20 Cambridge Oxford Glasgow Cardiff Southampton London Belfast Daresbury Lab RAL Hinxton OGSA-DAI Partners EPCC & NeSC Newcastle IBM USA IBM Hurseley Oracle Manchester EPCC & NeSC IBM UK IBM USA Manchester e-SC Newcastle e-SC Oracle $5 million, 18 months, started 1 st February 2002

21 OGSA-DAI Scope Definition and development of generic Grid data services which provide access to and integration of data held in databases, and the management of data within a distributed environment. Database A stored, structured collection of data Accessed using an API that takes account of the structure of the data stored Includes Relational and object databases XML repositories Adequately described collections of files

22 Databases in the Grid Computational Complexity Data Complexity

23 Scope of Database Services Discovery of Data by Content Query and Update Statements Metadata Management & Evolution Transactions (Flavours of) Distributed queries and updates Specialised types Encapsulated (safe) Function application Notification (driven by triggers, etc.)

24 OGSA-DAI Objectives Produce specifications for generic data services based on a common design framework consistent with Open Grid Service Architecture Design specifications as basis of standards recommendations via Database Access and Integration Services Working Group to the Global Grid Forum Deliver Grid data services software in future releases of the Globus Toolkit (GT3 December 2002) Refine identified requirements evaluate design options develop demonstrators transfer skills to the Grid community Develop reference implementations of generic data services Ensure that the Grid model and OGSA standards address fully the needs of data access and integration Ensure Grid data services meet the levels of service required performance, scalability, resilience, availability, and manageability evolution and distribution large user populations and large data volumes

39 OGSA-DAI & OGSA <((-:} Description, e.g. portType Works Well Adding only one portType / GDS(F) | DSR Expect to make extensive use of Data Service Elements Special to DBs: Static & Dynamic Component Management Notification Grid-FTP Accounting Security: Authentication, Authorisation & Privacy Reliable invocation …

40 OGSA-DAI & OGSA <))-:} Lifetime Issues Conditions for termination Controlled clean-up opportunity Scope of State Evolution Notification Issues Registering & using same notification system For DBs, e.g. triggers do we have to construct a dummy Service Data Element? Type System Issues Standards needed for wide range of types Service Definition Issues How to create / obtain standard definitions for common services

41 OGSA-DAI Summary On Schedule & Going Well Expect Contributions via GGF5 Expect Contributions to GT3 Releases Early Days Testing Architectural Design Using OGSA Working with Early Adopter Pilot Projects AstroGrid & MyGrid Planned release of prototypes Influence OGSA-DAI direction Via DAIS-WG
