Data Access and Integration

Web Services for querying and integrating structured data resourcesThe foundation framework for:

Building tailored DAI applicationsHigher-level services:

Replication: Data located in multiple locations Federation: Composition of multiple sources Provenance: How was data generated?

How OGSA-DAI works

OGSA-DAI compared to JDBC

Language independence at the client endPlatform independence

Do not have to worry about connection technology, drivers, etc

Can handle XML resourcesCan embed additional functionality at the service end

TransformationsThird party deliveryAvoiding unnecessary data movement

Provision of Metadata is powerfulUsefulness of the Registry for service discovery

Dynamic service binding process

Future DAI Services

Application Code

Activities are the drivers

Express a task to be performed by a GDSThree broad classes of activities:

StatementTransformationsDelivery

Extensible:Easy to add new functionalityDoes not require modification to the service interfaceExtension operate within the OGSA-DAI framework

Functionality:Implemented at the serviceWork where the data is (do not require to move data back)

OGSA-DAI Deck

Building Applications

Activities are grouped togetherPerform documentData can flow between activities

OptimisationAvoids multiple message exchanges

Can deliver to other GDSsPrerequisite for data integration

Base middleware for projects requiring data access

Some capability for data integration

BinX – accessing legacy binary data

The Problem:Many binary data filesApplications must “know”the data formatBinary data formats are machine-specific

BinX Library

The Solution:Write a “stand-aside” format description in XMLProvide a library to

Interpret the description Provide file access across different

machines

Build higher-level services

BinX file describes binary file structure
