A method and system for displaying names of data files in a collection of data files represented by a corresponding symbol. According to one embodiment of the present invention, a user may display a listing of subroutine library files required to execute a particular subroutine. In such an embodiment, the user may enter the subroutine name as the symbol of interest and the system would display the library file containing that subroutine as well as those data files that contain subroutines called by that subroutine of interest. The present invention uses a transitive closure technique to traverse a data structure generated from a database and retrieve the data file list. The transitive closure technique enables the use of a compact database that contains only the data file names, corresponding symbol names, and symbol names of only data files for each data file that are directly related to that data file.
