Representation of Variability in Software Product Line Using Aspect- Oriented Programming Seung-hyun Heo, Eun Man Choi Dept.of Computer Engineering Dongguk University, Seoul, KOREA seknj@hanmail.net , emchoi@dgu.ac.kr Abstract Software development methodology has been being developed for the goal of improvement in productivity and reduction in time-to-market through the reuse of component asset, and software product line is designed for the effective management and use of the asset through the separation of commonality and variability. The existing methods that implement software product line interfere massively with the core asset, which require high cost in assembling level reducing the effectiveness. This paper introduces Aspect-Oriented Programming (AOP) as the method for the improvement of the assembling process in software product line. The method that assembles core asset and variabilities is described by grammar elements such as Join point, pointcut and advice without code-change. We analyze the requirements of the mini-system as an example adapting AOP and show its practicality by the implementation of Aspect-Oriented language, AspectJ 1. Introduction Reuse and version management are the key to achieve improvement of productivity. The reuse reduces time-to-market that is some of the most important and critical problem in software development. Software product line is a paradigm that combines them. If software product line is to be effective, requirements should be divided to commonalities and variabilities at the beginning of the development and then designed and implemented. Studies for software product line have been dealing with problems coming from design and development of product family to management tool for product line, representation and implementation of commonalities and variablities. Representation and implementation of variabilities are very important issue among them. The studies have been suggested that try to adapt AOP(Aspect-Oriented Programming) for requirements analysis of product line[1], and that is about design method by the extended UML[2,12]. In the implementation stage, there were research for method that can be used to implement variabilities[9]. But the real comparison was impossible because the standard was not clear for classified methods such as dynamic link, inheritance, conditional compile and AOP, and also it could not prove the availability of AOP at the code level. After that, there were attempts to manage component library asset and to develop products in a family[3,10] but it needs second language to create and manage the asset such as XML. Productivity of product line is affected quiet a bit by the efficiency of the assembly process of commonalities and variabilities. Therefore, development of product line costs to manage assets separately so that users are different from developer for components. Legacy methods that require understanding the assets for management and assembly reduce benefits are caused by the importation of product line.
