Model-centric development is one of the hottest topics discussed in the software engineering field today. Combination of Model Driven Development and Model Driven Architecture can be extremely powerful for supporting the development cycle of the application. The use of these software methodologies within the Industrial Automation field allows meeting the requirement of current automation applications,...
Cheddar is a framework dedicated to the specification of real-time schedulers, and to their analysis by simulation. It is developed in Ada. Some parts of its modular architecture are generated by Platypus, a software engineering tool based on the STEP standards. Cheddar owns a dedicated specification language. It can also process AADL v1 specifications. In order to extend the scope of Cheddar to AADL...
At present, UML has gained comprehensively concern in computer science and engineering, and found wide application. To study the research situation and future of UML in China, this article firstly employed frequency statistics to count the frequency of 2940 papers related with UML area published from year 2001 to 2008 in Chinese famous CNKI database, then defined the high frequency keywords and their...
The application of robotic system has nowadays been vastly incorporated in many domains. To support customized demands, robotic embedded software oftentimes may face the variation challenges on hardware sensor, hardware assembling structure, and hardware platform. Basing on the perspective of software engineering, the paper endeavors to explore the embedded software architecture. We have concluded...
Web services are an emerging Service-Oriented Architecture technology to integrate applications using open standards based on XML. Software Engineering tools integration is a promising area since companies adopt different software processes and need different tools on each activity. Software engineers could take advantage of software engineering tools available as web services and create their own...
In a multi-site software development setting, creational and validational activities can be distributed and carried out by separate teams. An example of such a distributed development setup is when a system implemented in site A needs to be validated in a remote site B with regard to the component interaction rules dictated by the system architecture. In the current software engineering practice,...
Over the last decade, a large number of Method Engineering (ME) approaches have been developed to adapt information system methods (ISM) to specific situations of projects at hand. However, ME has not been yet, widely spread in the professional world. Our belief is that limitations such as the lack of standards, the proposal of proprietary solutions and an excessive emphasis on engineering issues...
A new breed of Web application, dubbed AJAX, is emerging in response to a limited degree of interactivity in large-grain stateless Web interactions. At the heart of this new approach lies a single page interaction model that facilitates rich interactivity. We have studied and experimented with several AJAX frameworks trying to understand their architectural properties. In this paper, we summarize...
Policy-based management (PBM) has been considered as a promising approach for design and enforcement of access management policies for distributed systems. The increasing shift toward federated information sharing in the organizational landscape, however, calls for revisiting current PBM approaches to satisfy the unique security requirements of the federated paradigm. This presents a twofold challenge...
