Business Interoperability

Service Oriented Architecture (SOA) is gaining acceptance, offering advantages including closer alignment of IT systems with business. Ideally, within large enterprises, capabilities would be used by solutions from a number of business units while matching the detailed requirements of each; this level of interoperability is difficult to achieve. While much of the current activity focuses on technical interoperability we propose that the focus shift to business interoperability as the key consideration to bring clarity to the engineering aspects of technical interoperability. A model-driven architectural approach is presented that views an organisation’s business processes as structured assets requiring formalisation. A new concept is presented, the conceptual business service (CBS), which provides abstraction through modeling, and promotes building a portfolio of navigable business services at the appropriate level of abstraction and granularity. A method for specifying a CBS is outlined using reference domain meta-data allowing easier service solution recognition among other benefits.

The Cost

Since the early 1980s, Open Source Software (OSS) has gained a strong interest and an increased acceptance in the software industry that has to date initiated a “paradigm shift” (O’Reilly, 2004). The Open Source paradigm has introduced wholly new means of software development and distribution, creating a significant impact on the evolution of numerous business processes. In this chapter we examine the impact of the open source paradigm in the e-Procurement evolution and identify a trend towards Open Source e-Procurement Application Frameworks (AFs) which enable the development of tailored e-Procurement Solutions. Anchored in this notion, we present an Open-Source e-Procurement AF with a two-phase generation procedure. The innovative aspect of the proposed model relates to the combination of the Model Driven Engineering (MDE) approach with the Service-Oriented Architecture (SOA) paradigm for enabling the cost-effective production of e-Procurement Solutions by facilitating integration, interoperability, easy maintenance, and management of possible changes in the European e-Procurement environment. The assessment process of the proposed AF and its resulting e-Procurement Solutions occurs in the context of G2B in the Western-Balkan European region. Our evaluation yields positive results and further enhancing opportunities for the proposed Open Source e-Procurement AF and its resulting e-Procurement Solutions.

Root Of Trust

Service Oriented Architecture (SOA) is an architectural paradigm that enables dynamic composition of heterogeneous, independent, multi-vendor business services. A prerequisite for such inter-organizational workflows is the establishment of trustworthiness, which is mostly achieved through non-technical measures, such as legislation, and/or social consent that businesses or organizations pledge themselves to adhere. A business process can only be trustworthy if the behavior of all services in it is trustworthy. Trusted Computing Group (TCG) has defined an open set of specifications for the establishment of trustworthiness through a hardware root-of-trust. This paper has three objectives: firstly, the behavior of individual services in a business process is formally specified. Secondly, to overcome the inherent weaknesses of trust management through software alone, a hardware root of-trust devised by the TCG, is used for the measurement of the behavior of individual services in a business process. Finally, a verification mechanism is detailed through which the trustworthiness of a business process can be verified.

Model Driven Approach

The authors of this chapter argue that business processes can be modeled in the same way as collaborative business services, and therefore use an approach developed for such services. They consider business services that are collaborative and crosscutting in nature; several participants may collaborate in a business service to achieve its goal, and a participant may take part in several different business services, playing different roles in each. A framework to support the development and composition of such business services is the main focus of this chapter. The authors use UML collaborations for modeling the structure of roles involved in a business service/process, and activity diagrams for specifying the global behavior performed by the roles. From these models, reusable components realizing the roles can be automatically synthesized, and such components can then be composed together in order to make different systems that meet the requirements of business services.

Architecture Modeling

This chapter focuses on the identification and specification of services based on prior modeled business processes and legacy systems. The resulting service interfaces and service components formalized by using the Service oriented architecture Modeling Language (SoaML) describe the integration of legacy systems into a service-oriented application landscape. The legacy systems provide services for integration purposes and represent the implementations of service components. Additionally, the resulting architecture allows functionality of legacy systems to be replaced with functionality provided by external cloud services. According to model-driven development concepts, the formalized service interfaces and service components as part of the service designs can be used to automatically derive service interface descriptions using the Web Services Description Language (WSDL). These descriptions enable the technical integration of legacy systems. If necessary, service implementations based on the Service Component Architecture (SCA) and the Business Process Execution Language (BPEL) can be generated.

Legacy Applications

In the commercial world, the value of ubiquitous computing applications is proportional to the range of business services that can be accessed in device-consumptive ways. Services originate in legacy applications of organizations, and are developed and operated typically in heterogeneous environments. Service-oriented architecture (SOA), supported by a complex stack of Web services standards, addresses ways in which software components of diverse applications can be homogeneously interacted with and composed. Thus, SOA provides a crucial mechanism for making services accessible to ubiquitous computing applications. In this chapter, we shed light on what SOA entails, based on Web services interfaces and messaging, and service composition through single-party process orchestration and multiparty choreography languages. For the latter, concrete patterns are used to describe the capabilities of prospective standards. Ways in which SOA needs be extended to allow wider and more flexible service trading, typified in current developments through service marketplaces, are then discussed. Such extensions, we argue, converge with directions in ubiquitous computing through so-called ubiquitous service networks and service ecosystems.

Since the beginning of the Service-Oriented Architecture (SOA) paradigm, with its various implementation technologies such as Web services, the focus of industrial communities has been on providing tools that would allow seamless and flexible application integration within and across enterprises’ boundaries. In this paper, the authors present a Context-based, Service-oriented Modeling and Analysis (CSMA) method that guides service engineers in their choices of identifying, defining, and analyzing adaptable business services. The proposed method is business centric and comprises a set of structured steps grouped in two phases. Besides, the CSMA embraces Model-Driven Architecture (MDA) principles to model and refine adaptable business services models in the PIM level. The results from a pilot validation of CSMA for SOA enablement of a realistic enterprise training solutions are also presented.

In Service Oriented Architecture (SOA), each application is designed with a set of reusable services and a business process. To retain the reusability of services, non-functional properties of applications must be separated from their functional properties. This paper investigates a model-driven development framework that separates non-functional properties from functional properties and manages them. This framework proposes two components: (1) a programming language, called BALLAD, for a new per-process strategy to specify non-functional properties for business processes, and (2) a graphical modeling method, called FM-SNFPs, to define a series of constraints among non-functional properties. BALLAD leverages aspects in aspect oriented programming/modeling. Each aspect is used to specify a set of non-functional properties that crosscut multiple services in a business process. FM-SNFPs leverage the notion of feature modeling to define constraints among non-functional properties like dependency and mutual exclusion constraints. BALLAD and FM-SNFPs free application developers from manually specifying, maintaining and validating non-functional properties and constraints for services one by one, reducing the burdens/costs in development and maintenance of service-oriented applications. This paper describes the design details of BALLAD and FM-SNFPs, and demonstrates how they are used in developing service-oriented applications. BALLAD significantly reduces the costs to implement and maintain non-functional properties in service-oriented applications.
