- "Both ODI and OWB have a similar (I am being very simplistic here) three-component design of: a metadata repository, a development environment where the developer defines the processes and data flows and a runtime component that executes the code and flows."
- Speicherung des Repositories:
- OWB: Repository ist vorinstalliert in einer Oracle-DB
- das ODI Repository wird mit Hilfe des Oracle Fusion Middleware’s Repository Creation Utility in einer unterstützten DB angelegt (nicht notwendig Oracle)
- Standard-Operationen:
- "with OWB the key parts of the IDE are those for the development of MAPPINGS and (optionally) the design of process flows to orchestrate mappings."
- "In the ODI world think INTERFACES for mappings and PACKAGES for process flows. This is simplistic though as ODI also has PROCEDURES (code developed in one of the ODI supported languages) and LOAD PLANS (multiple packages orchestrated to execute in serial or parallel)"
- Umsetzung der Operationen:
- OWB mappings require the developer to include all of the components needed to facilitate the mapping – we connect source columns to target columns through a logic flow of joiners, filters, expressions, aggregates and a whole palette of other activities. Typically, this would generate a single, but large, SQL statement with much use of in-line views." (immer PL/SQL)
- "ODI interfaces are simply about connecting source columns to target columns in a logical relationship (we also create expressions, joins and filters here) and allowing the physical implementation to be supplied by a knowledge module." (kann auch einfach SQL sein)

OWB und ODI
Peter Scott von Rittman Mead Consulting verspricht eine Artikelserie, in der er die Unterschiede zwischen Oracle Warehouse Builder (OWB) und Oracle Data Integrator (ODI) erläutern will und liefert zunächst eine Zusammenfassung der konzeptionellen Gemeinsamkeiten und Unterschiede:
