The following topics are dealt with:service development; service control; service-oriented architecture; business services; cyber-physical services; data-based services; service management; embedded services; service verification; and service analysis.
Current Web-service description languages like WSDL are very powerful and many topics, like how to describe the composition of Web-services, have received much attention by the scientific community. With the rise of RESTful Webservices, resources come to the focus of service developers, with the need to transfer many well understood problems to a new paradigm. RESTful services up to now are most commonly...
As the growth of IT spending has trended down to the mid-single digits in recent years, the IT services industry has continued to focus on productivity improvement to take out costs. While innovations in new service business and delivery models are keys to margin growth, service quality is ever more important to protect the client base. This paper reports end-to-end current practices in the enterprise...
Data as a Service (DaaS) emerges as a new trend for exchanging data between independent data owners and data users so that data can be acquired on demand through standard protocols across heterogeneous platforms. It is usually a user-interactive and iterative process to compose the services into various data-driven business scenarios of data acquisition, analysis, and other processing activities....
Nowadays, the mainstream of Web 2.0 Website services is in the REST style called RESTful Web service. RESTful services have been widely accepted by the public because of the usability and simplicity. Meanwhile, Web service technologies realize service-oriented architecture (SOA) successfully and are exploited in both industry and academia. Notably, service composition that can aggregate existing services...
In this paper, the service oriented software usability, which is defined in the ISO/IEC 9126 standards as a number of nonfunctional software quality characteristics, is shown to be measurable by given design principles. The purpose of the study is to develop an approach to (1) provide measurable indexes for usability characteristics and (2) obtain the measurable indexes from previously experienced...
Due to the advances in cellular devices and mobile technologies, now it has become possible to host Web Services (WS) on mobile devices. Web services have a broad range of service clients, whereas mobile phones have a large and expanding number of user bases. Therefore, combining these two trends by exploiting mobile devices as service providers is a promising next step. However, the usability, reliability,...
Current workflow engines, often based on WS-BPEL, are monolithic programs to orchestrate a business process or take part in choreography between partners. They cover aspects like the execution of the workflow description derived from the business process, the communication with external services, and the handling of errors. Both, the communication with services as well as basic error handling are...
The research of Web Services attracts the attentions of a lot of people in recent years. As a key technique in the development of Web Services, automatic Semantic Web Sevices composition is a problem that must be conquered. Since the similarity between Web Servicec and AI actions, AI planner is the most direct method to resolve this problem. However, due to the different application domain and the...
The introduction of software and infrastructure into the service oriented architecture (SOA) concept, created an increasing interest for the integration of license management mechanisms into such environments. In the new era, ruled by the concept to provide everything as a service, the realization of it for licenses is very challenging and of great importance, given that it affects directly the software...
A Web service choreography describes a global protocol of interactions among a set of cooperating services. For the dynamic composition, changing interconnections by channel passing between services is necessary. In this paper we use model checking technique for the verifying problems related to channel passing in choreography. We develop a framework: for each kind of property to be verified, we define...
Business documents exchanged in a service-oriented context play a crucial role in the definition of service interfaces. Only if both partners have a common agreement on the data exchanged, automated business interactions are possible. The United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) provides a reliable and interoperable solution for conceptual business document...
The purpose of this paper is to propose a service-oriented reverse reengineering that consists of re-documentation and design recovery. To understand the legacy system, we need to re-document the legacy system in a highlevel abstraction by using UML visual models through an initial reverse engineering. For this re-documentation, we propose a new re-documentation technique called 5W1H (Why, Who, When,...
Mobile Internet Device (MID), as a portable handheld device, becomes a strong candidate for client-side computing. Android is a mobile operating system, being accepted as the operating system and a platform for MID applications. However, MID has a limited resource and computing power, and Android has an architecture and its components which are not commonly found in other operating systems and platforms...
To obtain scalable performance and cost efficiency, there is a great demand for ??shared BPO (business process outsourcing)?? services. In analogy to the SaaS paradigm, this paper proposes an "organization as a service" (OaaS) model for shared BPO services. This model quantifies operational risks of sub-services taking into consideration the variability of human resource behavior. Based...
Service-oriented computing (SOC) has been adopted to manage complexity and develop robust software applications. SOC is mainly used for Web services or the application layer. As software complexity is increasing in an enormous speed, software design has become more challenging. Autonomic computing (AC) supports self-adaptation to manage complexity, improve performance, and/or increase reliability...
This study develops a service-oriented application that focuses on the supports of self-care activities for diabetic patients. Self-care is an area that is yet to be well supported by current healthcare systems. In designing innovative service model, service sector is reaching toward academics for theoretical assistance. A method of systemic approach is used in this study as the map for building a...
