Building Evolvable Software Using Normalized Systems Theory: A Case Study

Abstract

Normalized Systems (NS) theory has recently been proposed as an approach to develop agile and evolvable software by defining theorems and design patterns for software architectures. In this paper we discuss the NS development process, which is illustrated by means of an elaborate description of a case regarding a budget management application developed according to the theory. Advantages of the NS approach, such as swift application development through code expansion and the transfer of additional NS design knowledge to new applications, are equally discussed.
