Abstract
In an information management system, individual entity information items related to one another are assigned unique identifiers. A smaller number of pointers are used to define high, low, front and rear-rank links among the entity information items. In an entity management table are placed records having a pointer to an entity information item and an identifier of the entity information item. In a structure management table are placed records representing types of the entity information items and having pointers to high, low, front and rear-rank records. There is further provided an identifier management table that relates the types of the entity information items to the identifiers. Use of these tables permits data retrieval in four directions of upward, downward, forward and rearward.
