| Abstract | Cohesion and coupling are internal software attributes, which tell how tightly the components of software module are bound together in design or implementation. Cohesion and coupling are the desirable goal in software construction, leading to better values for external attributes such as maintainability, reusability, and reliability. Object-oriented (00) system development is gaining wide attention both in research environment and in industry. A severe problem is encountered, however, is the quickly increasing complexity of such systems and the lack of adequate criteria and guidelines for good designs. To cope with this problem it is imperative to better understand the prope11ies and characteristics of object-oriented systems. Cohesion describes the binding of elements within one method and within one object class, respectively. Coupling describes the interdependency between methods and between object classes, respectively. Considering all the features of object-orientation the coupling in object-oriented system has been categorized. A model has been presented for measuring direct coupling of 00 system, which is then used to identify components with the objective of encapsulating higher coupling objects into the components. Some ways has been suggested for which an 00 approach can be developed with high cohesion and low coupling. Relationships between two well-known and widely accepted measures of cohesion have been shown. The effects of Public members, Private members, Constructors, Destructors and Inheritance in measuring cohesion have been analyzed tlu·ough principal component analysis. Some statistical analysis has been shown to validate the proposed measures. |
