DATA MANAGEMENT SYSTEM FOR EXCHANGE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To obtain the data management system for an exchange and its method that avoids deterioration in a memory operating efficiency and decrease of a processing rate and that can revise efficiently a system capacity of the exchange in operation. SOLUTION: A block assignment management object 1a divides data areas of each memory into pluralities of blocks each having a same fixed size, manages the data areas by block unit, assigns an optional number of optional blocks to each data and sets flexibly a data capacity by increasing/decreasing the assigned numbers so as to efficiently change a system capacity of the exchange in operation.
