Of course, different business data corresponds to different source data, for example, for expert extraction in the process of purchasing the project, the source data is a set of all relevant experts.
S103: configuring an extraction executor according to the service data;
the step aims at realizing the configuration of the extraction executor according to the related information configuration in the service data. The extraction executor is an execution main body for executing the data extraction task, and the extraction executor performs data extraction on the source data to obtain the required target data. Likewise, different service data corresponds to different types of extraction actuators, and different types of extraction actuators may also be configured differently, for example, when data extraction needs to be implemented by different data extraction algorithms, then the extraction actuators need to be configured with different data extraction algorithms.
As a preferred embodiment, the extracting actuator configured according to the service data may include: determining a business rule according to the business data; and configuring a decimation algorithm according to the business rule, and decimating the factor jammer and the link filter.

S104: and carrying out data extraction on the source data by using an extraction executor to obtain target data.
The step aims at realizing data extraction and obtaining target data, wherein the target data is data information which is needed to be obtained through data extraction. Specifically, after the configuration of the extraction executor is completed, the extraction executor completely corresponds to the current data extraction task and is used for executing the current data extraction task, so that the extraction executor performs data extraction on the source data obtained by loading, and the target data can be obtained. It should be noted that the number of the target data is not unique, that is, in the process of data extraction, there may be more than one data to be extracted, but this is determined based on the current data extraction task requirement, and the implementation of the present technical solution is not affected, which is not limited by the present application.

The preferred embodiment aims at realizing the determination of target data through man-machine interaction, namely determining whether the target data can be output as final extraction data or not through a target object corresponding to the target data. Specifically, after determining the target data, a confirmation request can be sent to a target object corresponding to the target data to request the target object to confirm, if confirmation information fed back by the target object is received, the target data is indicated to be feasible data, and then the target data is output; if the confirmation information fed back by the target object is not received, the target data is not feasible, and the data extraction needs to be carried out again until feasible new target data is obtained. For example, for the extraction of the expert in the process of purchasing the project, after the target expert is extracted and obtained, a confirmation request needs to be sent to the target expert to obtain the confirmation of the target expert, and the relevant information of the target expert can be output.
As a preferred embodiment, the data extraction method may further include: and sending the target data to display equipment for visual display.
The preferred embodiment aims to realize visual display of target data, namely after the data extraction is completed to obtain the target data, the target data can be sent to corresponding display equipment for visual display, so that a user can more conveniently and intuitively know the execution result of the current data extraction task.
