Abstract


The data generated by the scientific activities of the AMS is PetaByte magnitude of explosive growth , how to efficiently manage these highly fragmented mass of scientific data has become a huge challenge in the AMS scientific activities . To address this challenge , the AMS data analysis and data processing center uses grid as the data and storage resource integration platform AMS scientific activities . Based on the data grid the AMS massive scientific data management is the focus of this thesis . In this paper, two data management model - based on the data management model of virtual data sets and data management model based on the principles of market economy . And two models based on generic data management structure of an E-Science scientific activities , focusing on the three key technologies in data management architecture : metadata management , copy management technology and data movement technology. Finally, through the integration of these key technologies , the establishment of a data grid - based Monte Carol simulation data management prototype system . The system integrates distributed heterogeneous network storage resources to form a virtual storage environment , to provide a unified web access interface for upper layer applications , to achieve a high degree of data sharing . The same time , the data management system can also be extended to other data - intensive applications , such as astronomy, bioinformatics , and so on , provide strong support for these massive data management .
