Component-based software development is becoming more generalized, representing a considerable market for the software industry. The perspective of reduced development costs and shorter life cycles acts as a motivation for this expansion. However, several technical issues remain unsolved before software component’s industry reaches the maturity exhibited by other component industries. Problems ...

Over the past 15 years there has been increasing recognition that careful attention to the design of a system’s software architecture is critical to satisfying its requirements for quality attributes such as performance, security, and dependability. As a consequence, during this period the field of software architecture has matured significantly. However, current practices of software architect...

According to IEEE, software quality is the degree to which software possesses a desired combination of attributes. Quality attributes have been of interest to the software community since 1970 and in the past few years this interest has increase. However, still is not clear how product quality should apply in the development process. The need to know what quality characteristics influence a spe...

Fat hardness/softness directly affects efficiency of processing and fat also contributes to the desirable eating attributes of meat. In terms of meat quality, fat quality attributes of colour, hardness and texture are important for certain markets. The quality of fat can markedly affect the carcase value at the wholesale level—particularly that for the Japanese market, which prefers soft white ...

Software quality is evolving beyond static measurement to a wider scope of quality definition. Previous studies have indicated the importance of human aspect in software quality. But software quality models have not included comprehensively this aspect together with the behavioural aspect of the quality. This research has proposed a Pragmatic Quality Factors (or PQF) as a software quality measu...

We present an empirical study of the impact of design patterns on quality attributes in the context of software maintenance and evolution. Our first hypothesis verifies software engineering lore: design patterns impact software quality positively. We show that, contrary to popular beliefs, design patterns in practice impact negatively several quality attributes, thus providing concrete evidence...

We address the fundamental question: what does it mean for data in a database to be of high quality? We motivate our discussion with examples, where traditional views on data quality are found to be unsatisfactory. Our work is founded on the premise that data values are primarily linguistic signs that convey meaning from their producer to their user through senses and referents. In this setting...

Cell and gene-based therapies represent a novel therapeutic modality that has the potential to provide a treatment option for a range of medical conditions. There are, however, numerous processing and manufacturing challenges that must be addressed before such therapies are considered commercially and clinically viable. A significant challenge associated with the manufacture of such therapies i...

Developers and designers always strive for quality software. Quality software tends to be robust, reliable and easy to maintain, and thus reduces the cost of software development and maintenance. Several methods have been applied to improve software quality. Refactoring is one of those methods. The goal of this paper is to validate/invalidate the claims that refactoring improves software qualit...
