BACKGROUND matter by step-by-step method. The reason for

this is that an active new change in system is
not considered in this situation. That is to say, a
new factor in the system does not come up for
an available use. If it does, another new system
should be made for this purpose. And so we can
say that these processes are rigid and static, so
that only the matters related with the processes are
retrieving data and reuse them for getting output.
Here we will see the service systems more in
detail that have been explained in the above by
giving some examples. And also some subjects
that are existed in the systems will be mentioned
briefly too.

Generally speaking, we have now a system for
service in order to get a request done almost in
all categories in various aspects like book, food,
entertainment, sport, house, opportunity hunting,
travel, music, culture, study, education, training,
management, control, production, marketing,
transformation, etc. by means of IT facilities, a
networking, and a communication. As we know
well, we are able to appreciate those services
especially through the Internetworking and other
IT facilities. In the case of “book” matter, book
purchase, reading, searching, writing, publishing,
and topic data storage can be done through the
Internetworking quite easily, for example. And
the same kind of services can be seen almost all
in other fields. And this direction for service will
be going further on in the future.
The mechanisms that are used for these ser-
vices are mainly realized by computer and the
Internetworking with data storage, data retrieval,
and processing techniques. So the numbers of
the key technological mechanisms that are used
are not many, which mean that the complexity of
these services is not deep and wide in terms of the
technologies and the methods. Of course, if we
think about a security of these services, the issues
are a bit different and complicated.
If these services are described by an abstract
expression, these matters will be provided by sim-
ply “Demand or Search” through “the Processes”
as shown in Table 1 (Sugiyama 2008).
Systematically speaking, this kind of system
can be made by using a tree structure of system
that will be able to offer a demanded (requiring)

1. Business Plan Service System: This Service
offers a business plan for users as it is desired
in a required field, and this Service may give
a necessary advice at each process if it is
necessary. But the contents of business plans
cannot be changed instantly and easily.
2. Market Research Service System with
GPS: This Service offers a market research
in a target category and for a targeted purpose
by using GPS, for example. But the basic
analysis and synthesis methods cannot be
changed easily.
3. Engineering Training/Education Service
System: This Service offers training and edu-
cation in terms of business category as they
are required by using the Internetworking
or database. But those method and contents
cannot be improved quickly at the moment
when they are required (Larson 2009).
4. Sales Service System: This Service offers
DM by DTP and Email Service as it is wanted

Table 1.

Demand and Search → Processing; Database, Matter, etc. → Output; Thing, Information, Data, etc.

(Requiring) (Search, Retrieve, Production, etc.) (Thing, Goods, Plan, Management, Data,

Information, Knowledge, etc.)
