System records

The Oracle Endeca Server data domain uses system records to store configuration information.

You can configure the following system records:

Property Description Records (PDRs), used to define the format and behavior of standard attributes and managed attributes.
Dimension Description Records (DDRs), used to define managed attributes and thus, among other characteristics, enable the creation of hierarchical standard attribute values.
The Global Configuration Record (GCR), used to control various aspects of the global configuration.

To avoid naming collisions with customer-created records and attributes, the keys for system records use reserved prefixes, such as mdex-property.
