ABSTRACT

This chapter explores and probes the Accessibility stable analysis pattern. The pattern gives an excellent start to software developers, by defining the core knowledge of any accessibility problem. The chapter demonstrates accessibility pattern's utilization by two significant software applications, which have an access to Internet contents and student's information access system. It aims at building a stable pattern that captures core knowledge of the accessibility concept, so that the core concepts are extendable upon to produce long-lasting, stable programs. The chapter provides a solution for the fundamental problem of developing a pattern that captures the atomic accessibility notion. Quantitative measures rely on factors such as enduring business themes (EBTS), number of business objects (BOs) and industrial objects (IOs) that are required for specific applications, constraints, classes required, division of class functionality, number of operations to be implemented in a class, inter-dependency of classes, and depth of inheritance.
