ERP 2.0, what for and how?

International audienceThe poor level of adoption of ERP systems is often considered as linked to a loss of social interactions between users of the ERP, together with the poor adaptability of these huge systems to local needs. Web 2.0 tools (including among others social networks, wikis, mashups and tags) aim at allowing a better interaction between a user and an Internet site, or between communities of users by means of a Web site. Using these tools in an industrial context appears now as a possible solution for addressing some of the problems of present information systems, and especially ERPs. Examples of such integration of Web 2.0 technologies in industrial practices are analysed and the empiricism with which these experiences are usually conducted is underlined. In order to address this problem, we suggest a step-by-step method allowing to identify on which business processes performed by an ERP the Web 2.0 tools could be of interest, and investigate how to integrate the two worlds. This approach is illustrated on the SAP product Business By Design, which new version includes a set of configurable Web 2.0 tools

Web-Wide Application Customization:The Case of Mashups

Application development of is commonly a balancing of interests, as the question of what should actually be implemented is answered differently by different stakeholders. This paper considers mashups, which are a way of allowing an application to grow beyond the capabilities of the original developers. First, it introduces several approaches to integrate mashups into the services, or Web pages, that they are based upon. These approaches commonly implement ways to determine which mashups are potentially relevant for display in a certain Web page context. One approach, ActiveTags, enables users to create reliable mashups based on tags, which effectively, leads to customized views of Web pages with tagged content. A scenario that demonstrates the potential benefits of this approach is presented. Second, a formalization of the approaches is presented which uses a relational analog to show their commonalities. The abstraction from implementation specifics opens the range of vision for fundamental capabilities and gives a clear picture of future work

Pro Web 2.0 Mashups: Remixing Data and Web Services

XXXIII, 603 p. ; 24 cmLibro ElectrónicoEn cub.: Remix the Web to create cutting-edge web applicationsHow many times have you seen a web site and said, “This would be exactly what I wanted— if only . . .” If only you could combine the statistics here with data from your company’s earnings projections. If only you could take the addresses for those restaurants and plot them on one map. How often have you entered the date of a concert into your calendar with a single click instead of retyping? How often do you wish that you could make all the different parts of your digital world—your e-mail, your word processor documents, your photos, your search results, your maps, your presentations—work together more seamlessly? After all, it’s all digital and malleable information—shouldn’t it all just fit together? In fact, below the surface, all the data, web sites, and applications you use could fit together. This book teaches you how to forge those latent connections—to make the Web your own—by remixing information to create your own mashups. A mashup, in the words of the Wikipedia, is a web site or web application “that seamlessly combines content from more than one source into an integrated experience.”1 Learning how to draw content from the Web together into new integrated interfaces and applications, whether for yourself or for other others, is the central concern of this book.¿Cuántas veces ha visto usted a un sitio web y le dijo: "Esto sería exactamente lo que quería- si sólo. . . "Si sólo pudiera combinar las estadísticas aquí con los datos de las ganancias de su empresa proyecciones. Si tan sólo pudiera tener las direcciones de los restaurantes y colócalas en una mapa. ¿Cuántas veces has entrado en la fecha de un concierto en su calendario con un solo clic en lugar de volver a escribir? ¿Con qué frecuencia desea que usted podría hacer todas las diferentes partes de su mundo digital, el correo electrónico, los documentos procesador de textos, fotos, resultados de la búsqueda, sus mapas, sus presentaciones, trabajar juntos con mayor perfección? Después de todo, todo es digital y maleable que la información shouldn't a sólo encajan entre sí? De hecho, debajo de la superficie, todos los datos, sitios web, y aplicaciones que utiliza podría encajar. Este libro te enseña a forjar esas conexiones latentes a hacer de la web su propio por información remezcla para crear su propia mashups. Un mashup, en palabras de la Wikipedia, es un sitio web o aplicación web "que combina a la perfección el contenido de más de una fuente en una experiencia integrada. "1 Aprender a dibujar el contenido de la Web junto a nuevos interfaces integradas y aplicaciones, ya sea para usted o para otros, es el centro de preocupación de este libro.The modern Web is awash with data and services just waiting to be used, but how do you make effective use of all this information? The answer lies in APIs (such as Google Maps, Flickr, and Amazon Web Services) and remixing, or mashups. "Pro Web 2.0 Mashups: Remixing Data and Web Services" teaches you everything you need to create useful, dynamic real-world applications using APIs, web services, Ajax, web standards, and server-side languages. All you need to make full use of this book is basic knowledge of HTML, CSS, and JavaScript, and at least one server-side language (such as PHP or ASP.NET). Highlights include the following: Looks at the overall shape of todays Web from a developers point of view--what are its main features, and what is available for us to use to develop applications? Contains real-world examples of creating mashups using all the major APIs. Contains examples written in multiple server-side languages. What you'll learn Understand how the constituent parts of the modern Web fit together--web standards, Ajax, APIs, libraries, tagging, blogs, wikis, and more. Create different types of mashup, for example mapping mashups, search functionality, calendars, RSS/Atom feeds, social bookmarking, online storage systems, open document formats, and more. Build Web 2.0 applications using HTML, CSS, JavaScript, Ajax, server-side languages, APIs, and libraries Who is this book for?

A UI-driven approach to facilitating effective development of rich and composite web applications

It is well-recognized that the development of user interfaces is one of the most time-consuming tasks in the overall application development process. At the same time, there is an increasing demand for rich and fluid user interfaces from web users. As a result, developers are facing increasing challenges in delivering web applications, especially those with rich UI requirements. In this thesis we present two solutions to facilitate the execution and rapid development of web applications with rich user interfaces. The first solution is a rich internet application (RIA) framework aimed at providing high usability and productivity to web applications, while the second solution is a UI integration framework that simplifies web application development by facilitating the composition of reusable UI components. The foundation of our RIA framework is an XML-based high-level protocol for communicating asynchronous events and incremental UI updates on the web. The protocol facilitates rich and highly interactive UI, while at the same time eliminates frequent and slow page refreshes and provides a more responsive user experience. Built on top of the protocol, a server-side runtime allows UI logic code to be executed on the server side, while a set of server-side event-driven API enables developers to implement sophisticated application-specific UI behavior. On the client side, a thin client renders UI and processes native events, but leaves application-specific logic to the server side. The thin client thus allows end users to enjoy a rich UI experience in a safe client environment, without executing any downloaded code. The proposed UI integration framework includes an abstract UI component model which allows UI components to be programmatically manipulated via events, operations, and properties, essentially exposing UI as services. To facilitate component interactions, the framework offers an event-based composition model, which allows integration logic to be specified in the form of event listeners. Composite applications are executed via a lightweight runtime middleware, which provides component adapters that allow the middleware to communicate with native UI components implemented in a variety of languages and platforms. Finally, a graphical development environment allows composite applications to be built in a drag-and-drop fashion

A case study in social media mashup concept validation

Sosiaalinen media korostaa käyttäjien välistä vuorovaikutusta ja käyttäjien luoman sisällön mahdollistamista ja jakamista. Sosiaaliseen mediaan kuuluvat myös sosiaaliset verkostot, jotka yhdistävät ihmisiä. Mashupit taas ovat palveluja, jotka yhdistävät tietoa eri lähteistä ja näyttävät tämän tiedon uudessa kontekstissa. Tässä työssä käsitellään sosiaalista verkostoa nimeltä AmiCarta. AmiCarta keskittyy paikkatiedon hyödyntämiseen sosiaalisessa verkostossa. Työn tarkoituksena on validoida palvelukonsepti käyttäjillä. Työssä analysoidaan validointiin käytettyjä metodeja sekä käyttäjätestien tuloksia. Käyttäjätestit koostuvat kukin kolmesta osasta. Käyttäjille annetaan prototyyppi tuotteen käyttöliittymästä, jonka he käyvät läpi. Prototyyppi on luotu paperiprototyypeillä ja toimii wizard-of-oz metodilla. Protoyypin tarkastelun jälkeen käyttäjiä haastatellaan puolistrukturoidulla haastattelulla ja esitetään kyselylomake. Käytetyt metodit tuottivat pääasiassa kvalitatiivista tietoa. Prototyypin käytöllä oli haittavaikutuksena se, että se tuotti pääasiassa tietoa olemassa olevista ominaisuuksista, eikä juurikaan auttanut uusien ominaisuuksien ideoinnissa. Kvalitatiiviset tulokset antoivat ideoita siitä, mihin suuntaan konseptia tulisi viedä. Kyselylomakkeen tuottamat kvantitaaviset tulokset taas olivat käytännöllisiä ominaisuuksien vertailussa. Tutkimuksen perusteella konseptin perusajatus muuttui karttapalvelusta, johon on lisätty erilaisia ominaisuuksia palveluun, joka perustuu kommunikaation helpottamiseen ja tukemiseen paikkatiedolla.In social media user-generated content and sharing are emphasized. As a subcategory for social media there are social networks that connect people. Mashups are applications that combine data from existing sources and display the data in a new context. This study considers the case of AmiCarta, a social network service that focuses on location information. The study focuses on validating the concept and evaluating the used methods for validation as well as the obtained results. The concept is validated with user tests. Each user test was conducted in three parts. In the first part, the user was demonstrated a mock-up prototype of the mobile user interface for the product that was created using paper prototyping and theprototype responds to the user in a wizard-of-oz implementation. The second phase consisted of a semi-structured interview and the third phase of a questionnaire. The methods of the study produced mainly qualitative information. As a drawback, the use of a mock-up prototype mainly generated information about the existing features of the concept. Qualitative results gave insight on how the concept could be further developed. The quantitative results of the questionnaire were useful in ranking the features. As a result of the study, the focus of the service was moved from a map application that has different features to an application that enables communication between users and supports this communication with the users' location information
