Migration of form based legacy systems towards service-oriented computing is a challenging task, requiring the adaptation of the legacy interface to the interaction paradigm of Web services. In this paper, a wrapping methodology is proposed to make interactive functionalities of legacy systems accessible as Web services. The wrapper that is used for interacting with the legacy system acts as an interpreter...
Migration of form based legacy systems towards service-oriented computing is a challenging task, requiring the adaptation of the legacy interface to the interaction paradigm of Web services. In this paper a flexible wrapper supporting a process for making accessible functionalities of legacy systems as Web services is presented
The increasing importance of Web-based applications and the use of new Internet protocols for building service oriented applications point to new directions in the construction of this kind of systems. New challenges and problems arise when moving to a service oriented approach. Many times, the implementation of real scenarios using Web services involves the use of context information according to...
Web applications design methodologies hold the promise of engineering high-quality and long-lived Web systems and rich Internet applications. However, many such methodologies focus solely on green-field development, and do not properly address the situation of leveraging the value locked in legacy systems. This paper proposes a holistic approach to redesigning legacy applications for the Web using...
In this paper, we present ADAMS (ADvanced Artefact Management System), a Web-based system that integrates project management and artefact management features, as well as context-awareness and artefact traceability features. In particular, we focus on two features of the tool, namely hierarchical versioning and traceability support
Legacy programs, i. e. programs which have been developed with an outdated technology make-up for the vast majority of programs in many user application environments. It is these programs which actually run the information systems of the business world. Moving to a new technology such as service oriented architecture is impossible without taking these programs along. This contribution presents a tool...
Database reverse engineering in general has only been used to recover the conceptual schema employed during its construction. To the best of our knowledge, none of this work has made use of that static structure to perform a deep analysis to infer functionality, or in other words, services over data that could be offered via Web services. Our work goes beyond the discovery of functionality, generating...
