ODI Topology Coponent List of Objects

Topology Navigator

Topology Navigator is used to manage the data describing the information system's physical and logical architecture. Through Topology Navigator you can manage the topology of your information system, the technologies and their data types, the data servers linked to these technologies and the schemas they contain, the contexts, the language and the agents, as well as the repositories. The site, machine, and data server descriptions will enable Oracle Data Integrator to execute the same mappings in different environments.
This section contains these objects:

Physical Architecture

The physical architecture defines the different elements of the information system, as well as their characteristics taken into account by Oracle Data Integrator. Each type of database (Oracle, DB2, etc.), file format (XML, Flat File), or application software is represented in Oracle Data Integrator by a technology.

Contexts

Contexts bring together components of the physical architecture (the real Architecture) of the information system with components of the Oracle Data Integrator logical architecture (the Architecture on which the user works).
For example, contexts may correspond to different execution environments (Development, Test and Production) or different execution locations (Boston Site, New-York Site, and so forth.) where similar physical resource exist.

Logical Architecture

The logical architecture allows a user to identify as a single Logical Schema a group of similar physical schemas - that is containing data stores that are structurally identical - but located in different physical locations. Logical Schemas, like their physical counterpart, are attached to a technology.

Languages

Languages defines the languages and language elements available when editing expressions at design-time. Languages provided by default in Oracle Data Integrator do not require any user change.

Repositories (Master & Work Repositories)

The topology contains information about the Oracle Data Integrator repositories. Repository definition, configuration and installation is covered in the Installation and Upgrade Guide for Oracle Data Integrator.
