  • 7. Tasks Involved in Warehouse Builder Administration – Administer the repository – Perform metadata backup – Manage repository and recovery and target users – Manage metadata – Manage security changes privileges OWB – Diagnose errors – Troubleshoot repository common issues Sources Target – Maintain target warehouse schema objects – Tune performance of ETL processes (optional)
  • 8. Steps for Setting Up the Warehouse Builder Environment 1. Verify the installation requirements. 2. Determine the environment configuration scenarios. 3. Prepare the server infrastructure (OS, Database). 4. Install optional components. 5. Install Warehouse Builder. 6. Create the Warehouse Builder repository.

  • 12. Design Center Menus Save Toolbar Project Explorer Connection Explorer Project Explorer: Holds all project organized metadata (also known as your design). Connection Explorer: Holds all information about physical locations and how these are managed in control centers Global Explorer: Holds all objects that are shared among users across the repository. It holds pre-built content, and you can create your own content for sharing across projects. Global Explorer
