The Multi-Tenant Data Architecture Design for the Collaboration Service System of Textile & Apparel Supply Chain

Multi-tenant technology is one of key competencies for software as a service (SaaS) to achieve higher profit margin by leveraging the economic scale. In China, there are a number of textile & apparel OEM enterprises, but due to the lower value-added products, they can not invest on information platform with very big budget. A collaboration service system supporting multiple tenants can significantly reduce cost of customization, deployment and operation of a great number of textile & apparel enterprises. This paper designs and implements a collaboration service system for textile & apparel supply chain. In this system, all tenants share the same infrastructure and application instance. However, from the user experience, the tenant would naturally dedicate to access and use the service as if there were dedicated ones. Therefore a cost-effective and secure multi-tenant infrastructure, especially in data access architecture, should be carefully considered. We analyze the key implementation patterns of data access multi-tenancy on aspects of isolation, security and customization. Furthermore the detailed access control flow is demonstrated.
