Code Complexity on Before and After Applying Design Pattern through SW Visualization

Software is actually depended on his/her coding maturity of each developer. Software is inevitably used in all fields due to ICT convergence, which is increasing on the issue of code quality. His/her developer avoids to show source codes to other persons, and also repeats to modify them, which finally makes spaghetti codes. Therefore, it will be possible to increase bug occurrence, and also fall below legibility and understanding of the code. Its code quality is depended on the maturity of a developer. To protect this problem, we apply SW visualization with GOF design pattern to make good design structure. Design pattern is a verified solution to provide with object oriented design. Code complexity is essentially referred to software quality, which has low complexity to easily understand, and has low possible to occur errors. In this paper, the SW Visualization method is applied to compare the relationship between each code complexity Before and After applying design pattern to enhance the quality of codes.
