For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0060] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0063] S110: Obtain basic data;

[0064] S120: Landing the basic data on a central server and / or application system to obtain a central timestamp of the basic data;

[0065] Optionally, the S120 includes:

[0066] Landing the basic data once on a central server, obtaining a unique identifier that is mapped one-to-one with the basic data landed once, and recording a central timestamp of the basic data landed once;

[0067] The basic data that was landed once is landed in the application system for a second time, and a mapping relationship between the basic data that was landed twice and the unique identifier is established.

[0068] In the specific implementation of this specification, basic data can be obtained by uploading or generated by users. The basic data is first landed on the central server once, and a uuid is assigned to establish a mapping relationship with the basic data of the first landing, and a central timestamp is added. Subsequently, the basic data is pushed to the application system for a second landing, and a mapping relationship between the uuid and the basic data of the second landing is established. Through the mapping relationship between the uuid and the basic data of the first landing and the basic data of the second landing, the limitation of the unique data source is eliminated.

[0069] S130: Determine whether the data source time of the landed basic data is updated compared to the central timestamp;

[0075] In the specific implementation of this specification, if the data source time of the basic data is compared with the central timestamp and there is an update, the updated basic data is re-landed on the central server in real time and the central timestamp is updated. Subsequently, based on the unique identifier, the basic data that is matched to the second landing is pushed to the corresponding application system.

[0080] The updated basic data after forced conversion is updated to the application system.

[0081] In the specific implementation of this specification, field information includes but is not limited to field type, field length, and field format. To determine whether the field information of the updated basic data meets the field rules, the field information of the secondary landing basic data can be referenced. If the two are inconsistent, the updated basic information is forcibly converted based on the field rules.

[0083] When the data source time of the secondary landing basic data is updated compared to the central timestamp, the basic data of the primary landing is matched based on the unique identifier, the updated basic data is updated to the central server, and the central timestamp is updated based on the data source time;

[0084] Based on the unique identifier matching the basic data of the secondary landing, the updated basic data is updated to the application system.

[0085] In the specific implementation of this specification, after the secondary landing basic data is updated, the central server obtains the updated secondary landing basic data from the application system based on the unique identifier and implements it. Subsequently, the central server pushes the updated basic data to the remaining application systems for update.

[0086] The present invention adopts an innovative method of secondary landing, breaking the limitation of a single data source; through a central server, it does not invade the application system and does not require a large number of changes to the application system; it establishes a mapping relationship between the unique identification code and the basic data, improves matching efficiency, and simplifies the problem of data synchronization.
