A modeling approach for service-oriented architecture

Abstract

Specifying service-oriented system, which is a new type of Enterprise Information System, is critical with the rapid development of Web Services. For the purpose, this paper presents an approach to model Service-Oriented Architecture (SOA). We do not exclude the traditional opinions of software architecture description as the current specification approaches; on the contrary, some similar conceptions, such as service components and connectors are defined in this paper. For architectural reuse, the notion of composite service components is specified to model services composition and that of composite connectors is defined to abstract the complex communication protocols. Within the context of the Travel Reservation System (TRS), we demonstrate the usage and practicability of our approach based-on Web Services.
