60 -- No.10, pp. A really good “extensible language” will allow each of these to be extended (and in large ways when this is a good idea). A New Reusability Metric for Object-Oriented Software, Software Quality Journal, Vol 7 no. No, not by copying and then pasting the same code from one block to another and from there to another and so on. USABILITY TESTING is a type of software testing done from an end-user’s perspective to determine if the system is easily usable. The concept of an interface is old. The MOOD Metrics Set, Proc. 4. In other words, a framework that describes the reusability of software and that structures appropriate metrics in a way that is easy to use is requisite in effective reusability assessment (Hristov et al, 2012). 50. It is good to use interfaces in large type of applications because interfaces make … We use cookies to ensure that we give you the best experience on our website. 1. Its benefits include reusability, refactoring, extensibility, maintenance and efficiency. • Frameworks Encapsulation 3. Subramanyam, R., Krishnan, M.S. GIve differences in 4 unique and basic terms of UML, classification , definitions ,frameworks. The issues are technical, not managerial. It improves testability through encapsulation. OO Technology and Reuse One of the major benefits of OO technology, as claimed by its proponents, is that it enables reuse. Maintenance Metrics for the Object Oriented Paradigm, First International Software Metrics Symposium. Software reusability can encourage innovation in traditional development methods and also it is a cost effective option. Object-oriented metrics -- a survey, proceedings of the FESMA 2000, Federation of European Software Measurement Associations, Madrid, Spain. Extensibility as follows: A design pattern is a microarchitecture that provides a proven solution to design problems that tend to recur within a given application or software development context. Software reusability is changing the way programmer’s code and organizations operate. If you have designed any object that is responsible for creating and maintaining the lifecycle of another object, you have used the Factory pattern. Object-Oriented Software Metrics", Prentice Hall. Components should be designed to work on different context. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

The suite, based on CK metrics [1], was applied to three C++ programs to measure inheritance, coupling, and cohesion. https://dl.acm.org/doi/10.1145/2492248.2492264. What is OOPs ? We have found that multilevel inheritance has more impact on reusability among these three features. There are two categories of elements in an object-oriented system − Major Elements− By major, it is meant that if a model does not have any one of these elements, it ceases to be object oriented. This paper presents one such empirical study to evaluate a suite of object-oriented (OO) metrics, using OO characteristics such as multilevel inheritance, multiple inheritance, and hierarchical inheritance, to find their impact on reusability. How can the authors be so confident in their suite, and results, with such weak evidence__?__ "Neither ever quite the same, nor ever quite another". Chidamber, S. and Kemerer, C. 1994. The implementation of the creational pattern is responsible for managing the lifecycle of the instantiated object. The four major elements are − 1. 2003. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class.

And object-oriented metrics identify the effectiveness of each reuse strategy. In computer science and software engineering, reusability is the use of existing assets in some form within the software product development process; these assets are products and by-products of the software development life cycle and include code, software components, test suites, designs and documentation. e)SAD is mature and widespread. Looks like you’ve clipped this slide to already. • UML Extensibility is a measure of the ability to extend a system and the level of effort required to implement the extension. • Classifications Chidamber, S. R., Kemerer, C. F. 1994. During the software development life cycle, development is typically broken up into stages, which are loose, abstract concepts used to separate the activities taking place within each phase of development. Modularity 4. reusability of components (Sandhu, Kaur, & Singh, 2009). The authors refer to their own paper [2] when presenting the suite, so the reader is forced to go look it up. Henderson-sellers, B. Whether you agree or not, there is no commonly accepted definition of Object-Oriented Design (or Development, or Programming) (OOD, OOP). Reuse library standards aid users in setting up organizational reuse programs, Embedded Systems Programming Product News. It contains both data and functions which act on data. REUSABILITY 1. The authors conclude that multilevel inheritance has the largest impact on reusability. … Reusability: The Case for Object-Oriented Design.

Liang,V., and Colemon, C., "Principal Components of Orthogonal Object Oriented Metrics", Software Assurance Technology Center, White Paper SATC-323-08-14, NASA Goddard Space Flight Center, Greenbelt, Maryland 20771. Analysis of Quality of Object-Oriented Systems using Object-Oriented Metrics, Electronics Computer Technology (ICECT), 2011 3rd International Conference on, April 8-10, 2011. The use of OOAD both in the development of new systems and in their conversion from legacy procedural language implementations favors the discovery and use of design patterns. So I will make up some definition: Object-Oriented Designis a software development approach to design and implement software system as a collection of interacting stateful objects with specified structure and behavior. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance. OOAD is best applied iteratively since there is no clear process involved, but each aspect where OOAD is applied is refined as it is reused.

Baltimore,Maryland, May 21-22, 1993. This is because major portions of the designs are based on the entire aspects of the system and on the entities rather than on individual functions and code.  Reliability: Reliability is specified by using mean time to failure. Reusability is one of the quality attribute and it is of prime importance in object oriented software development as reusability leads to increase in developer productivity, reduce development cost as well as reduce time to market. d)SAD has a low reusability .OOAD has a high reusability. Bieman, J., and Karunanithi, S. 1993. 26, Issue 1, July 1994, Pages 87--96. I did find an error in the title of section 6, which is common to both papers. 20, no. Abreu, Fernando B. Object-Oriented architecture reduces the development time and cost. Goel, Brij Mohan, Pradeep, Kumar Bhatia.

Anthes, Software Reuse Plans Bring Paybacks, Computer world, vol. organized will not make the reuse problem go away. The Primary characteristic of software reusability is "the extent to which the software can be used in other applications". A Metrics Suite for Objectoriented Design, IEEE Transactions on Software Engineering, vol. Objectoriented programming helps in achieving the concept of reusability through different types of inheritance programs, which further help in developing reusable software modules. Three programs have been considered as input for the study -- the first program uses multilevel inheritance, the second program uses multiple inheritance and the third program uses hierarchical inheritance. They also note, using the word "proves," that the metrics provide a correct evaluation of OO systems. It falls under non-functional testing.. ISTQB Definition. 8.
