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. Programming languages have appearances (“syntax”), meanings (“semantics”), and efficiencies (“pragmatics”). of interfaces. Object-orientation is what’s referred to as a programming paradigm. A really good “extensible language” will allow each of these to be extended (and in large ways when this is a good idea).

Object-Oriented Metrics Measurements can be extensively arranged into three classifications: venture measurements, item measurements, and process measurements. Benefits of Object-Oriented Approach. No, not by copying and then pasting the same code from one block to another and from there to another and so on. The most intuitive reuse is in the reality of “plug-and-play” just like the hardware counterpart.

We pride ourselves on delivering simple, effective solutions that drive savings and sustainability. If everything we do in these languages is object-oriented, it means, we are oriented or focused around objects. Reusibility vs Extensibility in OOAD 1. In recent years, computer software is the single most important technology in the world. In programming, reusable code is the use of similar code in multiple functions. 1.

Whenever we can reuse existing components for a product we potentially gain additional time which can then be used to address the novel aspects of our application, or simply deliver it earlier. The work presented in this paper can be effectively used to calculate the reusability of any object oriented software module. 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. Extensibility as follows: But what is meant by reuse? 2. Instead, code reusability defines the methodology you can use to use similar code, without having to re-write it everywhere. object oriented system/programming . Thus, this work concentrates on reusing a “design model” and monitoring reuse as the model evolves. USABILITY TESTING is a type of software testing done from an end-user’s perspective to determine if the system is easily usable.
