Set Mode
The mode of a set identifies how the relationship between participating record occurrences is represented within the database. The choices are:
- CHAIN- physically links each record in the set to the next record in the set. In other words, each record points to the next record in the set.
- INDEX- an index structure, or pointer array associates the owner of the set with each of its members. There is no physical linkage between adjacent member records.
