SOADM: A Design Architectural Method for Service-as-a-Software
Service-Oriented Software Engineering is a new approach to build software solutions as services and compositions with respect to service orientation and service-oriented architecture (SOA). SOA provides the methodology to form applications (web services) as functional building blocks to build an accessible infrastructure for consumers, which is autonomous and not platform-dependent. Platform independence makes it easier to develop web services, such as operating systems, programming languages, etc. Several methods from both academia and industry have been developed for service-oriented based systems. This work first questions “to what extent a solution provided by a method would conform to service orientation, particularly, how to examine the design decisions based on quality attributes”, and “to what extent the method would align solutions with problems”. Next, it shapes methods with a framework. Then, it proposes SOADM, a method for developing Service-as-a Software (SaaS) in high ...
SOMA: A method for developing service-oriented solutions
Ibm Systems Journal, 2008
Service-oriented modeling and architecture (SOMA) has been used to conduct projects of varying scope in multiple industries worldwide for the past five years. We report on the usage and structure of the method used to effectively analyze, design, implement, and deploy service-oriented architecture (SOA) projects as part of a fractal model of software development. We also assert that the construct of a service and service modeling, although introduced by SOA, is a software engineering best practice for which an SOA method aids both SOA usage and adoption. In this paper we present the latest updates to this method and share some of the lessons learned. The SOMA method incorporates the key aspects of overall SOA solution design and delivery and is integrated with existing software development methods through a set of placeholders for key activity areas, forming what we call solution templates. We also present a fractal model of software development that can enable the SOMA method to evolve in an approach that goes beyond the iterative and incremental and instead leverages method components and patterns in a recursive, self-similar manner opportunistically at points of variability in the life cycle.

32 A Comparison of Service Oriented Architecture with other Advances in Software Architectures
Service Oriented Architecture (SOA) allows software systems to possess desirable architecture attributes such as loose coupling, platform independence, inter-operability, reusability, agility and so on. Despite its wide adoption in the form of Web services, many stakeholders both from academia and industry have limited understanding of its underlying principles. This has led to faulty implementations of SOA and in some cases, it has been implemented in places where it is not suitable. In this paper, we investigate and show the relationship between SOA and other advances in software architecture. The paper relates SOA to Architecture Patterns, Components and Connectors. We advance the view that SOA's uniqueness and strength does not lie in its computational elements but in the way it enables and handles their interaction. In this way, we facilitate the understanding of SOA in terms of other advances in software architectures that are already well understood. We believe that a good understanding of SOAs in terms of other advances in software architectures will help to reap its enormous benefits.
Service-Oriented Software Engineering
International Journal of Systems and Service-Oriented Engineering
Method engineering techniques albeit proven effective for paradigms such as function, object and component, are pertinent to limited aspects of service orientation (SO). The comparison frameworks show that the produced methods neither conform to SO design principles nor to SOA, which is an issue. This paper proposes a framework to guide engineering methods for service-oriented software engineering. It describes a method by its aggregates and the relationships between elements such as Service Science (SS), SO, SOA, SOC, and Web. The paper also describes the guidance for method engineering. The framework consists of two layered categories of entities: (C1) conceptual foundation entities: SS, SO, and SOA, and (C2) realization infrastructure entities: SOC and Web. These entities request and provide services from/to each other. The framework comprehensively describes the SOSE environment, enforces the construct service with fundamental properties and principles, produces SOSE methods tha...

Modeling and design of service-oriented architecture
2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583)
Component-Based Development (CBD) and Web Services (WS) have been proposed as ways of building high quality and flexible enterprisescale e-business solutions that fulfill business goals within a short time-tomarket. However, current achievements in these areas at the level of modeling and design are much behind the technology ones. This paper presents how component-based modeling and design principles can be used as a basis for modeling a Service-Oriented Architecture (SOA). Proposed design approach is basically model-driven, but incorporates several agile development principles and practices that provide its flexibility and agility in today's ever-changing business and IT environments.

Service oriented architecture (SOA) is an Evolutionary distributed computing from the design hypothesis based request/response for synchronous and asynchronous applications. For an application, business logic or private function became modular and presented as services for consumer/client application. These services have free connection that service interface is independent implementation. For success in business, organizations require information within the organization and Meta information. However, the existence of huge information repositories created by traditional applications prevents information flow between the external and internal parts. SOA is an approach that replaces these huge sources by loose coupling services and satisfies the required information flow and finally increases speed in these organizations.In this paper, first we study the fundamentals of SOA and then describe web services application in software engineering. In addition, we show that web services can b...
