Abstract: A method and apparatus for transmitting mass data includes receiving data transmission request information from a client, for data transmission by a transceiver of a Web Application Server (WAS), determining a size of data requested by the client from a database storing the data based on the data transmission request information by a data checker of the WAS, sequentially reading data of a predetermined size out of the whole data to be transmitted according to the size of the whole data and storing the read data in a memory of the WAS by a data extractor of the WAS, sequentially converting the read data to a predetermined data format by a data converter of the WAS, sequentially transmitting the converted data to the client by a transceiver of the WAS, and deleting the completely transmitted data from the memory of the WAS by a data deleter of the WAS.

Abstract: A rendering processing apparatus and method using multiprocessing are disclosed. The rendering processing method includes dividing an application execution window into frames and generating a rendering processing command for rendering processing of an image on a frame basis by a pre-rendering manager, generating a rendering image for a frame according to the generated rendering processing command by a rendering manager, and storing the generated rendering image in a memory. A task for generating a rendering processing command is divided into at least one task, a task for generating a rendering image is divided into at least one task, and the divided tasks can be processed simultaneously in a plurality of threads.
