Abstract: A method of data loading for large information warehouses includes performing checkpointing concurrently with data loading into an information warehouse, the checkpointing ensuring consistency among multiple tables; and recovering from a failure in the data loading using the checkpointing. A method is also disclosed for performing versioning concurrently with data loading into an information warehouse. The versioning method enables processing undo and redo operations of the data loading between a later version and a previous version. Data load failure recovery is performed without starting a data load from the beginning but rather from a latest checkpoint for data loading at an information warehouse level using a checkpoint process characterized by a state transition diagram having a multiplicity of states; and tracking state transitions among the states using a system state table.

Abstract: Techniques for reducing a number of computations in a data storage process are provided. One or more computational elements are identified in the data storage process. An ordered structure of one or more nodes is generated using the one or more computational elements. Each of the one or more nodes represents one or more computational elements. Further, a weight is assigned to each of the one or more nodes. An ordered structure of one or more reusable nodes is generated by deleting one or more nodes in accordance with the assigned weights. The ordered structure of one or more reusable nodes is utilized to reduce the number of computations in the data storage process. The data storage process converts data from a first format into a second format, and stores the data in the second format on a computer readable medium for data analysis purposes.

Wherein these detected signals should be filtered before being used, and the best filter is the low-pass filter to cut out the high frequency components, and the cut-off frequency of the low-pass filter are determined by the motor running voltage U and PWM signal width when the motor is running at no load, finally determine if the motor is working properly by means of the motor running parameters stored in the database in advance, that is to determine if the detected value is identical with the one predicted from the database.
