POS system, POS server, local terminal, method of dealing management, and recording medium

A POS server for managing deals of products at a plurality of stores comprising:

• a dealing database that stores information of said deals of products operated at a plurality of local terminals provided in said plurality of stores;
• a receiving device that receives a database operating instruction from each of a plurality of different control apparatuses, where each database operating instruction is the same, to update said dealing database about said deals of products from said local terminals every time said deals of products with at least one customer is completed;
• and
• a database updating device that updates said dealing database according to said received database operating instruction.

A local terminal, which is connected with a POS server having a dealing database for storing information of deals of products at a plurality of stores, comprising:

• a dealing management unit that processes dealing management of said deals of products operated at said stores;
• a generating unit that generates a database operating instruction to update said dealing database of said POS server with said dealing management;
• a copy unit that makes a copy of said database operating instruction for each of a first control apparatus, a second control apparatus and a backup device;
• an addressing unit that provides a same address respectively on each of the copies of said database operating instructions, where the same address is added for said first control apparatus, said second control apparatus and said backup device;
• a transmitting unit that transmits said plurality of database operating instructions including said addresses respectively toward said same address;
• and
• a network interface through which said plurality of database operating instructions are transmitted, the network interface including at least one communication network including the internet so that the local terminal communicates with the POS server through the internet.

A POS system, having a POS server with a dealing database for storing information of deals of products operated at a plurality of stores and local terminals at said plurality of stores being connected with said POS server, each of said local terminals comprising:

• a dealing management unit for processing dealing management of said deals of products operated at said stores;
• a generating unit that generates a database operating instruction to update said dealing database of said POS server with said dealing management;
• a copy unit that makes a copy of said database operating instruction;
• an addressing unit that provides a different address respectively on a plurality of said database operating instructions and for at least one control apparatus and a backup device;
• and
• a transmitting unit that transmits said plurality of database operating instructions being added said addresses toward the at least one control apparatus and the backup device, said POS server having a plurality of control apparatuses connecting with said plurality of local terminals provided at said plurality of stores, each of said plurality of control apparatuses comprising:
• a dealing database that stores information of said deals of products operated at said local terminals;
• a receiving device that receives a database operating instruction to update said dealing database about said deals of products;
• and
• a database updating device that updates said dealing database according to said received database operating instruction, whereby each of said receiving devices of said plurality of control apparatuses receives said database operating instruction transmitted to said control apparatus from said local terminal;
• a holding device that holds said received database operating instruction;
• a matching check device that checks matching of said database operating instruction held at each of said holding devices of said plurality of control apparatuses and said database operating instruction corresponding thereto;
• a recovering device that recovers said database operating instruction lost at the holding device of one of said control apparatuses by getting that the lost database operating instruction from any-one of said holding devices of said other control apparatuses that have said database operating instruction which is lost, wherein said database updating device updates said dealing database according to said recovered database operating instruction;
• and
• a network interface through which said plurality of database operating instructions are transmitted, the network interface having at least one communication network including the internet so that the local terminals communicate with each other and with one or more control apparatuses through the internet.

A method of dealing management for managing deals of products at a plurality of stores, comprising steps of:

• transmitting a database operating instruction stored in a holding device of a first control apparatus to a match checking device of a second control apparatus;
• transmitting another database operating instruction from a holding device of the second apparatus to the match checking device;
• checking the matching of the two database operating instructions to update a dealing database of the second control apparatus for storing information of said deals of products operated at local terminals provided in said stores about said operated deals of products from said local terminals every time said deals of products with at least one customer is completed;
• and
• updating said dealing database according to said received database operating instruction when the matching of the two database instructions is confirmed.

A method of dealing management for managing deals of products by using a POS server having a dealing database for storing information of said deals of products at a plurality of stores, comprising steps of:

• processing dealing management of said deals of products operated at said stores;
• generating a database operating instruction to update said dealing database of said POS server with said dealing management;
• making a copy of said database operating instruction for each of a first control apparatus, a second control apparatus and a backup device;
• adding a same address respectively on each of the copies of said database operating instructions, where the same address is added for said first control apparatus, said second control apparatus and said backup device;
• and
• transmitting said plurality of database operating instructions including said addresses respectively toward said same address.

A device for local terminals at stores connected with a POS server having a dealing database for storing information of deals of products at a plurality of stores, comprising:

• a dealing management module processing dealing management of said deals of products operated at said stores;
• a generating module generating a database operating instruction to update said dealing database of said POS server with said dealing management;
• a copy module making a copy of said database operating instruction for each of a first control apparatus, a second control apparatus and a backup device;
• an addressing module adding a same address respectively on each of the copies of said database operating instructions, where the same address is added for said first control apparatus, said second control apparatus and said backup device;
• and
• a transmitting module transmitting said plurality of database operating instructions including said addresses respectively toward said same address.
