with a quick service by using the Data. But
the method cannot be changed quickly and
instantly.
5. Necessary Information Retrieval Service
System: This Service offers necessary infor-
mation by customer's involvement of making
the database, for example. But if some kind
of new processes are required, the system
structure must be improved as well, which
is not easy matter to do.
6. Strategy Planning Service System : This
Service offers a support for making a busi-
ness strategy plan by using database. But if
the strategy is needed to change, it might
be suggested to make a new system accord-
ing to a new strategy. Because it should be
studied from the first stage about the strategy
and then it needs to reconstruct the whole
system again. And so it needs lots of time
and money again.
7. Publishing and Information Service
System: This Service offers any service in
Publishing and Information by IT. But if
other functions are required to add into the
system, it cannot be done easily and instantly.
8. Production Service by CAD/CAM system:
This Service offers a total production sup-
port from design to production. But it is very
difficult to change the system even though
it is quickly required because the system
should be made from the first stage in the
system flow with new processing methods
and data (Sugiyama et al. 2007).
9. E-Learning Service System: This Service
offers a learning opportunity for any one at
any place and any time (Larson 2009). But
it needs time to change the system when it
is required.
10. Home Security Service System: This
Service offers a present situation of Home by
sight, which mean whether or not “TV is on
?”, “Air condition is off ?”, “Nobody there
?”, or “is there anybody ?”, etc. But if the

system is required to add another function,
it must need time and more money. etc.

As shown in the above, we have lots of service
systems by using this basic “Demand and Search”
method. The above Service Systems will be also
described schematically as shown in Figure 1.
At this point, we have to make clear that these
Service Systems will offer necessary processes
and outputs with step-by-step manipulations when
they are required under the conditions that “Com-
puter Systems with IT and Communication Tech-
nologies” are available in an ideal manner.

MAIN FOCUS OF THE CHAPTER

Principle for Engineering Service
Based System by Swirl Computing

We firstly think about the development of Informa-
tion and Communication Technology (ICT). After
the internetworking and the related technologies
have been come up to our daily life originally from
the initiators' institutes in US, and then from major
universities in US, and then from major universi-
ties in the world, and then from the major institutes
of related companies in the world, we are able to
enjoy communicating with anyone and anything
at any time in the world once when we have the
necessary systems and the facilities. And after
having passed these times, they have been able
to be applied to various categories of fields, like
