Viewing Metadata Extensions

Nonrelational source and target definitions have metadata extensions that displays additional information from the data map used to create the definition. With VSAM and sequential definitions, the File Name extension field can be modified.

You can override the data map name and schema name in the session properties.

The following table describes the extensions on the Metadata Extensions tab for a nonrelational definition:

Access Method	Method that you specified in the data map to access the source database: A = Adabas D = IMS DL1 E = VSAM ESDS I = IDMS K = VSAM KSDS O = IMS ODBA N = VSAM RRDS S = sequential (SEQ) W = DB2 unload file (DB2UNLD) X = Datacom Z = DB2 data map
comments	Any comments.
File Name	Name of the data set (sequential or VSAM only).
Hierarchy Structure	For source and target definitions for which you selected Use Sequence Fields , the XML that describes the hierarchy structure of the data. Click the arrow in the Value column to display the XML. For more information, see Hierarchy Structure.
