The automatic extraction of high-level structural information from code is important for both software maintenance and reuse. Instead of using specialpurpose tools, we explore the use of a general-purpose data visualization system called Hy+ for querying and visualizing information about object-oriented software systems. Hy+ supports visualization and(More)
We report on a combination of system theoretic simulation modeling methodology with the JavaBeans component model as a basis for a component-based simulation framework. While system theory formalisms can serve as formal, mathematical foundations for modular, hierarchical modeling and simulation, the JavaBeans component model provides the appropriate(More)
Object-oriented programming improves the reusability of software components. Extensive reuse of existing software enhances the importance of documentation. To increase productivity in documenting and to make the structure of documentation better suitable for object-oriented software systems, we suggest applying object-oriented technology to the(More)
Security design patterns are proven solutions to security problems in a given context with constructive measures of how to design certain parts of a software system. The literature contains numerous definitions, examples, and taxonomies of such patterns. There are also a few quality criteria for them. We suggest a new taxonomy based on attack patterns in(More)
Software reuse provides several advantages, e.g., increased productivity and software quality, decreased development time and costs. Installing reuse programs requires up-front investments. Empirical data showing that a potential for software reuse exists in a certain environment will help managers to decide on such investments. In order to determine the(More)
This paper describes a tool that helps programmers understand object-oriented software systems written in C++, a language that is expected to gain widespread use in industry. This task is accomplished by providing information about the set of classes and files comprising the system and the relationships among them. The tool described enables its users to(More)
