TAILIEUCHUNG - Báo cáo " Specifying Object-Oriented Design Patterns using OWL "

Design patterns provide good solutions for problems occurred in the design stage. Using design patterns in the software development processes helps improve productivity and quality of software products. Pattern Oriented Analysis and Design Process has four steps related to patterns, namely the acquaintance with design patterns in the pattern library, the retrieval of the pattern candidate, the selection of suitable patterns and the application of selected patterns. | VNU Journal of Science Natural Sciences and Technology 26 2010 89-94 Specifying Object-Oriented Design Patterns using OWL Vu Dieu Huong1 Nguyen Van Vy1 Le Viet Ha2 1 College of Technology VNU 144 Xuan Thuy Hanoi Vietnam 2Information Technology Institute VNU 144 Xuan Thuy Hanoi Vietnam Received 20 July 2009 Abstract. Design patterns provide good solutions for problems occurred in the design stage. Using design patterns in the software development processes helps improve productivity and quality of software products. Pattern Oriented Analysis and Design Process has four steps related to patterns namely the acquaintance with design patterns in the pattern library the retrieval of the pattern candidate the selection of suitable patterns and the application of selected patterns. It is necessary to have a method to specify patterns in a machine understandable form to automate the above four steps. Some works have tried to specify the structural aspects of design patterns by ontology. We add the specification of the behavior aspects into design pattern ontology so that this ontology can be used to automate steps in the Pattern Oriented Analysis and Design Process. Keywords design pattern OWL Ontology. 1. Introduction Pattern Oriented Analysis and Design Process POAD is a systematic process that promotes pattern-based development 1 . POAD consists of four important steps acquaint with design patterns in the reusable asset library retrieve of the pattern candidates select suitable patterns and use the selected patterns. Design patterns are usually described in the unstructured documents. A pattern document includes many sections such as name of pattern intent motivation applicability applicability context of patterns structure implementation and consequence 2 . Corresponding author.
