Paper Abstract:
|
Much work is under way within the grid community on both technical and organizational issues associated with the
design and implementation of services to provide seamless and flexible access to data from multiple autonomous,
distributed data sources through a virtualized interface. To serve the purpose, the Open Grid Services Architecture Data
Access and Integration (OGSA-DAI) standard has emerged. However, several technical obstacles arise in the design and
implementation of such services. In this paper, we are particularly interested with a notable obstacle, namely how clients
within a grid environment can be kept automatically informed of the latest and relevant changes (insert and update) about
data committed in a single or multiple autonomous distributed databases and/or data sources. It is our view that keeping
all interested clients informed of changes of their interest committed will increase homogeneity and consistency
across their environment. With this in mind, we go on to describe in detail a relevant scenario on how to extend current
functionality offered by OGSA-DAI to keep interested clients informed automatically about relevant up-to-date data. |
