different levels of familiarity with libraries. In this paper, we propose a Software Reuse Framework ŽSRF. for overcoming the above drawbacks. Based on a built-in hierarchical thesaurus, its classification process may be made semi-automatic. SRF is a domain-independent framework that can be adapted to various libraries and also provides four search levels to serve users with different levels of familiarity with libraries.

IEEE, Los Alamitos, CA, USA,97CB36112. p 32-37 CODEN: PSICD2 ISSN: 0730-3157 Publication Year: 1997 Abstract: In this paper we present an approach to manage evolutionary changes that take place over time in an objectoriented software metrics database schema. Our framework is based on Entity-Relation ŽE-R. model and uses a recursive graph structure, known as R-graph, to support the views of software quality and risk. The fundamental mechanism for abstracting views is the introduction of two semantic operators for the R-graph. These operators are proposed based on graph-based predicates and Petri-net based predicate formalism for view abstraction. ŽAuthor abstract . 10 Refs.

Source: Computer v 30 n 10 Oct 1997. p 43-44 CODEN: CPTRB4 ISSN: 0018-9162 Publication Year: 1997 Abstract: Is there a way to develop software that is of higher quality and yet takes less time and effort to produce? Many software developers believe there is, through reusing high-quality, tested software already developed. Unfortunately, software reuse has proven difficult to achieve. Organizations attempting to implement a software reuse program face both technical and nontechnical problems. What do software developers have to do to successfully implement reuse? In 1995, George Mason University undertook a study to investigate the relationships between software reuse investment and capabil-
ity, productivity, and quality, as well as many of the theories proposed by the literature. The study found that a product-line and software architecture approach are higher predictors of decreased effort and increased quality than software reuse alone. On the other hand, it found no relationship between software reuse capability and the library approach. ŽAuthor abstract . 1 Refs.

IEEE, Piscataway, NJ, USA,97CH36015. p 683-689 CODEN: NASEA9 Publication Year: 1997 Abstract: Program restructuring is frequently part of software reengineering and maintenance activities. There are several goals: reduce future system life cycle costs and improve quality by reducing software faults. An important sub goal is to reduce the number of non-traversable program execution paths. The conjecture is that non-traversable execution paths make programs hard to understand and maintain. Unfortunately, reducing the number of non-traversable paths frequently produces unstructured programs, which are also commonly believed to make program understanding and maintenance more difficult. Pleszkoch, Linger, and Hevner described a technique in which the final result of a restructuring process is an equivalent system that is both structured and has fewer non-traversable paths. Their restructuring technique involves creation of a set of intermediate transformations, some of which may produce unstructured programs, even though the final output is structured. We describe the results of a series of experiments on the effect of program restructuring on comprehension. There were several objectives: to determine if this technique produced programs that were easier to understand than their original versions, to see if understanding was
