From system requirements to source code: transitions in UML and RUP

There are many manuals explaining language specification among UML-related books. Only some of books mentioned concentrate on practical aspects of using the UML language in effective way using CASE tools and RUP. The current paper presents transitions from system requirements specification to structural source code, useful while developing an information system

Implementation diagrams in IT systems modeling

An inherent element of the documentation of IT system projects are the diagrams, which present the hardware and software infrastructure of the created systems. An example of such diagrams are implementation diagrams in the UML. There can be distinguished two types of implementation diagram, namely Component diagram and Deployment diagram. The aim of the present paper is to evaluate the possibilities of using the implementation diagrams for modeling of IT systems which use modern technology solutions. After discussing the role of implementation diagrams in IT systems modeling, the authors present also their functions and graphical conventions. Then, theoretical issues concerning diagrams and their practical uses have been examined and illustrated by the such examples of modern applications in the range of e-economy as: IT system of city traffic control, electronic warehouse management system and using mobile devices for purchase of e-tickets

RadioMarché: Distributed Voice- and Web-interfaced Market Information Systems under Rural Conditions

Despite its tremendous success, the World Wide Web is still inaccessible to 4.5 billion people - mainly in developing countries - who lack a proper internet infrastructure, a reliable power supply, and often the ability to read and write. Hence, alternative or complementary technologies are needed to make the Web accessible to all, given the limiting conditions. These technologies must serve a large audience, who then may start contributing to the Web by creating content and services. In this paper we propose RadioMarché, a voice- and web-based market information system aimed at stimulating agricultural trade in Sahel countries. To overcome interfacing and infrastructural issues, RadioMarché has a mobile-voice interface and is easy to deploy. Furthermore, we will show how data from regionally distributed instances of RadioMarché, can be aggregated and exposed using Linked Data approaches, so that new opportunities for product and service innovation in agriculture and other domains can be unleashed
