摘要:
In order to compare and analyze data from various sources and to enhance data processing efficiency, this paper provides an approach to manage and compare data with multi storage types. To start, the data storages types are categorized into 2 types, which are simple listed text file and complex formation file. Through three retrieving route-database, text file and configuration file-data can be listed into a comparing form. By selecting, order adjusting and figure setting, the data in the listed form can be rearranged. The comparison setting information can be saved as configuration file for fast reloading and browsing. After being preprocessed, the data can be shown into curves for visualized comparison, and the result can be output as file or bitmap. This method has been applied for a certain rocket's data analysis and has met the demand of multi-typed information management. © 2019 IEEE.
