During an architectural evolution of a component-based software, certain quality attributes may be weakened. This is due to the lack of an explicit definition of the links between these non-functional characteristics and the architectural decisions implementing them. In this paper, we present a solution that aims at assisting the software maintainer during an evolution activity on his demand. I...

Quality evaluation is a challenging task in monolithic software systems, and is even more complex when it comes to Service-Oriented Software Product Lines (SOSPL), as it needs to analyze the attributes of a family of SOA systems. In SOSPL, variability can be managed and planned at the architectural level to develop a software product with the same set of functionalities but different degrees of...

We argue that it is useful to study classes of Multi-Agent System (MAS) architectures, corresponding to architectural styles in addition to particular architectures. In this work we focus on a particular abstraction level where MAS architectural styles are characterized according to properties, such as, the type of control used (from fully centralized to fully distributed), and the type of coor...

Software architects design systems to achieve quality attributes like security, reliability, and performance. Key to achieving these quality attributes are design constraints governing how components of the system are configured, communicate and access resources. Unfortunately, identifying, specifying, communicating and enforcing important design constraints – achieving architectural control – ...

Sharing the architectural knowledge of architectural analysis among stakeholders proves to be troublesome. This causes problems in and with architectural analysis, which can have serious consequences for the quality of a system being developed, as this quality might be incompletely or wrongly assessed. This paper presents a domain model, which can be used as a common ground among analysts and a...

CORBA is a commercial standard for distributed object computing which shows great promise in the development of distributed programs. Its interface description language (IDL) enables objects to be developed independently of the underlying programming language, operating system, or computer architecture on which they will execute. While this is suucient in many environments, programs deployed in...

Object-oriented software systems have a natural tendency to evolve. This can be due to many different reasons such as changing requirements, software maintenance, etcetera. Current trends even seem to indicate that continuously evolving systems will become the norm for most organisations. To cope with this fact, architectures and designs should be made as adaptable and reusable as possible. Thi...

The conceptual modelling of software architectures is of central importance for the quality of a software system. A rich modelling language is required to integrate the different aspects of architecture modelling, such as architectural styles, structural and behavioural modelling, into a coherent framework. We propose an ontological approach for architectural style modelling based on descriptio...

In this paper, we discuss software architectural design methods, especially that in the early phase of software development to find out the design direction for the software. In architectural design, we examine fundamental software structure considering the requirements on potential software that will be developed on the architecture, in terms of functionalities and quality attributes. Besides,...
