A sensor, a time alignment apparatus, a time processing method, and a time alignment method are provided. The sensor begins to sense at least one sensed data at a first local time instant. The sensor transmits a response message at a second local time instant. The response message carries the at least one sensed data, the first local time instant, and the second local time instant. The time alignment apparatus receives the response message at a first global time instant. The time alignment apparatus calculates a second global time instant that the at least one sensed data being sensed according to a required transmission time between the time alignment apparatus and the sensing apparatus, a clock skew rate between the time alignment apparatus and the sensing apparatus, the first global time instant, the first local time instant, and the second local time instant.

Sensing apparatus, time alignment apparatus, time processing method, and time alignment method

A candidate key retrieving apparatus, a candidate key retrieving method and a tangible machine-readable medium thereof are provided. The candidate key retrieving apparatus comprises a storage unit and a microprocessor. The storage unit is configured to store a table recording a data amount of the table, a plurality of attributes, and a data distinct amount and a data type of each attribute. The microprocessor is configured to generate a candidate key according to the data amount, the distinct amounts and the data types.
