Abstract:

In order to obtain the structured data that the third stage solar wind particles can analyze and process, we load the data into memory and use the technology of LINQ to solve the integrity of data mapping and quick access. By designing a data mapping model, the labels and products of the PDS data will be mapped to the codomain and the attribute domain separately. The experimentation is made, and double caching and the Bessel interpolation are adopted. The empirical results show that the model features effectiveness, completeness and high alignment. This model which is based on memory mapping can be a better way to solve the heterogeneous data source power shortage problem during the rapid access of the structured data. It gives a foundation to analyse the frequency spectrum, the ingredients the flux and the distribution characteristics varying with time and space.
