time estimate acquisition time
the taskName acquires task names used for designating various different types of acquisition tasks, and each acquisition task corresponds to different acquisition steps.
For pinpointing the scope of resource changes, incremental updates of data can be made based on these conditions.
Some other auxiliary information is also included in the model,
messageType event type, 1420 resource change message, 1424 resource change message reply message, 1424 message applies to a confirmation message that the party that needs to update the resource after the resource change does indeed complete the resource update action.
sessionId: the ID of the message originator, which may be used for message reply, is used to pair with the 1424 message, confirming that the sent 1424 message is a reply message to the previously sent 1420 message.

The data source information is a basic source of the data acquired this time, and may be a storage structure, a file, or location information determinable according to the attribute value, data information determinable according to the meeting of the setting condition, or resource information related to the data source.
The resource updating range is embodied in the definition of the resource data change model, the collected data source refers to the basic source of the data collected at this time, and may be a table of a database or a file, and is the maximum range of resource change, and the resource related to the data source can be determined through the value of the attribute. The acquisition time can be applied to updating time, only old data before the acquisition time is updated, the acquired data type can determine that only resource data of one or more data types are updated, and the data are only configured into the model to form a resource data updating notice.
Preferably, the attributes can be converted into SQL update conditions required by the data consumer, so that the update range of the data in the updated table and the table can be ensured, and the SQL update conditions can be directly configured into the resource data update notification.
Step S206: and the data consumer updates the resource data according to the resource data change notice.
