Guidelines for implementation of a fleet management system network.
2.6
client/server architecture
architecture of computers called servers that manage shared resources and provide access to those shared resources as a service to their clients
2.7
computer system
functional unit, consisting of one or more computers and associated software, that uses common storage for all or part of a program and also for all or part of the data necessary for the execution of the program
2.8
fault tolerance
built-in capacity of a system to provide continued correct execution in the presence of a limited number of hardware or software faults
2.9
independent
independent, as applied to two systems, means that either system will operate with the failure of any part of the other system
2.10
interface
interface attribute describes the methods and rules governing interaction between different entities
2.11
land-based communications hub
land-based computer system that provides uniform access to multiple maritime satellite services, as well as access to public telephone networks, e-mail and the Internet
2.12
ship earth station
mobile earth station for maritime satellite service located aboard a ship
2.13
software
programs, procedures, rules and associated documentation pertaining to the operation of a computer system
2.14
validation
test and evaluation of an integrated computer system (hardware and software) to ensure compliance with the functional, performance and interface requirements
2.15
ship information technology platlorm
SITP
integrated system of software, hardware, communication links and standardized procedures that provide common services to shipboard systems in a standardized form
2.16
verification
process to determine if the product of each phase of the digital computer system development process satisfies the requirements set by the previous phase
2.17
white box test
test where the test plan is based on knowledge of the internal structure of the module being tested
See black box test (2.3)
The FMS provides mult-vendor connectivty，,distributed processing and electronic data interchange betweennetworks, computers, workstations and peripherals. lt also maintains databases and computer applications softwarethat promote safety of life at sea, protection of the environment and operational efficiencies throughout the life cycleof the vessel/fieet. The FMS may incorporate satellite gateways to coastal communications hubs providing access toland-based networks such as telephone lines, facsimile,e-mail Internet services, and expanded satellite servicesthrough land-earth stations.
— Write data
Invokes a program for accesses for the write data operation in the IDL stub block.
— Acquire data list
Invokes a program for accesses for the acquire data list operation in the IDL stub block.
— Acquire ship information
Invokes a program for accesses for the acquire ship infomiation operation in the IDL stub block.
— Naming service interface
Invokes a Naming service operation, provided by ORB, and acquires the Object reference for the server.
— IDL skeleton
Requirements of each operation, which are issued from the client program of the LITP-installed system,
are transmitted to the API server program.
A.4.2.4 IDL stub block
— Read data
It requests the invocation of an operation program for the read data on the database server to the ORB.
— Write data
It requests the invocation of an operation program for the write data on the database server to the ORB.
— Acquire data list
It requests the invocation of an operation program for the acquire data list on the database server to the ORB.
— Acquire ship information
It requests the invocation of an operation program for the acquire ship information on the database server to the ORB.
A..4.2.5 Naming service
It acquires the Object reference for the database server.
A.4.3 Database server
A 4.3.1 Illustration
The database server software configuration is schematically shown in Figure A.3, surrounded by a dotted line.
