Research On Business Modeling Methodfor E-commerce

In recent years,E-commerce has been growing rapidly.Innovative business modes(B2B2C,C2 B,C2M).have been developed,novel commercial content(brand management,content-based,community,personalization,local life)has been enriched.With the various peripheral systems,ecological scale and complexity of E-commerce are increasing,which leads to the rapid change of business demands,the emergence of new services,and high business complexity.In this situation,the business modeling method has been applied in the design and development of software and platforms.Business modeling is the tool for users and technical developers to interact with requirements,which also provides a solid basis for further requirement analysis.The model is an important entry point for requirements interpretation.It reduces communication barriers for non-professional users to understand the project demand feedback.Combined with the domain knowledge,a business information system is established,so the information can be managed and the business can be visualized.This method unifies business objectives,sets business rules and resources,and enhances business process awareness,so as to better guide the software development process.Based on the research of domain modeling and business process modeling,a set of business modeling methods which combine the characteristics of business and entities are proposed in this paper.They can improve the quality of business modeling,accelerate the modeling speed and promote the development of E-commerce business.it is necessary to amend and enrich with the help of project practice.Besides,the self-learning business modeling methods can improve themselves during practice.The main contributions of this paper are as follows:(1)This paper proposes a set of business modeling methods in the field of E-commerce,which consists of two parts: the meta-model and the base-model.The meta-model is based on the three elements of E-commerce(merchandise,goods and scene).After synthesizing domain-driven design and business process modeling theory,the similarity and difference of existing business data are extracted.Then,the entity feature model is established to provide the conceptual standard for both the business experts and developers,so that they can have a smooth communication without misunderstandings.In order to improve the efficiency of business development,the entity feature model is designed to be hierarchical.The feature model can be subdivided to various layers according to the specific business information,and the subdivision level is constrained by the business rules.Specifically,the building of the meta-model is the integration process of rules.The base-model is the concrete implementation of the meta-model in the process design layer.The states,operation and transition are extended to the existing Artifact model to enhance the robustness.During the evolution of business lifecycle,all possible states of the Artifact constitute the refined process model.The lifecycle model has a refined hierarchical structure,which supports business experts to complete the process design from different levels and forms a business process model with "domain-business-process" as the mainline.The meta-model serves the business experts and the base-model serves the technical developers.It builds the business modeling from the aspects of business concept and process design,which fills the blank of the business modeling in the field of E-commerce.(2)Combined with the electronic certificate business,the effectiveness of the proposed domain business modeling method is verified.Based on the "category tree","activity tree" and "scene tree",the entity feature model of "electronic voucher" is established,and it is further improved by cutting the "entity feature model of business,commodity and order".Using both the GSM business process model and PAC rule expression,the business process refinement model and rule constraints of electronic voucher are accurately conveyed,and the business model construction is also demonstrated with concrete examples.It is proved that the proposed modeling method can be applied to the existing E-commerce business models.(3)The paper designs and implements the business modeling platform E-biz Platform.It consists of three modules,including entity feature tree management module,rule base management module and business modeling module which can be further divided to the entity feature tree clipping module,the E-commerce business meta-model building module and E-commerce business base model building module.E-biz Platform provides visual interface which displays the running process of each module in real time and gives corresponding information prompts.Moreover,users can interact with each other through the platform according to their needs.
