摘要： PURPOSE:To attain the output of the buying/selling support information, the risk control information, and a simulation function onto the screen of a single work station by connecting a bond buying/selling support system to a bond control system via a network. CONSTITUTION:The market and price information inputted in real time from a circuit 1 is received by a processor 2 and then transmitted to the work stations WS 4 and 5 of the dealers via a network 3. At the WS 4 and 5, the necessary data are acquired from the data bases 7 and 8 storing the positions, i.e., the bond transaction balance of each dealer so as to support the decision of the buying/selling actions and the recognition of a risk state. The bond buying/selling results are also inputted through the WS 4 and 5, and the information on a position data base is changed. A bond control system B consists of a processor 6 and a bond control data base 9. The processor 6 is connected to a WS of a dealing support system A via a circuit 10. Then, the data control, the gains control and the simulation are carried out in the system B.

摘要： PURPOSE:To secure connection of a terminal equipment with no consciousness of the limit of communication control hardware, by registering only the information on connection to the terminal equipment desiring transmission immediately before a communication program starts transmission of the connection information to be registered to the communication hardware. CONSTITUTION:A user program 1 designates the number of a terminal equipment to which the connection is desired and a connection request command is produced. Thus the value showing the connection request is registered 6 to a communication control table 4-1 corresponding to said terminal equipment. A communication control program 2 decides in a fixed cycle whether or not the connection requests are given to the table 4-1. When a connection request is detected, the terminal unit connection information 16-1 corresponding to the requested terminal equipment is extracted and registered 9 to a variable part 22 of a connection information area included in a communication control hardware 3. In such a case, the registering quantity is always equal to a single terminal device. If a connection request 6 is simultaneously given to plural terminal equipment, the request 6 is processed according to the priority levels of those terminal equipments defined previously.

摘要： PROBLEM TO BE SOLVED: To provide an efficient data updating method by which a client/server system can be expanded flexibly by minimizing the transmitted amount of table updating data which are transmitted to a business data base in large quantities. SOLUTION: The user program 33 of a client computer 30 acquires the processing request made from a user by operating the computer 30 and registers the data inputted by the user, the terminal number identifying the registered user, and a business management serial number specifying a business request in trigger processing interface data bases 16-18. The user programs 160-180 of a client server computer 10 acquire the data registered by the client computer 30 and executes table updating processing on decided plural business data based.
