Development of Encapsulated Class Complexity Metric

AbstractSoftware based system is increasing dynamically over the past decades. Safe and reliable software operation is a significant need for many types of systems. Higher complexity in the software decreases reliability of software. The paper aims to find out the role of Encapsulation in improving reliability of an object oriented design. It is found that higher encapsulation in design increases reliability and decreases complexity of design. Node-Host (N-H) approach is proposed to increase encapsulation of the design. An Encapsulation Class Complexity Metric (EC2M) is proposed to measure complexity of a class design. The same has been implemented for the two versions of designs, one is Design 1 and other is modified design of Design 1 named as ReDesign-1 to evaluate the value of proposed metric
