Abstract: A first computer system designates a search condition, requesting a second computer system to retrieve records that satisfy the search condition from a database. The second computer system retrieves all records that satisfy the search condition from the database, sending the contents thereof to the first computer system. The first computer system executes preset data manipulations on a memory to the database object, which corresponds to contents of the retrieved records, recording the contents of the data manipulations into the memory as a log by a record. The first computer system stores the contents of the database object and the log after the data manipulation into a massage, sending it to the second computer system when all preset data manipulations to the database object are completed. The second computer system accesses the database according to the log in the received massage to reflect the database object to the database.

Abstract: In a computer network, a front end processor (FEP) is connected to at least one processor via a network node and connected to a plurality of terminals via a switched network. The FEP has means for executing a communications processing application, a means for creating and managing connections between the front end processor and the network nodes upon request from a terminal, a means for referring to the network nodes to be used by the particular terminal by a logic name, rather than its physical address, when communicating, and a means for changing and/or updating the logical name to be used by the terminal when addressing the network node. The FEP has an internal connection means holding a node management table indicating connection relationships between the terminals and network nodes so that no access to a name server is required. This reduces network traffic and facilitates flexibility in setting connections.
