This empirical research was undertaken as part of a multi-method programme of research to investigate unsupported claims made of object-oriented technology. A series of subject-based laboratory experiments, including an internal replication, tested the eeect of inheritance depth on the maintainability of object-oriented software. Subjects were timed performing identical maintenance tasks on obj...

This paper describes an approach to providing object persistence in object-oriented programming languages without modifying the run-time system or the language itself. By successively applying design patterns such as the Serializer, Factory Method, and Strategy patterns we develop an object-oriented framework for providing object persistence. The advantages of object-orientation are highlighted...

Object-oriented design language research has suggested some basic concepts that object-oriented programming and languages should support. These are: (1) information hiding, (2) data abstraction, (3) dynamic binding, and (4) inheritance. Object-oriented languages are receiving extensive use in artificial intelligence. Although the Ada language possesses the information hiding and data abstractio...

deforestation in the past decades has risen. so, the proper development of human activities in forests requires the environmental limitations to be considered during forests management process. one of the appropriate measures is the determination of ecological vulnerability. in the present study, patom district of kheyrud forest was classified based on the ecological sustainability, using objec...

This paper presents a compiler based approach to automate test case generation. This approach relies on object oriented metrics to identify complex message method sequences in the program. In this approach the compiler compiles the code to generate a graphical model for the object oriented program based on System Dependence Graph. The SDG is augmented with other important information like contr...

For complementing the weakness of Petri nets in terms of naturallity, modularity, and reusability, a number of high-level Petri nets with the concepts of objects were suggested. However, it is di cult to apply these nets for the requirements speci cation of object-oriented software systems because of insu cient supporting of the object-oriented concepts. In this paper, we developed a Hierarchic...

Object-oriented languages and practices have long been regarded by computational scientists as inefficient or difficult to use in the production of highperformance applications. We have shown that the benefits of using object-oriented practices far outweigh a possible small decrease in run-time performance. The Simple Parallel Object-Oriented Computing Environment for the Finite Element Method ...
