Service-oriented architecture is a recent conceptual framework for service-oriented software platforms. Architectures are of great importance for the evolution of software systems. We present a modelling and transformation technique for service-centric distributed software systems. Architectural configurations, expressed through hierarchical architectural patterns, form the core of a specificat...

The Cantonese sentences in (2) illustrate these claims. They denote past events and there are no markers attached to the verb (subclaim (1a)). Subclaim (1b) is illustrated by the minimal pair in (2b) and (2c): the latter describes a current situation and the former, with the temporal adverb ML FLQ ‘formerly’, describes a past event. (The superscripts in the Cantonese renderings are tone markers.)

Typical approaches to design patterns present them in the catalog form. For undergraduate students this abstract description of the pattern makes it even more difficult to understand its purpose and need. In this paper we describe a tool used at a university course to enable the students to learn architectural patterns by looking at code. The tool presented in this paper shows the solution to a...

In the development of groupware systems a well designed communications infrastructure is required, due to the high complexity of the communication scenario. Also, the design and implementation of coordination and collaboration mechanisms depends on the communications infrastructure. Actually there are no well known guidelines to design this infrastructure. Therefore, this paper proposes an arch...

TRADITIONALLY, SOFTWARE architects were entrusted with making “decisions that are costly to change.”1 Because these decisions often had to be made early in the project, architects drew on their experience and ability to abstract to get them right. Repeated project cost and timeline overruns have demonstrated, though, that trying to plan all features and decide the system structure early in a pr...

In this paper we introduce a content-oriented scheme for protocol studies of designers and demonstrate its benefit for CAAD research. The structure of the coding scheme is described. We discuss how this method can benefit CAAD research and its differences from the process-oriented method used previously. With this method we analyze data to describe the design process as the combination of senso...

Architecture is the set of principal design decisions about a software system. In practice, new architectural decisions are added and existing ones reversed or modified throughout a system’s lifetime. Frequently, these decisions deviate from the architect’s well-considered intent, and software systems regularly exhibit increased architectural decay as they evolve. The manifestations of such ill...

banjarmasin is known as a tidal waterfront city and it is called city of a thousand rivers. thecity level was approximately -16 cm below the sea level and almost a swamp-land. the urbanization and the citydevelopment programs have changed the city’s physical and spatial plan from a wetland to a mainland structure. theissues of the city's transformation have changed the city structure from ...
