The preliminary system design of the computer-based Southwest Regional Laboratory's (SWRL) Financial System is outlined. The system is designed to produce various management and accounting reports needed to maintain control of SWRL operational and financial activities. Included in the document are descriptions of the various types of system inputs; a definition of their data elements; the kinds of management and accounting reports generated; and an overall system flow diagram. The computer programs are to be written in COBOL for use on an IBM System 360/91. (Author/DGC)
