DAIT(DAI Two)
NeSC Review
18 March 2004
Description and Aims
Grid is about resource sharingData forms an important part of that vision
Data on Grids:May be geographically distributedStorage technology and formats are not homogeneousNeed to dynamically bind to data sources on demand
Grid enabled data resourcesDiscoverable through published metadataRobust against variations in standardsEasy to aggregate, federate and manage
Goals for DAIT
Keep the OGSA-DAI name for DAITAim to deliver application mechanisms that:
Meet the data requirements of Grid applications Reduce development cost of data centric Grid applications Provide consistent interfaces to data resources Functionality, performance, etc.
Acceptable and supportable by database providers Provide a standard framework that satisfies standard requirements Trustable, imposed demand is acceptable, etc.
A base for developing higher-level servicesDistributed query processing

Points to Note
Most projects seem to be biologicalFeedback from users largely positive
Need more
Hope to allow user contributionsNeed to establish a policy/framework for this
Engage more with User CommunityMeetings scheduled for later this year
OGSA-DAI users meeting at NeSC in April OGSA-DAI mini-workshop at AHM 2004 OGSA-DAI tutorials at various meetings/locations
Protecting Your Users
Very rapidly moving fieldTechnology changesStandard changesMiddleware changes
Need to ensure:Technology adopters investment in OGSA-DAI is protectedShielded from future change
Positives:Document interface helpfulClient toolkit
Tech Preview in R3.1
DAIT Roadmap
R3.1 Feb 2004 - Technical Preview part of R4User Group: inaugural meeting – April 7th 2004R4.0 April 2004
Performance & monitoringAdditional DBMSs supported (SQL Server, Postgres)DBMS management operations
archive, restore, bulk load
File accessClient librariesInstallation wizardUser support, courses, training material, performance report
DAIT Roadmap 2
R5 October 2004Alignment with DAIS Spec
Assuming specs settle post GGF11
Integration into Globus Toolkit WS-RF friendly
Basic Web Services friendly as well?
R6 April 2005R7 October 2005
Increased data integration toolsFunctionality driven by user group
