SOA软件开发中的若干开放问题探讨

Recently, Service-Oriented Architecture (SOA) is becoming a new software development paradigm in the context of Internet. Web services are a kind of implementation of SOA based on Web, and they are composed to form SOA-based software by means of compositions. Compared with the traditional software development paradigms, SOA-based software development demonstrates some unique features, such as＂loosely-coupled＂, ＂seperation of specification and implementation＂, and ＂service being able to publish, register, and use as an indepentent resource＂. In this paper, we present the basic principle of SOA-based software development, and examine open issues from the perspective of software engineering methodology. The feasible solutions to these issue is helpful to the widespread adoption of SOA in practice. As preliminary attempts, we briefly introduce some research efforts, in particular those related to adaptability and reliablitiy of service compositions.
