Parsing method of JSON and protocol buffer at the Android platform

다국어 초록 (Multilingual Abstract)

As people who use the Internet through the smart phone increased, they started to complain about service speed. To fulfill such user requirement, several kinds of data-formats emerged such as XML. And to improve data transfer rate among servers which can satisfy users’ request and the device which the users use, another data-format called JSON was developed. Recently, Google developed a new data-format called Protocol Buffer. Our purpose was to offer users several kinds of knowledge about data-formats especially parsing method of three data-format and, through the experiments comparing between XML, JSON and Protocol Buffer, show that our parsing method was right or wrong and which one is the fastest data-format. To do this, we developed streaming server, parsing server and Android Application. By using these developments, we did experiments that compared three data-formats and observed that our development was useful when developers use our method and Protocol Buffer, above all other data-formats, is the fastest. Also at this paper, we explained the architecture of the new data-format and the method how can convert data-format and its’ example.
