Selector
An IDoc header element whose value determines which of several possible mappings will be used for an
IDoc. For example, the value of the element SNDPOR in the IDoc header specifies which of several
possible mappings to use for an ORDERS05 IDoc.
Subscription
A request, by an application, to be notified when a specified change or type of change occurs in the Data
Store. Support for subscriptions is a feature of NonStop SQL/MX. The component that stores and acts on
subscriptions is called the Subscription Module.
Subscription Module
The component of the Director that stores and acts on subscriptions. When the Data Store changes in a
way that meets the condition of a subscription, the Subscription Module reads the relevant data from the
Data Store and constructs an outgoing message, which it posts to a JMS queue.
Subscription Registration Interface
An application used to register subscriptions with the Director. A subscription specifies the condition (in
an SQL SELECT statement) on which a subscribing application wishes to receive notification, and the
format of the message to be delivered to the subscribing application. The interface also provides ways to
browse and delete existing subscriptions.

A document definition that replaces an existing base document definition without requiring WLS to be
shut down. The substitute document definition has a unique class name that distinguishes it from the
definition it replaces.

A business process that links functions such as customer asset management, manufacturing, and finance
within an enterprise or across enterprises, so that an enterprise, its suppliers, it distributors, and its
customers are operationally integrated.
SystemKey
A metadata option used to generate a unique 64-bit number and assign it to column in a table. This
enrichment is usually used to generate a unique key for a record.
System key affinity
A partitioning strategy in which an incoming child record is assigned a partition ID consistent with a
previously assigned unique key occurring in the record. This is the strategy to use to locate a child and a
parent in the same partition when the records in question have the same relationship across document
types.
Upsert
A document insertion mode in which existing records pertaining to the document are updated with new
information. This mode contrasts with Delsert, in which existing records are deleted and the new
document inserted in its entirety.
