and a database configured to store table information written by the data writing unit. ### Claim 2 (depends on 1) The system of claim 1, wherein the setting information and status information are specified as a primary key and a foreign key by including an identifier of a higher level entity. ### Claim 3 (depends on 2) The system of claim 2, wherein the data writing unit expresses the primary key and foreign key as an index. ### Claim 4 (depends on 1) The system of claim 1, wherein the table information includes a database which stores one or more of a gateway information table, an outdoor unit information table, an indoor unit information table, indoor/outdoor status tables, and a data table for various informational contents concerning the air conditioning system. ### Claim 5 (depends on 4) The system of claim 4, wherein the data writing unit specifies a primary key of the gateway information table as a foreign key for setting information and status information related to an outdoor unit of the multi-type air conditioning system. ### Claim 6 (depends on 5) The system of claim 5, wherein the data writing unit specifies a primary key of the setting information and status information related to the outdoor unit as a foreign key for setting information and status information related to an indoor unit of the multi-type air conditioning system. ### Claim 7 (depends on 6) The system of claim 6, wherein the data writing unit specifies a primary key of the setting information and status information related to the indoor unit as a foreign key for setting information and status information related to the indoor unit for monitoring and other informational contents of the multi-type air conditioning system. ### Claim 8 (depends on 1) The system of claim 1, wherein when data is to be added, the data writing unit abstracts an identifier from corresponding data, and by using the abstracted identifier, blocks data addition by a violation of a primary key restriction if the corresponding data is determined to be redundant data. ### Claim 9 (depends on 1) The system of claim 1, wherein when data is to be added, the data writing unit abstracts an identifier from corresponding data, and by using the abstracted identifier, blocks data addition by a violation of a foreign key restriction if the corresponding data is determined to be unreferenced data. ### Claim 10 (depends on 1) The system of claim 1, wherein when data is to be added, the data writing unit abstracts an identifier from corresponding data and adds the corresponding data if the corresponding data is determined by using the abstracted identifier to be referenced data, and not redundant data. ### Claim 11 (depends on 1) The system of claim 1, wherein when data is to be deleted, the data writing unit deletes corresponding data together with any data referring to the corresponding data. ### Claim 12 A data writing method for a multi-type air conditioning system wherein setting information and status information related to each of one or more multi-type air conditioner groups is contained in a table, comprising: writing the setting information and status information by tabulating a hierarchical relationship between devices of the multi-type air conditioning system through reference; and storing the written data in the table. ### Claim 13 (depends on 12) The data writing method of claim 12, wherein writing data comprises: writing the setting information and status information by specifying a primary key and an identifier of a higher level entity as a foreign key. ### Claim 14 (depends on 12) The data writing method of claim 12, wherein writing data comprises: writing setting information and status information related to an outdoor unit by specifying a primary key of a gateway table as a foreign key; writing setting information and status information related to an indoor unit by specifying a primary key of the setting information and status information related to the outdoor unit as a foreign key; and writing setting information and status information related to the indoor unit for monitoring and other informational contents of the multi-type air conditioning system by specifying a primary key of the setting information and status information related to the indoor unit as a foreign key. ### Claim 15 (depends on 12) The data writing method of claim 12, wherein when data is to be added, an identifier of corresponding data is abstracted, and if the corresponding data is determined by using the abstracted identifier to be redundant data, data addition is blocked by a violation of a primary key restriction. ### Claim 16 (depends on 12) The data writing method of claim 12, wherein when data is to be added, an identifier of corresponding data is abstracted, and if the corresponding data is determined by using the abstracted identifier to be unreferenced data, data addition is blocked by a violation of a foreign key restriction. ### Claim 17 (depends on 12) The data writing method of claim 12, wherein when data is to be added, an identifier of the corresponding data is abstracted, and if the corresponding data is determined by using the abstracted identifier to be referenced data, and not redundant data, the corresponding data is added. ### Claim 18 (depends on 12) The data writing method of claim 12, wherein when data is to be deleted, corresponding data is deleted together with any data referring to the corresponding data.
