Loading logically related databases requires multiple steps that must be performed in a fixed sequence. In most cases, this involves multiple databases. The Makelist function can assist in creating the steps required to load a set of logically related databases.
The Load function performs a physical load of the segment data. The Load function does not process logical relationships. Logical children are connected to their logical parents by the PtrUpdate function. PtrUpdate also connects or establishes paired logical child relationships. A database which contains logical children segments cannot be accessed by an application until the PtrUpdate completes.
