Abstract

With respect to one order information piece in security transaction, processing of reception, transaction condition confirmation, transaction settlement and result transmission is executed serially. A transaction system is configured so as to divide a transaction including a plurality of transaction requests into predetermined units and execute resultant processing units in parallel. When such division is conducted, the sequential property is ensured. For example, the progress situation of processing is stored in a database every processing and every step. Issues, terminals, markets and servers are included as predetermined units.

Claims10

Dependent claims

A transaction system connected to a plurality of transaction terminals which respectively belong to some of a plurality of groups and which transmit transaction requests, the transaction system conducting security transaction processing according to the transaction requests, the transaction system comprising:

an acceptor provided for each of the groups, the acceptor comprising means for accepting a transaction request containing a transaction issue, and means for determining whether an accepted transaction request has been received normally and means responsive to normal reception for transmitting a reception result to a transaction terminal that has transmitted the transaction request and storing the transaction request in a requirement database;
a plurality of transaction processors respectively associated with security transaction issues, each of the transaction processors comprising means for extracting a transaction request corresponding to a transaction issue of itself from the requirement database, and means for registering the extracted transaction request in the requirement database as a transaction acceptable state;
and
a plurality of contract processors respectively corresponding to security transaction issues, each of the contract processors comprising means for accepting a second transaction request according to a transaction request registered as the transaction acceptable state, with respect to a transaction request according to a transaction issue of itself included in transaction requests registered in the requirement database, means for making a decision whether contract processing is possible in the transaction request and the second transaction request, and means for registering a transaction request that reflects a result of the contract in the requirement database,
wherein the transaction system is capable of executing a plurality of security transactions in parallel.

2 more elements

A transaction system connected to a plurality of transaction terminals which respectively belong to some of a plurality of groups and which transmit transaction requests, the transaction system comprising a plurality of processors, the transaction system conducting security transaction processing according to the transaction requests,

wherein
the processors comprise first processors for issuing a processing request which is issued to execute at least a part of the security transaction processing and which loses validity sometimes after issuance, and second processors for executing processing according to the processing request,
the first processor
issues the processing request, and
stores requirement information for executing processing corresponding to the processing request and to be executed in response to the processing request, in a requirement database, and
the second processor
determines whether there is an issued processing request,
(1) if there is the processing request, the second processor retrieves corresponding requirement information from the requirement database and executes corresponding processing,
(2) unless there is the processing request, the second processor conducts retrieval in the requirement database, and conducts retrieval for unprocessed requirement information for processing to be executed by itself,
if there is unprocessed requirement information, the second processor issues request information corresponding to presence of unprocessed requirement information to itself, and
upon receiving the request information, the second processor acquires corresponding requirement information from the requirement database and executes pertinent processing.
