PDF | On Jan 1, , Johannes Sametinger and others published Software Engineering with Reusable Components. Software is rarely built completely from scratch. To a great extent, existing software documents (source code, design documents, etc.) are copied and adapted to.
In Software Reusability, chapter 1, pages , Reusable software engineering concepts and research directions. Design for reuse: In this thesis, the first study was conducted analyzing one-use and equivalent reusable components for the overhead in terms of component size, effort required, number of parameters, and productivity. Reusable components were significantly larger than their equivalent one-use components and had significantly more parameters.
The effort required for the reusable components was higher than for one-use components. The productivity of the developers was significantly lower for the reusable components compared to the one-use components. Also, during the development of reusable components, the subjects spent more time on writing code than designing the components, but not significantly so.
A ranking of the design principles by frequency of use is also reported.
A content analysis performed on the feedback is also reported and the reasons for using and not using the reuse design principles are identified. A correlation analysis showed that the reuse design principles were, in general, used independently of each other. Design with reuse: Through another empirical study, the effect of the size of a component and the reuse design principles used in building the component on the ease of reuse were analyzed.
It was observed that the higher the complexity the lower the ease of reuse, but the correlation is not significant. When considered independently, four of the reuse design principles: well-defined interface, clarity and understandability, generality, and separate concepts from content significantly increased the ease of reuse while commonality and variability analysis significantly decreased the ease of reuse, and documentation did not have a significant impact on the ease of reuse.
Experience in the programming language had no significant relationship with the reusability of components. Experience in software engineering and software reuse showed a relationship with reusability but the effect size was small.
A design pattern is a general solution to a recurring problem. Interface transformation language are used to express how on offered interface can be transformed to the requested interface[Kon95]. Reuse relation The use of soft. Introduction :: Chapter 1 Reuse legacy code, is possible? A component, in an object-oriented extent, represents a set of collaborative classes or only one class and its interfaces. Multilingual components — can be executed on various plataforms. To use it, they need to modify it — now or in the future.
Testing components before integrating them into a system was found to have no relationship with the reusability of components. A content analysis of the feedback is presented identifying the challenges of components that were not easy to reuse.
Features that make a component easily reusable were also identified.
