User and media are in close coalition with each other in the 21st century's era of New-Media. The new users exposed to the New-Media environment have a complete understanding of the digital media environment, and are also taking on the role of an active identity in the formation of culture in new media. In the field of spatial design, creative spatial interfaces designed through various methods derived from the New-Media environment and technology that weren't even imaginable in the past ultimately came to exist in a mutual relationship with the user, the people. This study is in the same context as studies looking into the establishment of design in media art and digital media space in the New-Media environment. Media art is an outcome arising from the demand towards new art combined with the attempts towards accepting various media as a means for artistic expression. Media art seizes to being a mere part of art, but more. This study aims to look into the theoretical basis of New-Media and define the design process through the expressional characteristics and triggered thoughts thereof. Lastly, the results of the research will be put together to produce the final results. Such analysis process will be the basis of the creation of a new paradigm and spatial thought, and allow people to be concerned about the various changes in spatial formation.

In this paper, we propose a method which allows the SuperSQL query processor to share as much code as possible among various, generators, each of which is responsible for the output of a certain medium. SuperSQL is an enhanced query-processing system that converts database records into a variety of formats such as XML, HTML, PDF and etc. However, the existing SuperSQL media generator would require creation of a different processor for each medium, causing duplicated development cost. This research makes three main contributions: First, it analyzes the structures of various media, examining any possibility of integration based on their common structure. Second, it also facilitates the addition of a new output media generator by separating constructors and decorators from each medium. Last, it provides an integrated user interface to each media by method of the Media Abstraction Table Concept. We also show the performance and feasibility of our system using experimental results.
