeneous databases. We have developed and deployed a data warehouse named materials data warehouse (MDW) as a tool to apply integrative approaches to the analysis of large materials data. Integration of a data warehouse enables the proper materials data to provide the required information in a direct, rapid and meaningful way. Material researchers can view data from various perspectives with reduced query time, thus producing results faster and more comprehensive. Especially, we have organized the framework of data warehouse treated materials properties combination as different subjects. To get new materials with especially properties, researchers can pick up subjects to analysis with data mining in MDW. We expect MDW will be a useful tool for supporting materials data analysis. MDW should be one of important data sources for materials data mining.
