Lawrence Livermore Laboratory (LLL) investigated a new approach for improving the use of geographically distributed computer services used by the U. S. Department of Transportation/Transportation Systems Center (DOT/TSC). The interactive use of these distributed services (a major portion of which are data bases) consumes increasing amounts of the DOT user-analyst's time. The new approach increases accountability, selection capability, usability, and control of distributed services usage. LLL's approach centers these four elements in MODDS, which is an intermediary between the user-analyst and the distributed computer services. This report summarizes the current problems faced by the DOT community, then presents a digest of MODDS advantages. 2 figures. |
