Code generation from models is a core activity in model-driven development (MDD). For complex systems it is usually impossible to generate the entire software system from models alone. Thus, MDD requires mechanisms for integrating generated and handwritten code. Applying such mechanisms without considering their effects can cause issues in projects with many model and code artifacts, where a sound...
This papers content is about evaluating how to utilise hybridisation of digital communications in order to secure sustainable approaches based on green buildings and infrastructure. The challenges associated with environmental and social impacts of building designs have created socio-economic impacts on our communities. There is an extensive push for “technical optimism” while engaging the communities...
Software modernization often involves complex code transformations that convert legacy code to new architectures or platforms, while preserving the semantics of the original programs. We present the lessons learnt from an industrial software modernization project of considerable size. This includes collecting requirements for a code-to-model transformation, designing and implementing the transformation...
Because modern engineering products require more and more functionality, the models used in the design of these products get larger and more complex. A way to handle this complexity would be a suitable mechanism to modularize models. However, current approaches in the Model Driven Engineering field have limited support for modularity. This is the gap that our research addresses. We want to tackle...
The advent of multi-core systems set off a race to get concurrent programming to the masses. One of the challenging aspects of this type of system is how to deal with exceptional situations, since it is very difficult to assert the precise state of a concurrent program when an exception arises. In this paper we propose an exception-handling model for concurrent systems. Its main quality attributes...
We present our Abstraction Layer Object-Oriented Architecture (ALOOA) and its application to Motion Control. This layer provides a higher level of abstraction than that provided by the well-known PLCOpen library. In fact, the proposed approach uses OO features (i.e. methods, inheritance, and polymorphism) which allow us to define a generic device of motion control, whose hardware-dependent implementation...
Looking for a complete modular software development paradigm, this article presents Join Point Interface JPI Feature Models, in the context of a JPI and Feature-Oriented Programming FOP symbiosis paradigm. Therefore, this article describes pros and cons of JPI and FOP approaches for the modular software and software product line production, respective; and highlights the benefits of this mixing proposal;...
The emergence of new applications that need to share information between different sources of information, such as e-learning, e-commerce, e-government, and electronic libraries requires interoperability between information systems. The information systems are designed and developed by different organizations to be autonomous and heterogeneous sources which lead to multiple structuring formats and...
Model-driven software engineering reduces the effort of developing software by replacing low-level programming with the construction of high-level executable models. Refactoring improves the structure of software artifacts without changing external behavior. Originally, refactoring was developed for and applied to (object-oriented) programs. In the context of model-driven software engineering, refactoring...
Our experience with email-based marketing campaigns (or short: “Microservices”) showed that they are an intersecting set of a) projects and processes and b) technology and creativity. Their properties of fixed due date, fixed scope and at the same time fixed duration render classical management methodologies unfeasible. The same applies to the supporting enterprise infrastructure architecture, where...
Cyber-human systems support the increasingly complex and coupled relationships between humans and machines. This paper demonstrates that within a state based behavioral view that supports state refinement, the addition of event refinement is a natural way to define complex behavior in these systems. The paper provides a meta-model of terms and relationships which the systems analyst can use to create...
This work presents a methodology based on simulator developers to be applied in several courses as well as research activities. This proposal is also based on “The Cathedral and the Bazaar” lessons. First, good programmers know what to write, however great ones know what to rewrite. Students could learn by developing new components to be added to the current simulator. Second, any tool should be useful...
With the growing complexity of complex software-intensive systems, some new features emerge such as logical complexity, boundary erosion and failure normalization, which bring new challenges for software dependability assurance. As a result, there is urgent necessity to analyze the failure mechanism of these systems in order to ensure the dependability of complex software-intensive systems. Research...
In this paper, we propose a domain-oriented, Java specification language that uses executable Java's annotations to specify the state space of each domain class in the model (incl. Class, association, and domain constraint of each attribute.) We argue that, compared to the state-of-the-art, our language provides several benefits for both designer and programmer of Java programs. For designer, the...
Model-View-Controller (MVC) is an established architectural design pattern for developing interactive, object-oriented applications. Numerous MVC-based application development approaches have been proposed in the literature, the more recent of which incorporate the domain-oriented design approach. From the architectural design view point, however, domain-oriented design has only been applied at the...
Identifying fault prone modules at the very early stage of software development life cycle is very much necessary. This helps software developers to concentrate more on quality assurance, use the man power in proper perspective and mainly reduce the fault removal cost to be in-cured for the software system being developed. In literature, it is found that numerous authors have come up with cost based...
The development of software products is currently being expanded to be based on web applications. Due to the time constraints, software design and development for web applications are driven. It leads the software or applications become more complex. Identifying impacts of changes or relations takes a lot of time and effort. One challenge is to enable traceability on software artefacts created during...
Encapsulation in object oriented models refers to the bundling of data with the methods that operate on that data, it is used to hide the values or state of a structured data objects and preventing unauthorized parties' direct access to them. Access control mechanism in information systems is the process of mediating every request to resources and determining whether the request should be granted...
In the development of PLC software for automated Production Systems the method copy & paste is commonly used. However, this method leads to various disadvantages. To avoid these disadvantages, a parameter-based concept for planed reuse is presented in this paper. By means of the Siemens PLC software of an automated warehouse, the concept is defined and evaluated. In a first step, the PLC software...
This paper presents a system able to generate an abstraction framework over a RDF-based, semantic triplestore, offering Object-Oriented Application Programming Interfaces to be made available for external applications. The system only requires a well-defined RDF schema and a minimal supervision by the user, and is able to produce all of the components of the API framework at their different layers,...
