Abstract: Disclosed is an electric starter with a manual turning function. A main shaft, a drive gear mechanism, a shift fork, an electromagnetic relay guide rod and a first return spring are arranged in a housing of the electric starter. A gear shifting mechanism comprises a force receiving component which extends out of the housing of the electric starter and serves as an external force applying point so as to promote the electromagnetic relay guide rod to move rightwards, a normally closed switch for cutting off a power supply of the electric starter when the force receiving component moves to an extreme position, a positioning component for locking the force receiving component when the force receiving component moves to the extreme position, and a first return component which enables the force receiving component to automatically returns to an original state when the force receiving component is unlocked.

Abstract: The data ETL (Extraction-Transformation-Loading) dispatching method of the present invention is applied to a real-time data ETL system, wherein a main ETL dispatching engine executes tasks according to preset sequence. In the execution, some key information are memorized by the main ETL dispatching engine, such as lscycle (latest successful data cycle), curcycle (current processing data cycle), and endcycle (processing end data cycle), etc., and are transferred to called programs. After the execution of the called programs, the main ETL dispatching engine records and keeps the updated dispatching information. In the data re-extraction, the data ETL dispatching method is adopted for the automatic re-extraction of some tasks and some cycles therein.

Abstract: As for the memory dispatching method applied to real-time data ETL system, the main ETL dispatching program executes one task according to preset sequence. In the execution, some key information are memorized by dispatching engine, such as lscycle (latest successful data cycle), curcycle (current processing data cycle), and endcycle (processing end data cycle), etc., are transferred to the called program. After the execution of the called program, the dispatching engine records and keeps the updated dispatching information; in the data re-extraction, memory dispatching method is adopted for the automatic re-extraction of some tasks and some cycles therein.
