The Rubiscape process for analyzing data is - read the data, process it based on the algorithms selected, and display the result. In this process, Rubiscape stores your data only in the temporary cache. After the result is displayed, the resultant data is cleared, and you cannot access it later.
However, Rubiscape provides an option to save the resultant data to a file or a table. This is achieved using the Writer functionality of rubiscape. The data can be written to a table or a file and can be reused later. This table or file created is the target table dataset or the target file dataset.
