Software architecture is considered one of the most important indices of software engineering today. Software Architecture is a technical description of a system indicating its component structures and their relationships, and is the principles and rules governing designing. The success of the software depends on whether the system can satisfy the quality attributes. One of the most critical as...

Art historians and critics have defined the style as common features appeared in a class of objects. Abstract common features from a set of objects have been used as a bench mark for date and location of original works. Common features in shapes are identified by relationships as well as physical properties from shape descriptions. This paper will focus on how the computer recognises common sha...

The codification of software architectural decisions made to address recurring software development challenges results in architectural styles. The Alfa framework provides a small set of architectural primitives for systematically specifying styles and style-based architectures for networkbased systems. In this paper, we formalize Alfa’s primitives in a compositional theory of styles and softwa...

RESTful Web services are software services which are published on the Web, taking full advantage and making correct use of the HTTP protocol. This chapter gives an introduction to the REST architectural style and how it can be used to designWeb service APIs. We summarize the main design constraints of the REST architectural style and discuss how they impact the design of so-called RESTful Web s...

Both the IRIS-DNS System and the PORTAL-DOORS System share a common architectural style for pervasive metadata networks that operate as distributed metadata management systems with hierarchical authorities for entity registering and attribute publishing. Hierarchical control of metadata redistribution throughout the registry-directory networks constitutes an essential characteristic of this arc...

Software engineers use abstraction to better understand, model and reason about the surrounding world. Recently Architecture Description Languages (ADLs) introduced new levels of abstraction with potential use at runtime to support system evolution. In this paper we propose the FORMAware architecture that blends run-time architectural representation with a reflective programming model to addres...

Reuse of large-grain software components offers the potential for significant savings in application development cost and time. Successful reuse of components and component substitutability depends both on qualities of the components reused as well as the software context in which the reuse is attempted. Disciplined approaches to the structure and design of software applications offers the pote...

Representational State Transfer (REST) is a software architecture style for distributed systems such as the Internet first introduced by Fielding in his doctoral thesis in 2000. REST defines a set of principles defining how resources are defined and addressed in a networked environment. The most known implementation of REST is HTTP. REST advocates use of simple course grained operations (PUT, G...

This paper proposes a computational model of design that attempts to capture within a social context two important aspects of style: 'content' and 'manner'. We present a characterisation of style for the artefact based on a framework that consists of information theoretic measures. We discuss the benefits the study of social networks offers a computational analysis of both aspects of style. It ...

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. Also push-based solutions from the distributed systems are being adopted on the web for Ajax applications. The field is, however, characteri...
