At present, few methods of creating conceptual architecture have been proposed. What's more, they can't meet the requirements of dynamic Internet environment or software reuse. This paper comes up with a new method of generating conceptual architecture based on ontology, feature model and component in which a new feature meta-model is also been come up with. In particular, this architecture can adapt...
Enterprise JavaBeans (EJB) is a component technology commonly used for enterprise application development. Recent EJB 3.0 specification involves interceptors, a mechanism providing means to dynamically introduce additional behavior into the execution of a bean. As multiple interceptors can be applied to the same bean, and the order of interceptor invocation can be affected by a variety of specification...
Business process modeling notations are used in requirements engineering to specify business processes that should be supported by the system under development. Comparisons of business process modeling notations with regard to their concepts do exist, but to our knowledge, little evaluation has taken place regarding their effectiveness and efficiency for typical requirements engineering tasks. Therefore,...
This paper proposes and illustrates an approach to identify and specify requirements on information-based business services and their associated derived software services. The approach proposes first to identify business services by modeling business requirements using the goal oriented modeling notation i*. Then, in a second phase, the identified services are refined according to these requirements...
With the loose coupling and dynamic attributes of Web service, the implementation behavior may be different from original requirement, so itpsilas essential to implement the run-time monitoring. Monitoring analyzes the conformance of a Web service to the requirements. This paper gives a novel monitoring prototype framework. It introduces WS-policy to express the userpsilas monitoring requirement on...
To reduce the practicing defects in ration unified process, this paper introduces a new requirement modeling process, which is based on the analysis of rational unified process with the combination of agile modeling technique. Contents of this process includes: getting the requirement in a general way, planning the developing schedule according to the requirement priority and simplifying requirement...
The complexity of today's software systems is constantly increasing. As a result, requirements for these systems become more comprehensive and complicated. In this setting, requirements engineers struggle to capture consistent and complete requirements of high quality. We propose a feedback-centric requirements editor to help analysts controlling the information overload. Our HeRA tool provides analysts...
A decision information system (DIS) is a specific component of information system specialized in the support of decision-making by means of online analytical processing tools. Data warehouses (DW), at the core of DIS, integrate and historize collections of data often designed starting from the operational components of the Information Systems (IS). Methods, techniques and tools widely used in the...
Workflow technologies automate, totally or partially, the business processes. Such technologies use standard languages, like BPMN, to model business processes, BPMN. On the other hand, from the software engineering, OMG has defined a metamodel for the software process engineering (SPEM). This metamodel is used for describing a concrete software development process. The objective of this research work...
The capability to provide a platform for flexible business services in the air traffic management (ATM) domain is both a major success factor for the ATM industry and a challenge to integrate a large number of complex and heterogeneous information systems. Most of the system knowledge needed for integration is not available explicitly in machine-understandable form, resulting in time-consuming and...
In today's continuously changing markets newly developed products often do not meet the demands and expectations of customers. Research on this problem identified a large gap between developer and user expectations. Approaches to bridge this gap are to provide the developers with better information on product usage and to create a fast feedback cycle that helps tackling usage problems. Therefore,...
Traditional research of software components mainly aims to components at the level of program and source code, due to which the coupling degree between the components and the runtime environments is hard to lower, thereby limiting the reuse ability of the component. The application level components containing comparatively integral granularity of business function are more suitable for a larger scale...
A business viewpoint on the system distinguishes a "source" model and a "target" model. The "source" model must reflect the system (and its environment) that currently exists and is under investigation. Requirements for systems reflect business ownerspsila, managerspsila and userspsila needs related to the "target" model. Consistency between the "source"...
Supporting business services through Web service compositions (WSC) as part of service-oriented architectures involves various runtime monitoring requirements. The implementation of these requirements results in additional development activities. Due to the lack of standards for treating such WSC monitoring concerns, a corresponding development approach has to deal with a variety of specific technologies...
Business processes are increasingly complex and open because they rely on services that are distributed geographically and across organizations. As a result, they are prone to several points of failure. Monitoring, therefore, remains an important concern. We describe services monitoring support that integrates monitoring into common development activities. A flexible monitoring toolkit, REQMON, is...
