Data
Integrity -- Was the correct version of each file used in the
process, or did some out-of-date or stray data creep in to the
process?
SAGE manages the location and status of the tools,
files, and scripts in the flow. It understands the files' logical
dependencies - it knows whether they're up-to-date or not.
Flow
Standardization -- What are the specific commands and command-line
arguments? What environment variables are necessary for a tool?
SAGE provides a living, working vision of the flow,
including command-line arguments and UNIX environments. The SAGE
model of a flow is a working standard that can be understood and
re-used.
Flow
Integrity -- Were all the steps performed correctly so far? Were
the right tools used at the right time? And what step is next?
SAGE maintains a database identifying the exact
tools used, when they were used, and what the results were. Transparent
to the user, SAGE tracks what tasks have been performed, as well
as those that are to be performed next.
Project
Tracking -- Where am I right now? Which jobs ran? Which ones failed
or passed? Where are the reports associated with that step in
the flow?
SAGE controls the operation of the flow by launching
jobs, sequentially or in parallel, waiting for previous steps
to complete or for the required prerequisites to be met. SAGE
can run jobs locally, or distribute them using a job queuing system.
