This paper presents a high-level overview of the design and implementation of the core components of the OGSA-DAI project. It describes the design decisions made, the project’s interaction with the Data Access and Integration Working Group of the Global Grid Forum and provides an overview of implementation characteristics. Further details of the(More)
UNLABELLED TAMBIS (Transparent Access to Multiple Bioinformatics Information Sources) is an application that allows biologists to ask rich and complex questions over a range of bioinformatics resources. It is based on a model of the knowledge of the concepts and their relationships in molecular biology and bioinformatics. AVAILABILITY TAMBIS is available(More)
Active database systems support mechanisms that enable them to respond automatically to events that are taking place either inside or outside the database system itself. Considerable effort has been directed towards improving understanding of such systems in recent years, and many different proposals have been made and applications suggested. This high(More)
Modeling user interfaces is a well-established discipline in its own right. For example, modeling techniques can describe interaction objects, 5 tasks, 6 and lower-level dialogs in user interfaces. 7 For more than 10 years, researchers have tried to build comprehensive interface development environments that integrate models for describing a user(More)
Rules have been proposed for providing active behaviour in DBMS. Previous attempts to add rules to Object Oriented DBs have often resulted in a dichotomy between rules and other kind of objects. Bere a uniform approach is presented, in which rules are described and handled in the same way as any other object in the system, without any additional mechanisms(More)
The UK e-Science Programme is a £250M, 5 year initiative which has funded over 100 projects. These application-led projects are under-pinned by an emerging set of core middleware services that allow the coordinated, collaborative use of distributed resources. This set of middleware services runs on top of the research network and beneath the applications we(More)
Conducting bioinformatic analyses involves biologists in expressing requests over a range of highly heterogeneous information sources and software tools. Such activities are laborious, and require detailed knowledge of the data structures and call interfaces of the different sources. The TAMBIS (Transparent Access to Multiple Bioinformatics Information(More)
Distributed query processing (DQP) has been widely used in data intensive applications where data of relevance to users is stored in multiple locations. This paper argues: (i) that DQP can be important in the Grid, as a means of providing high-level, declarative languages for integrating data access and analysis; and (ii) that the Grid provides resource(More)
