Abstract:
A system and a method for data dispatch processing in a big data system are provided. The system includes a plurality of computing machines and a database cluster. The method includes disassembling a computing procedure into a plurality of processing elements. The method also includes identifying a database accessing point for accessing a target data node from one of the data nodes in the computing procedure. The method further includes configuring the processing elements to the computing machines according to the database accessing point, and transmitting a data tuple corresponding to the computing procedure according to the processing elements configured to the computing machines and a data transmitting cost between the computing machines. Accordingly, the method effectively improves system performance for transmitting the big data.
Abstract:
A method, an apparatus, and a system for generating and verifying a color barcode are provided. The method for verifying the color barcode is adapted to an electronic apparatus to execute verification with use of a color barcode certificate. In the method, direction information of a plurality of boundaries among a plurality of serially connected symbolic elements in the color barcode certificate is read to retrieve first authentication information of a first party. Each of the symbolic elements is one of at least two polygons, and colors of adjacent symbolic elements are different. Color information of the symbolic elements is then read to retrieve second authentication information of a second party. An identity of a holder of the color barcode certificate is verified according to the first authentication information and the second authentication information.
