Abstract: A database management system (DBMS) generates a query execution plan including information representing one or more database (DB) operations necessary for executing a query and executes the query based on the query execution plan. In the execution of the query, the DBMS dynamically generates a task for executing a DB operation and executes the dynamically generated task. The DBMS executes a task in a plurality of threads executed by a processor core.

Abstract: Example implementations described herein are directed to the management of data received from an edge side when an update is issued to edge nodes from a core apparatus. When the edge nodes receive the update, the receipt of the update may not be uniform (e.g., due to latency, downtime, etc.), which results in an intermediate state where some edge nodes are updated and some edge nodes are not. Example implementations described herein address the processing of data from edge nodes when such an intermediate state occurs by conducting reprocessing of data when data is transmitted from edge nodes operating from an old configuration.

Abstract: Example implementations described herein estimate parameters for equipment that cannot be sensed directly, including determining if such equipment is running or stopping. Example implementations determine the standard throughput per equipment and product, based on history of equipment production data, extract previous and next equipment of robotic arms on the line by using physical topology information of robot arms and equipment, senses and determines throughput of associated robot arms and compares the robot arm throughput with the standard throughputs of the previous and next equipment, which help determine whether the previous/next equipment have stopped.

Abstract: Example implementations described herein involve defect analysis for images received from a camera system, which can involve applying a first model configured to determine regions of interest of the object from the images, applying a second model configured to identify localized areas of the object based on the regions of interest on the images; and applying a third model configured to identify defects in the localized ones of the images.
