Distributed data access and management with OGSA-DAI (1/2) (90 mins)
Mike Jackson

This session provides a comprehensive overview of a powerful solution for distributed data access, management and integration - OGSA-DAI - and how it can be used to solve data-related problems in both enterprise and research contexts. An overview of OGSA-DAI is given as well as the latest work on increasing OGSA-DAI's power via distributed query processing and SQL view definition. It describes the relationship of OGSA-DAI to OGF's work on data access and integration standards - WS-DAI - and how such specifications provide a way of exposing OGSA-DAI's functionality in a more usable format and lends itself to inter-operability and integration with other service-oriented technologies.

Target audience: software developers, technical leaders

OGSA-DAI is OMII-UK's Grid data access and integration middleware product. Participants will learn about the problem space where OGSA-DAI sits as well as:

- How it can be used to achieve common data access and integration scenarios.
- How it offers a powerful solution for data access and integration scenarios by combining services with an underlying workflow engine.
- How OGSA-DAI can be used to develop well-defined services for data manipulation, with reference to WS-DAI.

By the end of the session, participants will have a good understanding of key features of OGSA-DAI, the problems it is designed to solve, and see how to reap the benefits of deploying in their projects. Examples of both research and business applications will be used.
