A Component Model Based on Semantic for E-Commerce PaaS Platform

As one of the most important patterns of cloud service, PaaS provides an entire development, deployment and runtime platform for SaaS applications. In a specific PaaS environment such as e-commerce platform, there are similar functionalities among multiple applications, such as "searching items". In this paper, we focus on enhancing general PaaS platform with the mechanism of shared component-based application construction. We discuss some key issues of constructing such abilities with large number of heterogeneous components in the PaaS platform. A component layer with a semantic-enabled multi-level abstract component model is constructed and added to the general PaaS platform. We also give a description of the prototype of our enhanced e-commerce PaaS platform, which can efficiently simplify SaaS application constructing with reusable components.
