data domain

A logical collection of data and metadata managed by the Endeca Server. Through its interfaces, the Endeca Server allows for the data loading, configuration, and querying of a data domain. A data domain may impose order on subsets of its data through entities (known in Studio as views).

A data domain is the largest unit of data over which the Endeca Server allows queries to be expressed. It represents a discrete set of data and includes indexed data records and system records. (Applications wishing to correlate, join, or display data from multiple data domains must do so themselves.)

Each data domain runs one or more Dgraph processes. Each of the Dgraph processes runs on the Oracle Endeca Server node; depending on the number of Dgraph processes configured for the data domain, it can be hosted by more than one Endeca Server nodes.

To create a data domain hosted in the Oracle Endeca Server, you first create a data domain profile, using either the Endeca Server Web service interfaces or the endeca-cmd utility. You can then use this profile to create a new data domain. The Dgraph processes for this data domain will then be allocated and started on the available Endeca Server nodes.
