A proposal for a set of attributes relevant for Web portal data quality

Abstract: Data Quality is a critical issue in today's interconnected society. Advances in technology are making the use of the Internet an ever-growing phenomenon and we are witnessing the creation of a great variety of applications such as Web Portals. These applications are important data sources and/or means of accessing information which many people use to make decisions or to carry out tasks. Quality is a very important factor in any software product and also in data. As quality is a wide concept, quality models are usually used to assess the quality of a software product. From the software point of view there is a widely accepted standard proposed by ISO/IEC (the ISO/IEC 9126) which proposes a quality model for software products. However, until now a similar proposal for data quality has not existed. Although we have found some proposals of data quality models, some of them working as "de facto" standards, none of them focus specifically on web portal data quality and the user's perspective. In this paper, we propose a set of 33 attributes which are relevant for portal data quality. These have been obtained from a revision of literature and a validation process carried out by means of a survey. Although these attributes do not conform to a usable model, we think that it might be considered as a good starting point for constructing one.

Preparing Students and Engineers for Global Software Development: A Systematic Review

Abstract: In recent years, the evolution of Global Software Development (GSD) has grown both rapidly and significantly, and although the efficiency of this new type of development has been proven, some challenging issues must still be confronted. Of all these, our research line is focused on designing the specific training that members of virtual teams must receive. Universities and companies therefore need to design training schemas to deal with the specifics of GSD, which are principally related to communication difficulties and time and cultural differences. In this work we present the findings of a Systematic Literature Review in the field of GSD training and teaching. Our intention is twofold: on the one hand we wish to discover the existing strategies and proposals available up to the present day, and on the other hand we wish to identify the open challenges, that will be helpful for practitioners and researchers in the future.

IQM3: Information Quality Management Maturity Model

Abstract: In order to enhance their global business performance, organizations must be careful with the quality of their information since it is one of their main assets. Analogies to quality management of classical products demonstrate that Information Quality is also preferably attainable through management by integrating some corresponding Information Quality management activities into the organizational processes. To achieve this goal we have developed an Information Quality Management Framework (IQMF). It is articulated on the concept of Information Management Process (IMP), based on the idea of Software Process. An IMP is a combination of two sub-processes: the first, a production process, aimed to manufacture information from raw data, and the second to adequately manage the required Information Quality level of the first. IQMF consists of two main components: an Information Quality Management Maturity Model (IQM3), and a Methodology for the Assessment and Improvement of Information Quality Management (MAIMIQ), which uses IQM3 as a reference model for the assessment and for the improvement goal of an IMP. Therefore, as a result of an assessment with MAIMIQ, an IMP can be said to have raised one of the maturity levels described in IQM3, and as improvement goal, it would be desirable to achieve a higher maturity level. Since an Information System can be seen as a set of several IMPs sharing several resources, it is possible to improve the Information Quality level of the entire Information System by improving the most critical IMPs. This paper is focused only on describing the foundations and structure of IQM3, which is based on staged CMMI.

A Data Quality Measurement Information Model Based On ISO/IEC 15939.

Abstract: Measurement is a key activity in DQ Management. Through DQ literature, one can discover a lot of proposals contributing somehow to the measurement of DQ issues. Looking at those proposals, it can be found out that there is a lack of unification of the nomenclature: different authors call to the same concepts in different way, or even, they do not explicitly recognize some of them. This may cause a misunderstanding of the proposed measures. The main aim of this paper is to propose a Data Quality Measurement Information Model (DQMIM) which provides a standardization of the referred terms by following ISO/IEC 15939 as a basis. This paper deals about the concepts implied in the measurement process, not about the measures themselves. In order to make operative the DQMIM, we have also designed a XML Schema which can be used to outline Data Quality Measurement Plans.

Out of the Crisis

Abstract: According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Web Services Architecture

Abstract: Microsoft has promoted ASP.NET’s new web services more than almost any other part of the.NET Framework. But despite their efforts, confusion is still widespread about what a web service is and, more importantly, what it’s meant to accomplish. This chapter introduces web services and explains their role in Microsoft’s vision of the programmable web. Along the way, you’ll learn about the open standards plumbing that allows web services to work and removes some of the confusion surrounding technical terms like WSDL (Web Service Description Language), SOAP, and UDDI (universal description, discovery, and integration).

Systematic Literature Reviews in Engineering Education and Other Developing Interdisciplinary Fields

Abstract: Background In fields such as medicine, psychology, and education, systematic reviews of the literature critically appraise and summarize research to inform policy and practice. We argue that now is an appropriate time in the development of the field of engineering education to both support systematic reviews and benefit from them. More reviews of prior work conducted more systematically would help advance the field by lowering the barrier for both researchers and practitioners to access the literature, enabling more objective critique of past efforts, identifying gaps, and proposing new directions for research. Purpose The purpose of this article is to introduce the methodology of systematic reviews to the field of engineering education and to adapt existing resources on systematic reviews to engineering education and other developing interdisciplinary fields. Scope/Method This article is primarily a narrative review of the literature on conducting systematic reviews. Methods are adapted to engineering education and similar developing interdisciplinary fields. To offer concrete, pertinent examples, we also conducted a systematic review of systematic review articles published on engineering education topics since 1990. Fourteen exemplars are presented in this article and used to illustrate systematic review procedures. Conclusions Systematic reviews can benefit the field of engineering education by synthesizing prior work, by better informing practice, and by identifying important new directions for research. Engineering education researchers should consider including systematic reviews in their repertoire of methodologies.
