Data processing

An electronic device, applied to a data bus in an entity, wherein

• the electronic device comprises:
• a processor and a memory;
• the memory is configured to store instructions or a program;
• the processor is configured to execute the instructions or the program in the memory, to cause the electronic device to perform acts comprising:
• if a change of data occurs in a first service in a plurality of services of the entity, obtaining first update data of the first service, wherein the data bus monitors a database of the first service to detect the change of data;
• determining, from a predetermined correspondence, a target task corresponding to the first update data of the first service, the predetermined correspondence indicating a business processing policy of update data of a respective service on the data bus, and the target task comprising at least one second service in the plurality of services and a second operation performed by each of the at least one second service;
• and
• performing a corresponding second operation on each of the at least one second service, to cause data on the at least one second service on the entity to match the first update data of the first service, wherein the data bus triggers execution of the target task based on the predetermined correspondence.

A non-transitory computer-readable medium, applied to a data bus in an entity, wherein the non-transitory computer-readable medium stores instructions or a program which, when run on a processor, cause the processor to perform acts comprising:

• if a change of data occurs in a first service in a plurality of services of the entity, obtaining first update data of the first service, wherein the data bus monitors a database of the first service to detect the change of data;
• determining, from a predetermined correspondence, a target task corresponding to the first update data of the first service, the predetermined correspondence indicating a business processing policy of update data of a respective service on the data bus, and the target task comprising at least one second service in the plurality of services and a second operation performed by each of the at least one second service;
• and
• performing a corresponding second operation on each of the at least one second service, to cause data on the at least one second service on the entity to match the first update data of the first service, wherein the data bus triggers execution of the target task based on the predetermined correspondence.
