SnapProc works as a stand-alone on a PC without the presence of Oracle. LST files spooled in Oracle containing table structures in ASCII format are understood by SnapProc for the purpose of getting column information. Above fig. illustrates how such an import is done from a text file. Table definitions can also be manually typed in or imported from other SnapProc processes.

All processes include information from at least one table - the Master Table. The following figure illustrates how this is defined.
