Synchronous groupware systems allow physically separated users to interact with one another and with shared computational objects in real time. Such systems are problematic to build since their user interfaces must support multiple, concurrent users, and both their application logic and their user interfaces must be distributed across multiple platforms. This survey explores the range of softwa...

Software architectural evaluation becomes a familiar practice in software engineering community for developing quality software. Architectural evaluation reduces software development effort and costs, and enhances the quality of the software by verifying the addressability of quality requirements and identifying potential risks. There have been several methods and techniques to evaluate softwar...

When we apply the mechanisms of an object-oriented language we form concrete architectures over some domain. Over time we identify recurring patterns and transform the concrete architectures into more general architectural abstractions. Such abstractions are then used in combination with the language mechanisms to form other kinds of concrete architectures in diagrams and programs: we apply a c...

Multiuser interactive systems allow physically separated users to interact with one another and with shared computational objects in real time. Such systems (also called synchronous groupware) are problematic to build since their user interfaces must support multiple, concurrent users, and both their application logic and their user interfaces must be distributed across multiple platforms. This...

A data processing network is as a set of (software) components connected through communication channels to apply a series of operations on data. Realization and maintenance of large-scale data processing networks necessitate an architectural approach that supports analysis, verification, implementation and reuse. However, existing tools and architectural styles fall short to support all these f...

Web services have received widespread attention and acceptance in the software engineering community. Automatic composition of services, to meet user’s requirements, is a powerful mechanism to ensure satisfaction of varied needs and thus enable the vision of Web services. Although Web services are equipped with the fundamental concepts and supporting technologies, the architectural style of the...

We propose a mathematical semantics for event-based architectures that serves two main purposes: to characterise the modularisation properties that result from the algebraic structures induced on systems by this discipline of coordination; and to further validate and extend the categorical approach to architectural modelling that we have been building around the language CommUnity with the “imp...
