3 Managing Versions
Oracle Data Relationship Management organizes sets of related data into versions. A version is a single, independent set of data that can represent a period of time or a business scenario. Data within each version is categorized into hierarchies, nodes, and properties. All data-related operations require selection of a version.
Separate versions are typically used for the following purposes:
-
To maintain historical copies of hierarchies, nodes, and properties for previous periods in time.
-
To create new data or model changes to existing data without affecting other users or processes.
-
To load data from different sources to be compared, rationalized, and blended.
