Quick Abstract

The use of Web portals to carry out on-line transactions is continuously increasing. This paper studies this type of Web portals (which we have denominated as Commercial Interaction) from the perspective of data quality, since we consider that this is an essential element if Web portals are to be competitive and their use is to be boosted. The quality of data in a Web portal is determined on the basis of a set of data quality characteristics. However, we have established that some data quality characteristics are more important than others according to various user profiles, based on demographic aspects (gender, age range, level of studies and type of organisation). In order to do that, Commercial Interaction Web portal users were surveyed and, as a result of that, three different user profiles were identified. This paper describes the survey development and the generation of the user profiles.

Quick Abstract

Web portals facilitate access to data on the Internet. Their use and quantity have increased, which has led to the need to satisfy user preferences in order for them to continue on the market. One competition-based strategy is to provide an adequate quality of service, and one of the key factors in this is the quality of the data provided by the Web portal. Bearing this in mind, we have defined a Data Quality (DQ) Model for Web portals. This model is composed of 42 DQ characteristics which are organized into two points of view and four DQ categories. In this paper we present work which is based on the statistical study of users’ opinions of one of the characteristics in the model – the Intrinsic DQ category. Our objective is to determine which characteristics in the Intrinsic category will be most relevant as regards the users’ gender, age range, level of studies and knowledge of computing, thus allowing us to verify that, according to the aforementioned parameters, the importance of some characteristics varies with regard to others. For example, women place more importance upon Credibility, while men view the Accessibility of the data in Web Portals as being more important.

Quick Abstract

Nowadays, Web portals serve as an important means to access information. It is common for users to use information obtained from the web to carry out their daily tasks. These users need to ensure that this information suits their needs. PDQM (Portal Data Quality Model) is a model that assesses the quality of portal data. PDQM has been defined in such a way that every time that one wishes to evaluate a different portal context, a specific configuration of the model must be used. In an attempt to go beyond this limitation and with the idea of making PDQM a more generic model, we have adjusted it to be applied to vortals, the largest category of portals. This article describes the first phase of adapting PDQM.

Quick Abstract

The global software development poses several challenges in software engineering, particularly in the elicitation stage, owing to the problems of communication and coordination which are caused when teams are geographically distributed. For a successful requirements elicitation in a global development environment, it is necessary to rely on professionals who are capable of confronting the challenges that arise in this environments such as: cultural differences, distributed communication and coordination. In order to develop in software engineers the skills suitable to face these challenges it is first necessary to discover which competencies or skills they should have or develop. In this work we describe an analysis carried out with this goal, therefore we propose a list of competencies desirable by a requirements elicitation specialist, which have been obtained from a review of the related literature. We also comment on certain useful strategies in the teaching of these competencies and propose the usage of a simulation environment for their development.

Quick Abstract

The requirement elicitation stage is that which is most critical in the development of a software product. However, this stage is not covered on teaching courses with the required depth, nor is invested the necessary time in training students and practitioners in these tasks. There is currently a trend towards global software development (GSD) which complicates the process of elicitation requirements since, for instance, communication is more difficult because stakeholders are geographically distributed. Moreover, the elicitation in GSD involves a variety of characteristics that are not often taught in software engineering courses. This paper presents some of the most important factors which may affect elicitation in GSD. Furthermore, we propose techniques with which to help students and software engineers to develop some of the skills needed to carry out the elicitation process in GSD.

Proceedings of WOSIS 2007/ICEIS, ISBN: 978-972-8865-96-2

Quick Abstract

MDA is an approach based on the transformation of models for software development. It is complemented with QVT as a language for transformations specifications. This approach is being paid much attention by researchers and practitioners since it promotes the early specification of requirements at high levels of abstractions, independently of computation, that will be later part of models closer to the software solution. Taking into account this approach, we can create business process models incorporating requirements, even those of security, that will be later part of more concrete models. In our proposal, based on MDA, we start from secure business process specifications and through transformations specified with QVT, we obtain use cases and security use cases. Such artifacts complement the first stages of an ordered and systematic software development process such as UP.

Quick Abstract

The technological advances and the use of the internet have favoured the appearance of a great diversity of web applications, among them Web portals. Through them, organizations develop their businesses in a highly competitive environment. One decisive factor for this competitiveness is the assurance of its data quality. In previous works, a data quality model for Web portals has been developed. The model is represented as a matrix that links the user expectations of data web quality to the portal functionalities. Into this matrix a set of 34 attributes where classified. However, the quality attributes on this model have not an operational structure, necessary to be used actual assessment. In this paper we present how we have structured these attributes by means of a probabilistic approach, using Bayesian Networks. The final objective is to use the Bayesian network obtained for evaluating the quality of a data portal (or a subset of its characteristics).

Proceedings of WOSIS 2006/ICEIS, ISBN: 978-972-8865-52-8

Quick Abstract

Business Processes are a crucial issue for many companies because they are the key to maintain competitiveness. Moreover, business processes are important for software developers, since they can capture from them the necessary requirements for software design and creation. Besides, business process modeling is the center for conducting and improving how the business is operated. Security is important for business performance, but traditionally, it is considered after the business processes definition. Empirical studies show that, at the business process level, customers, end users, and business analysts are able to express their security needs. In this work, we will present a proposal aimed at integrating security requirements and role identification for RBAC, through business process modeling. We will summarize our UML 2.0 profile for modeling secure business process through activity diagrams, and we will apply this approach to a typical health-care business process.
