  • Transcript

    • 1. OWB Targets Targets (OWF/File/Schema), CIF, permissions, etc
    • 2. Targets are:
      • Physical Implementations of
        • Objects, Mappings, Data
        • Process Flows
        • File Load Mappings
      • Where the actual “work” occurs
      • “ Controlled” by RUNTIME REPOSITORY
    • 3. Targets Overview
    • 4. Target Types
      • Not Oracle terminology
        • Target Schema
        • Workflow Target
        • File System Target
    • 5. Target Types
    • 6. Corporate Information Factory
      • Overall Architecture
      • Put forth by Inmon/Imhoff
      • Three Tiers (really)
        • Stage
        • DW
        • Marts
    • 7.  
    • 8. Targets and Locations
      • Targets are PHYSICAL locations for OWB physical objects
      • Three layers instead of two (log/phys)
        • Logical Module (Design)
        • Logical Location (Design)
        • Physical Location (Runtime)
    • 9. DW_TGT2 DW_TGT1 OWB RT db10g.host.com DW_TGT2 DW_TGT1 OWB RT db9i.host.com DW_MOD_LOC2 -- Oracle 9i DW_MOD ORACLE MODULE DW_MOD_LOC1 -- Oracle 10g PHYSICAL LOCATION LOGICAL LOCATION LOGICAL MODULE RUNTIME DESIGN
    • 10. Connectors
      • Inter-module access
      • Built at DEPLOYMENT
      • Usually
        • Schema resolution
        • DBLink
    • 11. Connectors
    • 12. Schema Based / Security
      • Most target schemas are in the same database (3 tier split for logical reasons)
      • Most connectors are SCHEMA prefixes
      • Connectors are faster and more capable than DBLinks
      • Security must be setup outside of OWB for select/execute permissions for TGT to TGT interaction
    • 13. Questions
      • In addition to being just a ptr, what is the one piece of defined information in the LOGICAL location?
      • What registration information will be required for the following targets?
        • Target Schema
        • Workflow Target
        • File System Target
