A.2.7
IOL stub
when CORBA Is used and the client and server communicate, the dent program that accesses the operation on the server side provided wIth the corresponding peeudo-obØct (as a part of API) on the client side
A.2.8
naming service
common reference service provided by CORBA
NOTE The naming srvice responds to the Inquiry from the obed, retating the name of the object to Its location in the natwo&
A.2.9
naming service Interlace
program, which executes the API request from the user application, in the senes of processes when a nammg service n used
&2.1O
0MG
Object Management Group
international standardization group which presaibes tedinology for the infrastructure which is necessary for the development of the application in the environment of the dispersion of object oriented architecture arid independent of the hardware
A.2.11
ORB
Object Request Broker
software which provides the tasks of communication between stub and skeleton
&2.12
read data
operation of reading one partictiar datum from the database, on the specthed server
A.2.13
user application
program, whlde is established by the user of the FMSN in accordance with the requirement by the LlTP-nstalled system to realize the functionality on the FMSN
NOTE The functionality on the FMSN senes to acquire the operational management irifomeation and/or the steip management infurmalion.
A.2.14
user-application Interface
interface n the API opened between the API and user application
NOTE Thai o delnee four kinds of operation (Reed data, WMe data, Acquire data list and Acqure ship Information) as desol*d In the AA. 12 to A.4,3.2.
&2.15
writ, data
operation of writing one particular datum to tie database, on the specifIed server
A.3 Objectives
See 7.2 0verview of APIs in the main text.
For design of the software of the API, the blowing objectives should be considered:
a) malce the system platform transparent to the programming language and development environment of the application;
— Write data
Invokes a program for accesses for the wits data operation In the IDI. stub block.
— Acquire data 1st
Invokes a program fur accesses fur lie acquire dt list operation ii the IDL stub hock.
— Acquire slip information
Invokes a program for accesses for * acquire ship liformation operation in the IDI stub block.
— Naming service interface
Invokes a Narnmg service operation, provided by ORB, and acquWes the Object reference for the server.
— IDI skeleton
Requirements of each operation, which are issued from 1h cMent program of the LITP.wistalled system.
are transmitted to the API server program.
&4.2.4 IDL stub block
— Readdata
It requests the invocation of an operation program for the read data on the database server to the ORB.
— Wflledala
It requests the invocation of an operation program for the wñte data on the database server to the ORB.
— Acquire data 1st
It requests the invocation of an operation program for the acquie data 1st on the database server to the
ORB.
— Acquire slip 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 sorvar
A4.5.1 Illustration
The database server software configuration Is schematically shown In Figure A.3, surrounded by a dotted line.
