Example 8. DBX and DBY exist, DBZ is to be added

In example 8, DBY must be reorganized to add the logical child pointers in the segment C prefix. The procedure for this example and all conditions and considerations are exactly the same as the procedures for example 6.

Example 8 is shown in the following figure.

Figure 1. DBX and DBY exist, DBZ is to be added
DBX has SEG A, SEG B. DBY has SEG C, child SEG X. DBZ has SEG D, child SEG E. Logical relationships between SEG B and SEG C, between SEG A and SEG X. SEG C to be logical parent and child of SEG E.
