In this paper, we discuss a technology as an industrial application of service-oriented engineering. The technology accomplishes continuous service in a wireless communication system.
Media content has become the major traffic of Internet and will keep on increasing rapidly. Various innovative media applications, services, devices have emerged and people tend to consume more media contents. We are meeting a media revolution. But media processing requires great capacity and capability of computing resources. Meanwhile cloud computing has emerged as a prosperous technology and the...
Modern organizations increasingly depend heavily on information stored and processed in distributed, heterogeneous data sources and services to make critical, high-value decisions. Service-oriented systems are dynamic in nature and are becoming ever more complex systems of systems. In such systems, knowing how data was derived is of significant importance in determining its validity and reliability...
Component Business Models (CBM) and manually synthesized heat maps have been used successfully by IBM Global Business Solutions to develop logical models that assist strategic decision-making. A key aspect of CBM is the layered intra-enterprise approach that identifies Execution, Control and Direction. However, the performance relationships between these layers can be a challenging to compute algorithmically,...
Cloud Storage systems provide user a safe and consistent place to save user's valuable data and documents. However, user's files are not encrypted on some open source cloud storage systems, such as Hadoop and Sector. The storage service provider can easily access the user's files. This brings a big concern about user's privacy. This paper describes a cloud storage system named YI Cloud. This system...
Enterprise Architecture (EA) Modelling aims to analyze an organization in terms of its components, IT systems and business processes. Current modelling approaches are based on Service Oriented Architecture (SOA) whereby components publish interfaces of operations that are used via message passing. It has been argued that SOA leads to tight coupling between components and does not handle complex component...
Cloud computing not only changes today's computing infrastructure, but also alters the way of obtaining computing resources, managing and delivering software and services. Meanwhile, cloud computing brings new issues, challenges, and needs in performance testing, evaluation and scalability measurement due to the special features of cloud computing, such as elasticity and scalability. This paper focuses...
Generating realistic test data is a major problem for software testers. Realistic test data generation for certain input types is hard to automate and therefore laborious. We propose a novel automated solution to test data generation that exploits existing web services as sources of realistic test data. Our approach is capable of generating realistic test data and also generating data based on tester-specified...
In a cloud computing environment, both the client and the provider need assurances that service interactions are in accordance with the service agreement (contract). It should be possible to encode a contract as a set of executable business policies that can be evaluated by either party for controlling service interactions. Naturally, it is important to verify the correctness properties of such a...
The two main aspects of the web service composition problem are control flow and data mismatches. Several approaches have been reported in the literature to tackle the former; while the latter, and equally relevant aspect for the correct compositional behavior, has either been ignored or addressed to a very limited extent. This paper describes a formal approach based on model checking, that guarantees...
According to the analysis of business process modeling technology and business process execution technology, a business process modeling framework named REPC (Rule-Merged Event-driven Process Chain) has been proposed to solve lack of process semantics such as business rule in transformation from business process modeling to business process execution. Through service-oriented Enterprise Resource Meta-model...
Scientific workflows normally consist of multiple applications acquiring and transforming data, running data intensive analyses and visualizing the results for scientific discovery. In this paper, we present our application of Service-Oriented Architecture (SOA) to compose and deploy systems biology workflows. In developing this application, our solution uses MeDICi a middleware framework built on...
Mashups are web application hybrids built from usually independent online services and information sources, commonly for purposes that differ from the original reasons those services were developed in the first place. The intent is usually to make data more useful, often through visualisation, combination, aggregation or the application of distributed expertise. Mashups rely on APIs to leverage content...
To achieve large scale reuse and economy of scale, software are wrapped into services and migrated to the cloud platform. As a result, the quality of software services are affected by many third party components such as infrastructure services and platform services. In the collaborative framework, the stake-holders may have distinct, even contradictive, quality objectives. It is necessary to build...
Standardized business documents are a prerequisite for successful information exchange in electronic business transactions. The United Nations Centre for Trade Facilitation and eBusiness (UN/CEFACT) provides a conceptual modeling approach, called Core Components, used by Business Partners (BPs) for defining business document models (BDMs). These BDMs are essential for defining service interfaces in...
