5results about How to "Reduce exceptions" patented technology

The application discloses a data reading and writing and erasing method and device, a computing device and a storage medium, and belongs to the technical field of data processing. The method comprises the following steps: after the smart device is powered on, data is read from the starting storage address of the state parameter storage area until the historical state parameter is read; in the process in which the smart device operates according to the historical state parameter, if a state parameter updating instruction is received, the state parameter is updated; in the case that it is detected that the smart device cannot normally operate, the current state parameter of the smart device is acquired; if the current state parameter is different from the historical state parameter and the remaining capacity of the state parameter storage area is smaller than the data capacity of the current state parameter, the state parameter stored in the target storage area of the state parameter storage area is erased, and the current state parameter is stored from the starting storage address of the target storage area. In this way, the frequency of data reading and writing and erasing is reduced, and the service life of the microprocessor for storing data in the smart device is prolonged.

The application discloses a laser cutting and workpiece coating method, device and computer readable storage medium. The method comprises the following steps: cutting a workpiece to be cut according to a first mode, to obtain an initial workpiece and a remaining workpiece to be cut; wherein a gap exists between the initial workpiece and the remaining workpiece to be cut; cutting an edge of the initial workpiece according to a second mode, to obtain an intermediate workpiece; and polishing the intermediate workpiece, to obtain a target workpiece. Through the above method, the attachment and residue of dust and other waste on the surface of the workpiece are effectively reduced.

This application provides a data processing method, apparatus, electronic device, and medium, relating to the field of data engineering technology. The method includes: determining a target field based on a first operation frequency and a second operation frequency of each field in a Data Definition Language (DDL) operation flow; calculating the path weights of a set of related paths between the target field and the first field to obtain a path weight set; calculating a comprehensive score for the first field based on the semantic similarity between the target field and the first field and the path weight set; and determining a replacement field based on the comprehensive score. The replacement field is used to replace the target field, and the replacement field includes the first field, a second field, and a third field, wherein the second field is a mixed value generated based on the first field, and the third field is a default value. This improves the flexibility and reliability of data processing and adapts to the ETL data flow requirements in scenarios with high-frequency field changes.
