System Management System Subsystem
The System Management System (SMS) sub-
system of SNAP II performs system management
and system service tasks in support of the other
functional subsystems of SNAP II. SMS ship-
board functions are of three types:
1. Functions accessed by the user from the
SMS menu
2. Functions accessed by one subsystem from
another subsystem
3. The SNAP II system menu function that
provides a common entry point to SNAP II for
all users
The SMS is responsible for protecting system
data integrity by providing backup, recovery, and
transaction logging functions. Output queue
management is supported as well as the system
on-line users manual. Figure 10-4 shows the main
menu encountered upon entering the SNAP II
system.
Maintenance Data System Subsystem
The Maintenance Data System (MDS) subsys-
tem provides support for on-line interactive 3-M
Systems for SNAP II ships. The MDS and the
Supply and Financial Management (SFM) sub-
systems are the only two that are specifically
related to each other, in that, as a maintenance
person you can order supply parts through the
MDS.
This subsystem includes 3-M functions related
to the Current Ship’s Maintenance Project
(CSMP) master data base. This data base consists
of Maintenance Data Collection System (MDCS)
actions, Configuration Change (CK) actions, and
Ship’s Force Work List (SFWL) actions. The
MDS provides the following capabilities:
1. Management of CSMP actions, including
adding, closing, changing and displaying, and
maintenance actions
2. Trouble log processing
3. Equipment calibration and testing (MEA-
SURE) and ship’s tickler file processing
4. The ordering of both maintenance-related
and nonmaintenance-related parts from supply
