    The ability to rapidly find potential business partners as well as rapidly set up a collaborative business process is desirable in the face of market turbulence. Collaborative business processes are increasingly dependent on the integration of business information systems. Traditional linking of business processes has a large ad hoc character. Implementing situational enterprise services in an appropriate way will deliver the business more flexibility, adaptability and agility. Service-oriented architectures (SOA) are rapidly becoming the dominant computing paradigm. It is now being embraced by organizations everywhere as the key to business agility. Web 2.0 technologies such as AJAX on the other hand provide good user interactions for successful service discovery, selection, adaptation, invocation and service construction. They also balance automatic integration of services and human interactions, disconnecting content from presentation in the delivery of the service. Another Web technology, such as semantic Web, makes automatic service discovery, mediation and composition possible. Integrating SOA, Web 2.0 Technologies and Semantic Web into a service-oriented virtual enterprise connects business processes in a much more horizontal fashion. To be able run these services consistently across the enterprise, an enterprise infrastructure that provides enterprise architecture and security foundation is necessary. The world is constantly changing. So does the business environment. An agile enterprise needs to be able to quickly and cost-effectively change how it does business and who it does business with. Knowing, adapting to diffident situations is an important aspect of today’s business environment. The changes in an operating environment can happen implicitly and explicitly. The changes can be caused by different factors in the application domain. Changes can also happen for the purpose of organizing information in a better way. Changes can be further made according to the users' needs such as incorporating additional functionalities. Handling and managing diffident situations of service-oriented enterprises are important aspects of business environment. In the chapter, we will investigate how to apply new Web technologies to develop, deploy and executing enterprise services

    Abmash: Mashing Up Legacy Web Applications by Automated Imitation of Human Actions

    Get PDF
    Many business web-based applications do not offer applications programming interfaces (APIs) to enable other applications to access their data and functions in a programmatic manner. This makes their composition difficult (for instance to synchronize data between two applications). To address this challenge, this paper presents Abmash, an approach to facilitate the integration of such legacy web applications by automatically imitating human interactions with them. By automatically interacting with the graphical user interface (GUI) of web applications, the system supports all forms of integrations including bi-directional interactions and is able to interact with AJAX-based applications. Furthermore, the integration programs are easy to write since they deal with end-user, visual user-interface elements. The integration code is simple enough to be called a "mashup".Comment: Software: Practice and Experience (2013)

    Veebimaastikul suurt populaarsust kogunud tavatarbijatele suunatud vidinapõhised veebi-rakendused on loonud soodsa pinnase üldotstarbeliste mashup’ite loomise raamistike ning tööriistade tekkeks. Need tööriistad on eelkõige suunatud tava-Interneti kasutajatele, et luua lihtsaid mashup-tüüpi rakendusi. Samal ajal oleks vidinapõhistest veebirakendustest kasu ka ärirakendustena. Peamiseks takistuseks ärirakenduste loomisel veebipõhiste raken-dustena on keerulisest äriloogikast tulenevad keerukad nõuded ning protsessid. Antud magistritöö uurib, kuidas teostada veebividinatel põhinevate mashup-tüüpi ärirakenduste arendamist nii, et säiluks mashup’ite loomisega seotud peamised eelised, lihtsus ja kiirus. Käesolev magistritöö pakub välja laienduse olemasolevale mashup-tüüpi raamistikule, et toetada mashup’i dekompositsiooni rollipõhisteks vaadeteks. Selleks jagatakse mashup väiksemateks vidinate komplektideks, tagades igale kasutajarollile komplekt just temale vajaminevatest vidinatest. Kuigi igal kasutajarollil võib olla erinev vaade kogu ärirakendusest, tagab käesolevas magistritöös pakutud lahendus suhtluse nende erinevate vaadete vahel. See on vajalik tagamaks mashup’i eksemplari ühtsust kõikide mashup’i vaadete vahel, olenemata sellest, millistest vidinatest antud kasutaja vaade koosneb. Lisaks pakub käesolev magistritöö välja lahenduse toetamaks mitut eksemplari samast vidinapõhisest ärirakendusest ning toetamaks ärirakenduse oleku salvestamist ning taastamist. Kuna ärirakendused on suunatud lahendamaks kasutajate igapäevaseid ülesandeid, on vajalik, et kasutaja saaks valida olemasolevate mashup’i eksemplaride hulgast või alustada uut eksemplari. Lisaks on vajalik, et kasutaja saaks igal ajahetkel rakenduse kasutamise lõpetada selliselt, et hiljem rakenduse kasutamist jätkates oleks tagatud sama rakenduse olek, millest kasutamine katkestati. Väljapakutud lahenduse toimimist testitakse näidisrakendusega, mis realiseerib krediidihalduse protsessi.Recent hype on consumer web mashups has resulted in many general-purpose mashup frameworks and tools. These tools aim at simplifying the creation of mashups targeted to mainstream Internet users. At the same time, mashups are also used for solving specific business-related tasks. Such mashups are called enterprise mashups and more sophisticated frameworks and tools have been developed to support their creation. However, similarly to traditional web application development tools, the complexity of these frameworks is hindering the main benefits associated with mashup development – agility and simplicity. This thesis aims at extending a general-purpose mashup framework to support develop-ment of enterprise mashups while still preserving the simplicity and agility of develop-ment. More specifically, this thesis describes a solution for role-based decomposition of mashups for multi-instance executions with state sharing, preservation and restoration. In this thesis, a general-purpose mashup framework is extended with the concept of roles to support multi-user interaction and decomposing complex enterprise mashups with rich interactions into role-based views. In the context of this thesis, a view is defined as a subset of widgets a mashup is made of. Hence, through views an effective mechanism is provided for decomposing enterprise mashups to mashups as simple as general-purpose mashups. Additionally, this thesis proposes a generic solution for multi-instance mashup executions. In this thesis, each workflow instance is associated with an instance of a mashup. Since situational applications target at solving users day-to-day tasks, it is necessary to support multiple instances of a mashup. Furthermore, support for multiple mashup instances leverages users’ ability to participate in multiple workflow instances and to initialize new ones. Such mashup instances are in this thesis also referred to as mashup sessions. Finally, a solution is proposed for supporting mashup state sharing, preservation and restoration. Sharing states with other users is the key mechanism for facilitating interaction and collaboration between multiple users. State preservation and restoration are needed to allow a user to stop using the mashup and to resume to the same state at a later time. The proposed solution is also validated through a proof of concept application

    Developing front-end Web 2.0 technologies to access services, content and things in the future Internet

    The future Internet is expected to be composed of a mesh of interoperable web services accessible from all over the web. This approach has not yet caught on since global user?service interaction is still an open issue. This paper states one vision with regard to next-generation front-end Web 2.0 technology that will enable integrated access to services, contents and things in the future Internet. In this paper, we illustrate how front-ends that wrap traditional services and resources can be tailored to the needs of end users, converting end users into prosumers (creators and consumers of service-based applications). To do this, we propose an architecture that end users without programming skills can use to create front-ends, consult catalogues of resources tailored to their needs, easily integrate and coordinate front-ends and create composite applications to orchestrate services in their back-end. The paper includes a case study illustrating that current user-centred web development tools are at a very early stage of evolution. We provide statistical data on how the proposed architecture improves these tools. This paper is based on research conducted by the Service Front End (SFE) Open Alliance initiative

    The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-04244-2_8Web mashups are a new generation of applications based on the composition of ready-to-use, heterogeneous components. They are gaining momentum thanks to their lightweight composition approach, which represents a new opportunity for companies to leverage on past investments in SOA, Web services, and public APIs. Although several studies are emerging in order to address mashup development, no systematic mapping studies have been reported on how quality issues are being addressed. This paper reports a systematic mapping study on which and how the quality of Web mashups has been addressed and how the product quality-aware approaches have been defined and validated. The aim of this study is to provide a background in which to appropriately develop future research activities. A total of 38 research papers have been included from an initial set of 187 papers. Our results provided some findings regarding how the most relevant product quality characteristics have been addressed in different artifacts and stages of the development process. They have also been useful to detect some research gaps, such as the need of more controlled experiments and more quality-aware mashup development proposals for other characteristics which being important for the Web domain have been neglected such as Usability and ReliabilityThis work is funded by the MULTIPLE project (TIN2009-13838), the Senescyt program (scholarships 2011), and the Erasmus Mundus Programme of the European Commission under the Transatlantic Partnership for Excellence in Engineering - TEE Project.Cedillo Orellana, IP.; Fernández Martínez, A.; Insfrán Pelozo, CE.; Abrahao Gonzales, SM.

    Enterprise Mashups: A New Approach for Business Solutions

    Get PDF
    A mashup is a Web application that integrates content from different providers in order to create a new service which is not offered by the content provider. The development of this kind of applications involves activities such as accessing heterogeneous sources, combining data from different data sources and building graphical interfaces. This factor limits non-experienced computer users to develop these applications. However, nowadays there are enterpriseoriented tools that allow non-experienced user for building mashups in order to respond business needs in an easy and rapid way. Due to this, the enterprise mashup approach has been widely adopted by a large number of enterprises. This paper presents an overview of the enterprise mashup approach, as well as a review of four enterprise-oriented tools which provide a set of features that allows non-expertise users developing mashups into an enterprise. Finally, we present the challenges to be addressed by enterprise-oriented mashup tools in order to provide an easier and faster way of developing mashups
