Abstract
Electronic commerce is currently a world-wide phenomenon, with multiple impacts on the success and evolution of organizations of various business areas, due to its unique features that both challenge and revolutionize traditional entrepreneurial reasoning. However many enterprises have experienced difficulties with their e-commerce initiatives, either due to lack of information, or because of the innumerable difficulties found in the definition of an action plan. Recognizing the importance of a broad and deep understanding of the multiple aspects supporting and constraining e-commerce, a theoretical model that explains electronic commerce initiatives is proposed. The model was developed following a qualitative methodology known as Grounded Theory, whose purpose is to assist organizations in their e-commerce initiatives. The work led to the identification and description of factors that influence the adoption and exploitation of e-commerce in Portuguese organizations.

Abstract
In this paper we propose an architecture whose main goal is to improve productivity in user interface development for data-intensive applications. This objective is to be achieved by defining a high level model that describes the user interface structure. That model will be integrated in the source code through non-functional language extensions. Our final goal is allowing developers to define user interface model by adding language extensions to the source code and then acquiring an external software package to which they delegate the implementation of the concrete user interface.

Abstract
The information and communication technologies (ICT) have the potential to improve the quality of life of individual with functional particularities, potentiating their activity in society, as well supplying the conditions for a prolonged active life, counter acting the natural age related lost of faculties. As such, the software component - of ICT - is lacking a good and attentive construction to these functioning details which, often, are of difficult assessment. Adding to these constrains, the existing information is, not exclusively but especially, focused on Web contents. Attending to these matters, a checklist of proposals has been elaborated, and presented in this paper, that tries to cover these flaws, allowing for an evaluation of the accessibility of Integrated Development Environments (IDE), their capacity of generating accessible software - native software and not Web contents - and even the accessibility of the final product - the native software. Conceived through the reutilization and inspired on the general knowledge created by the Web Accessibility Initiative (WAI), the drafts of this checklist are easily understandable and applicable. With the objective of facilitating the work of information systems technician who may already have concerns regarding these topics, it further has the important potential of encouraging agents to initiate themselves into the cares that this are requires. © 2012 AISTI.

Abstract
The e-marketing, which arose as a variant of conventional marketing, demonstrates more and more his growing potential. Through the Internet and using new technologies, we can communicate with a growing number of potential customers around the world and create value in the company. With e-marketing, new internet based business techniques appeared, which have improved the business relationship with the customer, promotion and distribution of products and services and increase business income. The variety of existing e-marketing techniques allows companies a vast opportunity of choices depending on their needs. The research project presented in this article was aimed at conducting a survey to know which e-marketing techniques were most used by companies from the Autonomous Region of Madeira, and the results that arise from its use. © 2011 AISTI.

Abstract
Human pressure is pushing many of our natural resources to their limits in various regions of the world. Optimize their use is an urgent need. The management of agro-industry has been aware of that need, seeking to improve the productivity and reduce waste throughout the production process, as well by increasing the distribution efficiency of their products. Information and Communication Technologies (ICT) can support the control/management of the process inputs and outputs in various activities. This article attempts to describe a complete mushroom production chain. The information system developed by the agro-industry company studied allows to acquire, in real-time, the information about what is being produced (quantity and type of mushroom), which products are to be delivered to the different clients and which should be the planning for the next few days. © 2011 AISTI.

Abstract
The internet and technological advancements have revolutionized the way in which business and commerce is conducted nowadays. A lot has changed since the traditional over the counter form of trade to the electronic form of trade. The latter in which data is transferred electronically. E-businesses are beginning to examine the benefits of using Web 2.0, especially in the form of social networking sites, to collaborate with business partners and to communicate with consumers and potential employees. In order to create, possibly in the near future, a platform for selling services and typical Portuguese products, throughout this project various online companies' websites', which sell products and services, were analyzed. Other than analyze website characteristics we also tried to understand how these are sustained and how they interact with social networking services. © 2011 AISTI.
