The method includes: receiving a relationship data query request carrying a target device identifier sent by a query device; acquiring, based on the target device identifier, all relationship data corresponding to the target device from a relationship database; and returning, to the query device, all the relationship data corresponding to the target device. ## Claims ### Claim 1 A method for managing data in an Internet of Things, the method comprising: receiving a relationship data query request carrying a target device identifier sent by a query device; acquiring, based on the target device identifier, all relationship data corresponding to the target device from a relationship database; and returning, to the query device, all the relationship data corresponding to the target device. ### Claim 2 (depends on 1) The method according to claim 1, wherein the relationship data identifies a connection relationship, a hierarchical relationship, or a supply relationship between the target device and another device. ### Claim 3 (depends on 2) The method according to claim 2, wherein the target device is a physical object, and the other device is a physical object or a virtual object. ### Claim 4 (depends on 1) The method according to claim 1, wherein before acquiring, based on the target device identifier, all relationship data corresponding to the target device from a relationship database, the method further comprises: acquiring the relationship data between the target device and another device in the Internet of Things; and storing the relationship data between the target device and the other device into the relationship database in a tag mode. ### Claim 5 (depends on 4) The method according to claim 4, wherein the tag mode is represented by a key-value. ### Claim 6 (depends on 1) The method according to claim 1, wherein, if the target device is a physical object, the method further comprises: receiving data uploaded by the target device according to a preset attribute model; and storing the data of the target device into a service database. ### Claim 7 (depends on 6) The method according to claim 6, wherein the preset attribute model comprises at least one attribute defined in advance. ### Claim 8 (depends on 6) The method according to claim 6, wherein before storing the data of the target device into a service database, the method further comprises: detecting and determining data of a target attribute that needs to be stored according to a pre-configured data storage strategy; and the storing the data of the target device into a service database comprises: storing the data of the target attribute of the target device into the service database. ### Claim 9 (depends on 8) The method according to claim 8, wherein the pre-configured data storage strategy comprises: storing all the data of the reported target attribute; when the data of the target attribute received this time changes compared with the data stored last time, storing the data this time; or if the data received this time is greater than a preset threshold, storing the data received this time. ### Claim 10 A cloud server device, the device comprising: at least one processor; and a memory storing instructions, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising: receiving a relationship data query request carrying a target device identifier sent by a query device; acquiring, based on the target device identifier, all relationship data corresponding to the target device from a relationship database; and returning, to the query device, all the relationship data corresponding to the target device. ### Claim 11 (depends on 10) The device according to claim 10, wherein the relationship data identifies a connection relationship, a hierarchical relationship, or a supply relationship between the target device and another device. ### Claim 12 (depends on 11) The device according to claim 11, wherein the target device is a physical object, and the other device is a physical object or a virtual object. ### Claim 13 (depends on 10) The device according to claim 10, wherein before acquiring, based on the target device identifier, all relationship data corresponding to the target device from a relationship database, the operations further comprise: acquiring the relationship data between the target device and another device in the Internet of Things; and storing the relationship data between the target device and the other device into the relationship database in a tag mode. ### Claim 14 (depends on 13) The device according to claim 13, wherein the tag mode is represented by a key-value. ### Claim 15 (depends on 13) The device according to claim 13, wherein: if the target device is a physical object, the operations further comprise: receiving data uploaded by the target device according to a preset attribute model; and storing the data of the target device into a service database. ### Claim 16 (depends on 15) The device according to claim 15, wherein the preset attribute model comprises at least one attribute defined in advance. ### Claim 17 (depends on 15) The device according to claim 15, wherein before storing the data of the target device into a service database, the operations further comprise: detecting and determining data of a target attribute that needs to be stored according to a pre-configured data storage strategy; and the storing the data of the target device into a service database comprises: storing the data of the target attribute of the target device into the service database. ### Claim 18 (depends on 16) The device according to claim 16, wherein the pre-configured data storage strategy comprises: storing all the data of the reported target attribute; when the data of the target attribute received this time changes compared with the data stored last time, storing the data this time; or if the data received this time is greater than a preset threshold, storing the data received this time. ### Claim 19 A non-transitory computer readable medium, storing a computer program thereon, wherein the computer program, when executed by a processor, causes the processor to perform operations, the operations comprising: receiving a relationship data query request carrying a target device identifier sent by a query device; acquiring, based on the target device identifier, all relationship data corresponding to the target device from a relationship database; and returning, to the query device, all the relationship data corresponding to the target device.
