Database
The name of the current database and, when the current database is a physical database, the names of the logically related databases.
Segment
The names of the segments in the listed databases.
Related Database
The name of the database containing the related segment (see below).
Related Segment
For physical databases, the name of the logical parent of the segment. This field is blank if the segment is not a logical child.

For logical databases, the names of the physical segments that comprise the logical segment. For concatenated segments, two segment names are listed. A 'K' appearing after the segment indicates that the KEY operand was specified on the SOURCE= parameter of the SEGM statement. The absence of a 'K' indicates that the DATA operand was specified.

Key Start
The starting position of the segment's key field.
Key Length
The length of the segment's key field.
IDR Rules
The insert, delete and replace rules for the segment. FIRST, HERE and LAST indicate the insert position rules.
Relationship
Whether the segment is a real logical child or a virtual logical child.
REAL LOG CHILD
real logical child segment
VIRT LOG CHILD
virtual logical child segment
