A Method of Handling Metamodel Based on XML Database for SW Visulization

Software visualization shows to extract the architecture from source code. With software visualization, we can improve the software quality due to software modularization and also reconfiguration. To do this, we compose of parser, data analyzer, database management system, and visualizer like a tool-chain for realizing the software visualization. In this tool-chain, we develop the parser named xCodeParser that generate the OMG's Abstract Syntax Tree Metamodel (ASTM) for various language such as C, C++ or Java. In this paper, we propose the metamodel based XML databases to save the ASTM files into the repository. The proposed database is able to handle the data which organized metamodel based on XML database. Improving quality through realizing this visualization helps easily to develop high quality software, to increase reusability, and to reduce maintenance cost.
