Flow chart of the database operation – registration of actions. If the user processes the loaded data using any preprocessing method in jMRUI, the macro key (short name of each routine), which corresponds to the preprocessing method, is stored in the action column of the ACTIONS table. A new action identification number is generated and saved in the column ID_action in the ACTIONS table and in all other related tables as shown in the figure. Processing parameters (and if a parameter is a file also the file hash sum) are stored in the PARAMETERS table. The parameter files, if any, are stored in the preprocessing files directory. A new entry is created in the FILES_ACTIONS table linking the processed file (its ID_file number obtained from the “OPEN FILES” registry) with the action performed (identified by the action ID_action number). If the user decides to quantify the currently loaded data, jMRUI will store also the quantitation result file. The result file is stored in the results file directory and the hash sum of the result file is stored in the table RESULTS
