With the shift to a service-oriented architecture, goals concerning the IT of an organization, such as an increased flexibility and maintainability, are expected to be attained. For this purpose, the building blocks of the serviceoriented architecture, the services, have to be designed that certain quality attributes, such as loose coupling or autonomy, are fulfilled. Existing design processes ...

ESM codes have mostly been written directly by scientists, as experts in the various geoscientific domains relevant for thesemodel. This contrastswith commercial forms of software development, where there is usually a clear division of labour between systems analysts, who determine what the system should do, and programmers, who are responsible for writing the code. Having scientists write thei...

In this paper we introduce a quality-driven architecture design (QAD) method with three phases: system analysis, conceptual architecture design and design of a concrete architecture. Architecture design phases produce an aspect of software architecture at two different levels of abstraction. System analysis provides a bigger picture of the software system and its properties. Conceptual architec...

Why has there been so little progress in the quantitative evaluation of those quality attributes concerned with software design? This paper seeks to provide an answer by arguing that progress is dependent on the adoption of a programme of cumulative empirical research. Such a programme consists of original empirical research, independent replication to investigate and verify original results, a...

John Morley [email protected] A system designer faces several challenges when specifying security for distributed computing environments or migrating systems to a new execution platform. Business stakeholders impose constraints due to cost, timeto-market requirements, productivity impact, customer satisfaction concerns, and the like. And users exercise power at the desktop over computing reso...

Research Article Rosanne Price Monash University [email protected] Graeme Shanks The University of Melbourne [email protected] It has been proposed that metadata describing data quality (DQ), termed DQ tags, be made available in situations where decision makers are unfamiliar with the data context, for example, in data warehouses. However, there have been conflicting reports as to t...

Semantic Web is an extension of current web in which the web resources are equipped with formal semantics about their interpretation for the machines. These web resources are integrated in the form of web information systems, and their formal semantics are normally represented in the form of web-ontologies. Using the database terminology, we can say that web-ontology of a semantic web system is...

2. "Engineering design" as an activity produces an "engineering design" as a product. This product is a representation of the physical product to be manufactured and is variously called the "design object", the "product model", or after the media the "engineering drawing." Since a craftsman is only as good as his tools, the quality of the design tools (e.g., representations, conventions, and ap...

Object oriented approach is one of the popular software development approach for managing complex systems with massive set of requirements. Unlike procedural approach, this approach captures the requirements as set of data rather than services. Further, class is considered as a key unit of the solution-domain with data and services wrapped together, representing architectural design of a basic ...

We develop an analytical framework to investigate the competitive implications of personalized pricing and quality allocation (PPQ), whereby rms charge di erent prices and o er di erent qualities to di erent consumers, based on their willingness to pay. We embed PPQ in a model of spatial di erentiation, and show how information about consumer preferences a ects multi-product rms' choices over p...
