PURPOSE:To grasp the entire situation of a subject in response to the change of the situation by processing only the monitor subject that has the changed data. CONSTITUTION:The quotation news information received from a quotation news system 7 of a stock exchange, etc., i.e., the data on plural types of subjects which vary irregularly are received by a CPU 8. The CPU 8 calculates various functions based on the received data and displays the results of these calculations on the terminal equipments 11 and 12. A table is prepared to show whether the data on various subjects are changed or not and whether the plural functions include the changed variable or not. When plural functions are calculated, only the functions that include the changed data as variables are calculated by reference to the contents of said table. As a result, the entire situation including the relevant subject can be monitored in real time. |
