Background technology
Under the global commerce competitive environment that is growing more intense in the modern times, MRP and information integrated whether can carrying out rapidly and efficiently between inner constituent parts of e-Business and business partners have been that can enterprise have one of important document of competitive edge.This also makes the more and more enterprises system use Enterprise Resources Planning (ERP) and supply chain management (SCM) instrument one after another, in the hope of can be fast and integrate the resource of upper, middle and lower trips business partners effectively, the information that reaches between enterprise be passed on and the rapid-action purpose in real time.Yet because the commercial intercourse flow process between enterprise system is complicated and infosystem that adopted each other is mostly different, so the integration of information flow between enterprise system and workflow is a complexity and a masty difficult problem.For example, a business transaction flow process can comprise many steps usually: inquiry, price negotiation, transaction place an order, payment and shipment, and will produce a large amount of transaction datas and file record in the process as pro forma invoice, order form, bill of sales etc.; These data documents need come and go transmission between both parties in transaction is carried out, therefore effectively and data transmission fast be a most important ring in the business transaction flow process.A desirable business automation flow process should be after the client imports related data and proposes services request, system will automatically give the data transmission that this client imported and serve relevant enterprises system therewith, also can apace the integrate information after handling be passed to outside cooperative cooperating manufacturer.
In order to overcome the communication problem of heterogeneous infosystem between enterprise, the existing multiple at present electronic information exchange specification based on XML is as ebXML and Biztalk.And Microsoft, IBM, HP, Sun Microsystem also propose network services (Web Services) such as .NET, Dynamic Web Services, E-Speak, ONE respectively and support conceptual framework.Put application system along with enterprise utilizes network service (Web Services) to build widely, (Web Service Oriented Applications WSoA) will become the development main flow of enterprise application future can to predict network service orientation application program.
Network service (Web Services) is one and has opening, distributed component software, its basis is based upon on the agreement of standards such as HTTP, XML, SOAP, WSDL, and the user can describe and write network service (WebServices) with any program language developing instrument and operating system.Network service (Web Services) provides (long-range) the object interface of calls and the application program writing specification of a standard, and the program language that the programmer can use him to be familiar with to carry out access and calling with other network service (Web Services) assembly that is positioned on the network.Because the XML file specification standard of self-description is used in network service (Web Services), and (Simple Object Access Protocol is SOAP) as the communications protocol of calling out between network service (Web Services) for the simple object Access Protocol of the standard of use.Therefore, no matter be the information communication of constituent parts in the electronic enterprise, or and outside partner between the Heterogeneous systems message exchange, network service (Web Services) framework all can provide the conforming mode of intelligence transmission and information integrated service.
Figure 1A is the Organization Chart of traditional network service orientation application program.Figure 1A shows, network service orientation application program 15 is applied to the network 11 that formed by 10 frameworks of a plurality of client computers, and network 11 is represented an Intranet (Intranet) or internet (Internet).By among the figure as can be known, network service (Web Services) framework is to be based upon already present Intranet or internet, and client computer 10 uses simple object Access Protocols (SOAP) 14 to ask (Request) or (Provide) network service module 12 is provided, and then uses simple object Access Protocol (SOAP) 14 to link up talk each other by network service module 12 and finish the work with cooperation.Yet traditional network service orientation application architecture but has running shortcoming such as complicated, consuming time.
See also Figure 1B, it is the framework schematic diagram of Figure 1A.Show and easily know, Figure 1B is a complete figure (Complete Graph), that is to say, in network service orientation application program 15, when 12 of all-network service modules need to share some state (States) data or object each other, 12 need of wantonly two network service module each other by external call transmitting shared data, so the basic structure of Figure 1A is a complete figure.When network service module 12 and 12 of network service module must be with outside method of callings in cooperation, transmit and share the opposing party that data is given cooperation, to keep the consistance of data, this will make the communication time complexity (time complexity) of Figure 1A when running up to O (N
2), wherein variable N represents the number of network service module 12.So traditional network service orientation application architecture has shortcomings such as running is complicated, consuming time, cost height.Face continuous requirement in real time, under the global commerce competitive environment of efficient, traditional network service orientation application architecture day by day can't satisfy the demand of the e-Business of surge.
In addition, along with the object of network service module 12 is the more shared, cause the message content of simple object Access Protocol (SOAP) will comprise the more parameter, and the message with simple object Access Protocol (SOAP) of huge content is difficult for processed, therefore for the enterprise software development in future, also can cause complexity to a certain degree.
