This time, it will introduce by Web service it is actualized new Internet computing - - concerning the global class computing of the place where says. As for global class computing, when you express in one word, the fact that "dynamic cooperation of group of enterprises becomes possible in on Internet" is feature.

It will try thinking of the case where the airplane, the rental car and the hotel are reserved for the American business trip as the example which is easy to understand. Even presently,bythe fact that the online travelling portal of and the like is utilized, it compares the fee of each company, optimum air mail, the rental car, selects the hotel, can reserve from Web. Usually, as as for the existing travel agency and the like become unnecessary without many problems with this, you can think. But, schedule of business trip was modified, when we assume that stroke slipped in 1 weekly rear, how probably will be? If it is the existing travel agency, "with the same distance shifting everything in 1 weekly rear," you probably will be allowed to ask distantly. But in case of the travelling portal, respectively, one by one it must cancel the airplane, the rental car and the hotel and it must process re-reservation.

In addition, because you desire air mail full it is the seat, we will assume that from another airport it does not face to destination it became necessary by the rental car. In order to find optimum distance, you must check the enormous combination it detours from some airport, uses which rental car company of by your without the . The travelling portal of present time is visible, like whether being able to integrate travelling-related business service it is of, but, it is not the case that just you unify the window really, do the organic cooperation between the airliner, the hotel company and the rental car company. Cooperation between enterprise it is entrusted to the manual operation of the user. This, is one of the limit of conventional type Internet computing.

In the world of global class computing, as for the travelling portal utilizing Web service effectively, the airliner, the hotel company and the rental car company etc. and it cooperates to real time, from midst of enormous combination it probably reaches the point where the optimum distance which coincides to the condition the user desiring is found automatically. When schedule becomes modification, new schedule just is input, to do cancellation and the re-reservation which automatically are necessary, it probably reaches the point where stroke is renewed.

In a manner of speaking, from reform "the do it for me" model actualizes "the do it youself" model to.

This way group of enterprises cooperating, there are also times when system in order to offer best service to the user is called B2B2C. B2B2C is one of the important aspects of the global class computing which becomes possible depending upon Web service.

Global class computing also the transaction between enterprise of B2B reforms. As for enterprise finding the partner enterprise which can offer best condition at that point in time transaction of specification without being limited first, in real time, it reaches the point where it can transact. Perhaps the point that, the customer is decided dynamically, it makes the e- market place remember. But, as for the e- market place of conventional type, as for Web service everyone of the entire world the point participation possible differs closed it can participate just the specific enterprise which is registered beforehand vis-a-vis being the place.

Because here, it can transact on a lot of Internet, saying, perhaps unfamiliar enterprise and that it does transaction, it is thought as the lith key even excessively. Besides the fact that in order to solve this kind of problem, it was based on financial affairs circumstance and the appraisal of the market the enterprise which offers the information of grade of enterprise with Web service probably will appear. Furthermore, also the Web service which offers balancing of accounts function and escrow function probably will appear. These Web services offer added value by the fact that it lies between in transaction between enterprise, in a manner of speaking it is trading company existence. Depending upon the medium pulling out effect of Internet, there are times when an argument that is heard the trading company and the like becomes unnecessary, but, if to tell the truth Internet business evolves, necessity of the extent trading company service which is done it increases.

Of course, ideal of this kind of global class computing, is not the case that overnight it is actualized. Security and rating etc. are future important topic. Especially, you expressed big topic, even in the past, but, it is standardization of content of the data which is exchanged by Web service. As for this kind of standardization job, rather than calling technical topic, the plural enterprise presents and others are the political topic which is due to seeing, are the process where time is required generally. In addition, because Web service spread, saying, transaction between all enterprises will be done probably there are no times when it becomes with Web service. With transaction of performance concern of the enterprise which has the close relationship of the subsidiary company and the like EDI of conventional type probably will continue to be used and, closed also the e- market place probably will keep being used. As for the point, there is about system of transaction between optimum enterprise can be selected in compliance with important matter such as performance and pliability.
