| Abstract: | The high power microwave system simulation platform produces large scale of complex time-varying data that bring forward new needs of data storage and process. But the existed data management methods can not provide the abilities that satisfy the platforms requirements for data storage, accessing and analysis. After deep researching on scientific data representation, metadata management, high performance I/O, parallel processing and quick searching, we have developed scientific data management software tools to integrate these technologies. As a result, data generated by the high power microwave virtual experiments could be efficiently stored, organized and managed, which have good supporting effects in promoting sub-system data exchanging, accelerating data I/O efficiency and exploring important physical problems. |
