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.

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.

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.

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.

SummaryService Oriented Architecture (SOA) has become a mainstream approach for enterprises to integrate their disparate systems — and at the same time create a closer alignment between business processes and IT. In this paper we present an overview of how to implement a Service Oriented Architecture using open standards and open source software (OSS). In particular we will look at the prevalence of open source in SOA, and explore the use of an Enterprise Service Bus (ESB) in creating and managing an SOA deployment.

Service Oriented Architecture (SOA) provides an application framework which integrates variety of technology services in a loosely coupled way. Mule Enterprise Service Bus (ESB) is a widely-used ESB product that provides important functions such as message routing, message transformation, protocol-mediation, and event handling. These functions enable Mule ESB to integrate services implemented on various platforms and technologies. However, Mule ESB does not support business logic at all. Another approach to integrate services is to use a business process language such as BPEL (Business Process Execution Language). BPEL is used to define activities along with control flow. It is limited to Web service connections. One major difference is that BPEL is capable of orchestrating a business process with programming constructs, whereas Mule ESB is capable of processing messages in many protocal connections. Both BPEL and Mule ESB have different advantages. Unfortunately, neither one is powerful enough to solve some classes of business problems. In this paper we present the COMBO framework, which merges the strengths of Mule ESB and BPEL. We develop a tool to translate an extended BPEL file to a Mule ESB configuration file. The configuration file is used within a Mule ESB to execute the process that has been described within the BPEL document. We add extension modules to the standard Mule ESB for supporting BPEL functions that Mule ESB does not provide. The extended ESB has capabilities for supporting variable assignment and conditional branches in complex business processes. Our translation can cover frequently used activities in business processes. We also present case studies that use many business activities to show how the COMBO framework supports various activity translation.

In this paper, the authors propose a Semantic Search Engine, which retrieves software components precisely and uses techniques to store these components in a database, such as ontology technology. The engine uses semantic query language to retrieve these components semantically. The authors use an exploratory study where the proposed method is mapped between object-oriented concepts and web ontology language. A qualitative survey and interview techniques were used to collect data. The findings after implementing this research are a set of guidelines, a model, and a prototype to describe the semantic search engine system. The guidelines provided help software developers and companies reduce the cost, time, and risks of software development.

Many benefits from implementation of e-business solutions are related to network effects which means that there are many interconnected parties utilizing the same or compatible technologies. The large-scale adoption of e-business practices in public sectors and in small and medium enterprises (SMEs)-prevailing economic environments will be successful if appropriate support in the form of education, adequate legislative, directions, and open source applications is provided. This case study describes the adoption of e-business in public sectors and SMEs by using an integrated open source approach called e-modules. E-module is a model which has process properties, data properties, and requirements on technology. Therefore e-module presents a holistic framework for deployment of e-business solutions and such e-module structure mandates an approach which requires reengineering of business processes and adoption of strong standardization that solves interoperability issues. E-module is based on principles of service-oriented architectures with guidelines for introduction into business processes and integration with ERP systems. Such an open source approach enables the spreading of compatible software solutions across any given country, thus, increasing e-business adoption. This paper presents a methodology for defining and building e-modules.

Typical Component

Component-based approaches generalize basic object-oriented implementations by allowing large collections of objects to be grouped together and externalized in terms of public interfaces. A typical component-based system will include a large number of interacting components. Service-Oriented Architecture (SOA) organizes a system in terms of components that communicate via services. Components publish services that they implement as business processes. Consequently, a change to a single component can have a ripple effect on the service-driven system. Component reconfiguration is motivated by the need to evolve the component architecture and can take a number of forms. The authors define a dynamic architecture as one that supports changing the behavior and topology of existing components without stopping, updating, and redeploying the system. This chapter addresses the problem of dynamic reconfiguration of component-based architectures. It proposes a reification approach that represents key features of a language in data, so that a system can reason and dynamically modify aspects of it. The approach is described in terms of a new language called µLEAP and validated by implementing a simple case study.
