IMS DB Question:
What are the two types of fields available in IMS DB?
Answer:
Key Fields - (PROCOPT=K)
► Used to sequence the database and can't be changed
► It’s the field within a segment, used to identify the occurrence of the segment
► used to maintain the IMS segments in ascending sequence.
Search Fields - (PROCOPT=G)
► Used to search for a segment, without the segment being sequenced on that field
► A segment need not have a key or search field.
Both types of fields can be used to search the database.
