Abstract

Integrating real-time RFID data into autonomous and heterogeneous information systems across the business value chain presents a number of challenges. At an abstract architecture level, this paper identifies important requirements for RFID data provisioning and points of integration. A non-invasive architecture style is proposed to satisfy these requirements. It has the advantages of low entry barriers, low latency, high flexibility, and independent evolvability. The architecture style is used as a basis for evaluating three existing architectures for RFID data provisioning. Various architecture mismatches that could hinder the pace of RFID adoption are identified and discussed. A new asymmetric integration approach is suggested as an alternative to existing methods.

Research Scope And Methodology

A typical RFID system is naturally a complex system that has many aspects (Sheng, Li, & Zeadally, 2008; Zhao & Gan, 2006). An RFID tag can store from a simple 96 bit EPC identifier to several Kilobytes of product and operational data. The RFID can be seen as a mass distributed database that store critical business information (Floerkemeier, Roduner, & Lampe, 2007). Data provisioning is the mechanism through which every business application can access RFID data. To define data provisioning clearly, we have to understand what RFID data is. The definition of the term turns out to be quite complex because of the diversity of RFID data and its usage. Nonetheless, we try to define it from a data flow perspective as depicted in Figure 1.
