Use Case - Create a Custom ODA Data Source

Revision as of 17:14, 25 October 2006 by Lchan.actuate.com (Talk | contribs)

Purpose

The Open Data Access (ODA) component is an open and flexible data access framework that provides an uniform way for any consumer application to access data from heterogeneous data sources. Any data provider who wants to be consumed by an ODA consumer application such as BIRT, may plug in a custom data source driver that implements the ODA runtime and design-time extension points.

Extension Points Involved

  • ODA Runtime extension point:
    • org.eclipse.datatools.connectivity.oda.dataSource
  • ODA Design-time extension points:
    • org.eclipse.datatools.connectivity.oda.design.ui.dataSource
    • org.eclipse.datatools.connectivity.connectionProfile
    • org.eclipse.ui.propertyPages

Java API Interfaces/Classes

  • ODA runtime data access
    • org.eclipse.datatools.connectivity.oda package (Java interfaces for runtime data access)
    • org.eclipse.datatools.connectivity.oda.manifest package (utility classes to access the content of own plug-in manifest)
  • ODA Design-time API for defining a data source and data set design
    • org.eclipse.datatools.connectivity.oda.design package
    • org.eclipse.datatools.connectivity.oda.design.ui.designsession.DesignSessionUtil class (utility class to manipulate ODA Design API objects during an ODA design session)
  • ODA Designer API for contributing provider-specific design UI pages
    • org.eclipse.datatools.connectivity.oda.design.ui.wizards package
    • org.eclipse.datatools.connectivity.oda.design.ui.pages.impl package (default implementation to define a data source design)
    • org.eclipse.datatools.connectivity.oda.design.ui.manifest package (utility classes to access the content of own plugin manifest)

Exemplary Clients

  • CSV Flat-file data source -
    • org.eclipse.datatools.connectivity.oda.flatfile and org.eclipse.datatools.connectivity.oda.flatfile.ui plug-ins
  • XML data source -
    • org.eclipse.datatools.enablement.oda.xml and org.eclipse.datatools.enablement.oda.xml.ui plug-ins
  • BIRT JDBC data source -
    • org.eclipse.birt.report.data.oda.jdbc and org.eclipse.birt.report.data.oda.jdbc.ui plug-ins
