President: Antoni Urpí Tubella 2. Vocal: Klaus Gerhard Langohr 3. Secretari: Carles Farré Tost QUALIFICACIÓ Qualificació numèrica: Qualificació descriptiva: Data: 4 5 ABSTRACT In the present thesis a possible next generation of e-commerce solutions with a platform-as-a-service model is presented and analyzed. This generation tries to fill the gap of missing developer-friendly alternatives to build systems with e-commerce components. Current offered solutions are mostly aimed for the comfortable use of designers and other non-technical roles, usually in the shape of out-of-the-box products. These solutions are usually limiting the ability of developers to integrate technologies or build innovative business models, thus sometimes forcing companies to invest in projects that have to be built practically from the start. This document describes the development of the first web-shop built with one of these solutions, SPHERE.IO, an e-commerce platform-as-a-service developed in Berlin by commercetools GmbH. During this process, questions are being answered about the suitability of e-commerce platforms to develop web-shops, a product most developers have to face when providing e-commerce solutions to companies. The web-shop has a dual purpose, as it will also serve as the first open-source template provided by the platform to help other developers build their own solutions. 6 ACKNOWLEDGMENTS I would especially like to thank Hajo for accepting being the director of my thesis and reading all these endless pages despite of having so much to do (really, how can you find the time!). Thanks for your support and always good advice to improve this project. I would also like to thank all the rest of the SPHERE.IO team for creating and raising such a great product, giving me the opportunity to work with them. From the ones that were: Aurélie, Jens, Roman, Ian, Lenni, Christian and Martin. (I loved the time we spent together, guys) To the ones that are: Nicole, Peter, Gregor, Dirk, Oleg, Nicola, Martin, Michael and Sven. I would like to thank my teacher Carles, who guided me through this project from the distance. Thank you especially for DSBW, which documentation I check constantly, not only for this project. Thanks to my roommate Sebastian, the most experienced online shopper I have ever met, whose advice was very convenient I must say. Thank you for helping me and have such loving cats that kept me well entertained during the long days locked in my room. Many thanks as well to those friends that helped me somehow to be where I am now. Particularly Hèctor and Pau, who help me the most. Thank you. And of course thousand thanks to the most important person in my life, my husband Héctor, whose constant care, support and help was so necessary during all my career life. I would not be here without you, you know that. Finally, I thank my parents, from whom I inherited the love for arts and business. Because they raised me to be a person capable of anything. And I chose to be a computer engineer. 7 INDEX Abstract ............................................................................................................................................. 6

  • Youbeq Management Platform >
    MSc in Informatics Engineering Internship Final Report YoubeQ Management Platform > Nuno Fauso Da Paixão Khan [email protected] DEI Supervisor: Fernando Barros iNovmapping Supervisor: André Santos Date: 2 July 2013 youbeQ Management Platform Abstract System integration and distributed systems are essential concepts in our current web development era. When relying on these aspects, one must acknowledge the importance of having a system that is mature, secure, reliable and scalable. The internship consists on the development of a management platform, called youbeQadmin, a web based application that integrates and manages youbeQ and Smarturbia, two existing applications developed by the company. These applications, already exist as independent web applications , that are now partially integrated in one single management platform. youbeqAdmin platform manages the youbeQ statistics and Smarturbia content (APPS). It enforces a distributed architecture while allowing the integration of these two modules/applications with the original web applications and with the possibility of easily integrating new modules into the platform in the future. The development of youbeQadmin required significant modifications to Smarturbia, mostly to allow a REST communication between them and to add new features like changing the vehicle color or applying area limits for the user to explore the world.

  • PHP Re-Factoring: HTML Templates
    PHP re-factoring: HTML templates Name of candidate: Dimitrios Kyritsis E-mail: [email protected] Date: September 2013 Host organization: Centrum Wiskunde & Informatica (CWI) URL: http://www.cwi.nl/ Address: Science Park 123, 1098 XG Amsterdam Contact persons: Mark Hills - [email protected] Jurgen J. Vinju - [email protected] 1 Abstract For every software developer the goal, when he creates software, is that the final result of his efforts meets its initial requirements. The software should operate as it was meant to, without any or at least without significant inconveniences. However, experienced developers have another goal, to write simple code. Their experience has taught them that the simpler the code is, the easier will be its maintenance. For web application developers the situation is the same. A way for them to write simpler web applications with easily maintainable code is to use template systems. Thereby, they can separate business logic from its presentation making their lives way easier, especially if they have to collaborate with web designers. Developers and designers will then have different fields of concern and the changes that they make will not affect each other's work. This thesis will describe our efforts to create an application which can automatically transform normal code into uses of template systems. In the beginning we will enumerate the factors that were taken into account for the creation of this application, along with a rationale for them. Subsequently, we will describe the steps and the decisions that were taken during the creation of our application. Finally, there will be a validation phase which will show if our application can really offer the advantages that was created for.

  • Overview 3. Joomla Advantages 4.Joomla Disadvantages
    1.Introduction to Joomla Learning Objective: Joomla has a web template system using a template processor. Its architecture is a front controller, routing all requests for non-static URIs via PHP which parses the URI and identifies the target page. This allows support for more human-readable permalinks. The controller manages both the frontend, public-facing view, and a backend (GUI-driven) administration interface. The administration interface (a) stores management and content information within a database, and (b) maintains a configuration file (configuration.php, usually located in the file system root of the Joomla installation). The configuration file provides the connection between the server, database and file system and facilitates migrating the website from one server to another. 2.Joomla - Overview Learning Objective:Joomla is an open source Content Management System (CMS), which is used to build websites and online applications. It is free and extendable which is separated into front-end and back-end templates (administrator). Joomla is developed using PHP, Object Oriented Programming, software design patterns and MySQL (used for storing the data). 3. Joomla Advantages Topics: • It is an open source platform and available for free. • By default, Joomla is compatible with all browsers. • Media files can be uploaded easily in the article editor tool. • It ensures the safety of data content and doesn't allow anyone to edit the data. • Since Joomla is so easy to use, as a web designer or developer, you can quickly build sites for your clients. With minimal instructions to the clients, clients can easily manage their sites on their own.
