As the properties of components have gradually become clearer, attention has started to turn to the architectural issues which govern their interaction and composition. In this paper we identify some of the major architectural questions affecting component-based software development and describe the predominant architectural dimensions. Of these, the most interesting is the “architecture hierar...

As the properties of components have gradually become clearer, attention has started to turn to the architectural issues which govern their interaction and composition.

Although considered to be incompatible, a combination of agile methods and architectural modelling could open a new perspective in software development. On the one hand, agile methods offer the flexibility required today. On the other hand, architectural modelling is considered as a pre-requisite for the systematic cross-project reuse and for the resulting increase in software developer product...

Web services allow the components of applications to be highly decentralized, dynamically reconfigurable. Moreover, Web services can interoperate easily inside an heterogeneous network environment. The vast majority of current available verification environments have been built by sticking to traditional architectural styles. Hence, they are centralized and none of them deal with interoperabili...

Architectural patterns are a fundamental aspect of the architecting process and subsequently the architectural documentation. Unfortunately, there is only poor support for modeling architectural patterns for two reasons. First, patterns describe recurring design solutions and hence do not directly match the elements in modeling languages. Second, they support an inherent variability in the solu...

Asynchronous and Synchronous interaction between humans and systems are commonly implemented using differentiated architectural elements. This causes a combination of components and connectors which expands architectural models making them more complicated. In This paper we describe a mechanism to combine both kinds of connections simplifying software architectures at the same time that they ca...

Register-Transfer (RT-) level netlists are said to be isomorphic if they can be made identical by relabeling RT-components. RT-netlists can be generated by architectural synthesis. In order to consider just the essential design decisions, architectural synthesis should consider only a single representative of sets of isomorphic netlists. In this paper, we are using netlist isomorphism for the v...

Architectural designs specify the components of a software system, their interfaces, and their interrelationships. Module Interconnection Languages (MILs) are useful for specifying architectural designs, but lack an intuitive visual representation similar to the visual design notations found in CASE tools. This paper presents a framework for formally de ning the syntax and semantics of language...

Hosts are often connected by multiple paths, but TCP restricts communications to a single path per transport connection. Resource usage within the network would be more efficient were these multiple paths able to be used concurrently. This should enhance user experience through improved resilience to network failure and higher throughput. This document outlines architectural guidelines for the ...

The architecture of an active DBMS determines both its functionality and the components that are required for its implementation. This chapter addresses rst some issues that have an impact on the architecture of an active database system, and presents the various architectural alternatives. The basic functions of an ADBMS are identiied and then related to the architectural alternatives. This ch...
