Repository
Objects
You create repository objects using the Repository Manager,
Designer, and Workflow Manager client tools. You can view the following objects
in the Navigator window of the Repository Manager:
- Source
definitions. Definitions
of database objects (tables, views, synonyms) or files that provide source
data.
- Target
definitions. Definitions
of database objects or files that contain the target data.
- Multi-dimensional
metadata. Target
definitions that are configured as cubes and dimensions.
- Mappings. A set of source and target
definitions along with transformations containing business logic that you
build into the transformation. These are the instructions that the
PowerCenter Server uses to transform and move data.
- Reusable
transformations. Transformations
that you can use in multiple mappings.
- Mapplets. A set of transformations
that you can use in multiple mappings.
- Sessions
and workflows. Sessions
and workflows store information about how and when the PowerCenter Server
moves data. A workflow is a set of instructions that describes how and
when to run tasks related to extracting, transforming, and loading data. A
session is a type of task that you can put in a workflow. Each session
corresponds to a single mapping.
Information is very good and informative
