Abstract
Web accessibility is growing in importance as each day goes by. Alongside this growth, is also the need for access to web resources, by those with some sort of disability. The web is very important for spreading information and for the interaction between the various society elements. Given this, it is essential that the web presents itself as a totally accessible resource, so that it can help disabled citizens in their integration within society. This obligation should be greater for enterprises where the web is used as a marketing and business platform. With this paper we would like to present a study with indicators regarding the accessibility levels of Portuguese enterprises websites and, we would also like to present a brief comparison between the accessibility levels of the 1000 largest Portuguese enterprises websites and the accessibility levels of the 1000 best Portuguese SMEs websites.

Abstract
It is imperative for an organization to identify potential constraints to e-business in order to minimize the risk derived from its c-business initiative. Hence, in this paper, we have used a maturity stage model (Stages Of Growth Model for c-business SOGe) to identify the maturity stage of the biggest Portuguese enterprises and to report the findings of a study that sought to explore a range of constraints that the literature suggests influences c-business evolution, so that organizations could be better equipped in anticipating any difficulties while in progress through their. e-business initiatives. Questionnaires were applied to investigate the research problem. It was administered to 1000 managing directors of the biggest (according to the amount of business) Portuguese enterprises. Results suggest that Portuguese enterprises had a positive evolution between 2005 and 2007, and that, in lower maturity stages, the constraints are more significant.

Abstract
Due to data-driven application nature and its increasing complexity, developing its user interface can be a repetitive and time-consuming activity. Consequently, developers tend to focus more on the user interface aspects and less on business related code. In this paper, we're presenting an alternative approach to graphical user interface development for data-driven applications, that allows developers to refocus on the source code and concentrate their efforts on application core logic. The key concept behind our approach is the generation of concrete graphical user interface from a source code based model, which includes the original source code metadata and non-intrusive declarative language extensions that describes the user inter-face structure. Concrete user interface implementation will be delegated to specialized software packages, developed by external entities, that provides complete graphical user interfaces services to the application. When applying our approach, we're expecting faster graphical user interface development.

Abstract
With the recent expansion of services available in the Web, the Internet is becoming more and more a network of services, at a global scale. These services cover the majority of business areas, such as: bank account management, trip reservation, hotel bookings, information search portals, social networks, etc. A related subarea is the georreferencing of objects and people. The appearance of services like Google Earth and Virtual Earth has created enormous Web based service creation opportunities, allowing the interconnection of the digital and real worlds. In this work we present a project intended for locating the physical places associated with a person, based on his email address. This project implements a search portal that associates a user to an email and a set of user defined locations.
