Hi

A File record can be compared with a segment occurence in a IMS database. File record consist of some specified fields. Similarily a segment occurence has fields.
File record
01 File-Record
05 Name PIC X(10)
05 Address PIC X(20)
05 FILLER PIC X(50)

Segment
01 W200-SEGMENT-IO-AREA
03 FILLER PIC X(13)
03 W201-SEGMENT1-IO-AREA.
05 IM-SEGMENT1
10 IM-RSRVD-DATA PIC S9(4) COMP.
10 IM-KFLDIM PIC X(20)
10 IM-NAME PIC X(10)
10 IM-ADDRESS PIC X(20)

What i m trying to establish with these examples is that a file record is comparable to a segment occurence in a database.
A Database record is a collection of such segment occurences.
Starting from the root segment and traversing along the hierarchical structure of the IMS database from one segment to other until the last segment in the database constitutes one databse record.

Regards
Varun
