Service Oriented Architectures (SOAs) are increasingly being used to support the information infrastructures of organizations. SOAs are dynamic and evolve after deployment in order to adapt to changes in the requirements and infrastructure. Consequently, traditional validation approaches based on offline testing conducted before deployment are not adequate anymore, demanding for new techniques that...
Requirements for business processes can change over time. Adapting a process to meet the changed requirements is not always possible, especially for long running processes, where stopping the execution of process instances might be necessary and/or instance migration or compensation scenarios must be implemented. Adaptations for processes can be described in a generic way using adaptation patterns...
As a service-based language, WS-BPEL (the Web service Business Process Execution Language) is widely adopted into enterprise solutions. However, because of the intrinsic flexibility and dynamism of the Web services it used, its behavior couldn't be foreseen until it is running, runtime monitoring is needed. The paper proposed a novel solution to the problem of monitoring Web services instances implemented...
The scope of IMS QoS management is limited to session initialization and QoS provisioning, thus lacking follow-up or monitoring functionality; neither does it tackle user differentiation. A tempting approach would be to leverage the standard 3GPP architecture by Assurance services based on TMForum's eTOM framework. This scenario would however expose a set of general business processes and would require...
Due to their different target applications business and scientific workflow systems provide different sets of features to their users. Significant amount of research is currently being done to employ the business workflow technology in the scientific domain. This usually means extending the workflow language and thus the modeling tool and execution engine. In this paper we aim to bring business and...
WPS (web processing service) is the specifications launched by OGC organizations for dealing with space data, which is different from the conventional Web Service. There aren't dedicated workflow environment for WPS service framework, and support of workflow environments in WPS application is the key technical challenges. Some of the workflow environment, such as Shark, still lack of effective implementation...
As the amount of data generated by today's pervasive environments increases exponentially, there is a stronger need to decipher the important information that is hidden among it. By using complex event processing, we can obtain the information that really matters to our organization and use it to improve our processes. However, even when this information is retrieved, business processes remain static...
IMS (IP Multimedia System) facilitates a rapid deployment of new services enable new revenue streams for service providers, and improves the operating efficiency of the network by a convergence of heterogeneous into an existing IP network. In addition, it enables operators to simultaneously meet the requirements of fixed and mobile telephony. Because IMS “standardization” is limited to architecture,...
This paper proposes a Diseases Notification System which is designed using a SOA pattern. Disease notification is an import component of the disease control systems. A successful diseases notification system will deliver positive effects for human beings. The proposed system is designed and implemented by use of the Business Process Execution Language for the business process layer and Enterprise...
SaaS and multi-tenancy has become a trend which gets more and more popularity. On this basis, how to monitor the information of SaaS service process and the instance information of every service of the interaction is an important problem. Based on the model of interaction-oriented SaaS application support for multi-tenancy, this paper proposes a mechanism for tracking the business instance of SaaS...
The agility of SOA (service-oriented architecture) can response changes of business process effectively. To meet the requirements of rapid building business system for personality and high-speed changes based on business model, SOA was introduced. In this paper, firstly, the information system architecture based on SOA was built, moreover, Ajax (asynchronous Javascript and XML) technology was adopted...
Dynamic service composition is suitable for on-demand business requests. For autonomic computing, service composition needs to deal with runtime environment faults, but also with business constraint violations which result from business requirements. We propose an approach for integrated handling of business constraint violations and runtime environment faults for dynamic service composition.We introduce...
In this paper we introduce a new modeling tool for constraint handling in the area of workflow technology. The constraint handlers can be used to improve the quality of business processes but without changing already existing business logic. Todays workflow languages provide no possibility to model constraints and the actions in case the constraints get violated explicitly. Fault and event handling...
Globalization leads to an efficient new business paradigm generally known as collaborative virtual enterprise (CVE) which demands flexible service orchestration and robust workflow execution. As two major service orchestration strategies, OWL-S and BPEL have their own strength and deficiencies. To meet the challenge in CVE, in this paper, we propose a workflow execution system (WES) that takes advantage...
WS-BPEL is the standard to define executable business processes in a Web service world. Numerous commercial and open source BPEL engines exist on the market today that allow the execution of process models defined in BPEL. However, these execution engines only provide access to process model and process instance data in terms of proprietary APIs. In this paper we present an approach that models BPEL...
SOA (service-oriented architecture) solution model involves SOA associated reference architecture, e-commerce patterns, methodologies and best practices ranging from the beginning to the end of a complete SOA project. A new solution model is presented. Service is the kernel and process is the breakthrough point of business innovation in this model. A series of widely acceptable standards, such as...
