| With the rapid development of B2B e-commerce, it is a general trend to building a B2B e-commerce platform to ensure all companies can do their B2B trade in a neutral the third party platform. But currently the construction of B2B e-commerce platform has retained many problems, firstly, functionly restriction of single Web service could not meet users' need; secondly, the inelegant combination method of services made a huge waste of resources; thirdly, communication between heterogeneous datas and heterogeneous systems still had problem; fourth, ignoring of the match to the real business environment impacted the business process; finally, ignoring users's requirement of quality of service.This paper based on analysis of mainstream technology and platform construction model at home and abroad, analyzed of the existing shortage in traditional platform construction, combined with Web Services technology, SCA/SDO model, BPEL technology, presents a B2B e-commerce platform architecture based on SOA, gave out the specific design of the layers model. With the background of a project the author had evolved, constructed a B2B E-commerce platform called MyB2B. Based on the requirement and business functions and processes analysis, gave out the platform's overall design, interface design, the main function's SCA model design, SDO definition, and the corresponding business processes implement, and gave out the security design and the system test. At the last, this paper introduced the importance of constructing a evaluate model of services in the platform, and proposed the evaluate indexes system of services and the services evaluating model.The architecture proposed in this paper has solved the existing shortcomings in e-commerce platform constructing in service modeling, services communication, business process constructing and service quality evaluation, proposed a feasibility design for B2B e-commerce platform construction, and proposed the prospects of B2B e-commerce platform development. |
