We propose a linguistic mechanism for AspectJ-like languages that concisely associates aspect instances to object groups. The mechanism, which supports association aspects, extends the per-object aspects in AspectJ by allowing an aspect instance to be associated to a group of objects, and by providing a new pointcut primitive to specify aspect instances as(More)
This paper describes the design and implementation of association aspects, which are a linguistic mechanism for the AspectJ language that concisely associates aspect instances to object groups by extending the per-object aspects in AspectJ. This mechanism allows an aspect instance to be associated to a group of objects, and by providing a new pointcut(More)
One key to success for high quality enterprise information systems development is to validate the customers' requirements sufficiently at the early stage. Scenarios are an effective means to an end because they make it possible to represent various situations of system usage. Most scenarios are defined by using a natural language or such a formal language(More)
It has been widely acknowledged that ambiguous or incomplete customer requirements are a major reason for the failure of software development projects. A key example of this is the inconsistency between implementation image and specifications provided in the early stages of software development. To address this, we propose a method for automatic generation(More)
This paper proposes the stepwise automatic generation of a prototype system from the scenario based requirements analysis model based on UML. The system is a non-functional user interface prototype for Web applications. A scenarios is defined for every actor and for every normal, alternative and exceptional flow in a use case, so that it enriches the(More)
In recent years, it has been widely acknowledged that classes designed by utilizing PBL (Project-Based Learning) are effective in enhancing the problem-solving ability of university students. In PBL-based classes, students try to apply their knowledge to solve the problems by themselves; therefore, such classes are effective in improving problem-solving and(More)
The authors' goal is to establish a flexible programming support for evolving systems that will enable one to modify programs using less labor, while maintaining good quality during service life. EVA (evolution mechanism for flexible agent) was developed to allow a flexible programming support system to be constructed based on their programming method for(More)
Generally, end-users do so various kinds of operations on Web application systems that the developers often can not expect the effect on the system. However, it is very important that validity of user input is checked beforehand to avoid failures of service caused by unexpected user operation on Web application systems. We have proposed a method of(More)
Android malware is increasing and flooded with malware which disguise as popular applications and execute malicious attacks within the scope of permissions which was approved by users. Such malware can be prevented by confirming all risky permissions. However confirming permissions is not full preparation for preventing infection, because of defective(More)
Model Driven Development is a promising approach to develop high quality software systems. We have proposed a method of model-driven requirements analysis using Unified Modeling Language (UML). The main feature of our method is to automatically generate a Web user interface prototype from UML requirements analysis model so that we can confirm validity of(More)
