Stable Design Patterns for Software and Systems

"Software stability concepts have shown great promise in the area of software reuse and lifecycle improvement. These innovative concepts produce unique models that are both stable over time and across various paradigm shifts within a given application context. The important idea behind stable design patterns is to design and create an enduring solution to the problem under consideration, with the goal of increased stability and broader reuse. This book presents novel, pragmatic approaches to understanding and solving software stability challenges."--Provided by publisher Attention to design patterns is unquestionably growing in software engineering because there is a strong belief that using made to measure solutions for solving frequently occurring problems encountered throughout the design phase greatly reduces the total cost and the time of developing software products. Stable Design Patterns for Software and Systems presents a new and fresh approach for creating stable, reusable, and widely applicable design patterns. It deals with the concept of stable design patterns based on software stability as a contemporary approach for building stable and highly reusable and widely applicable design patterns. This book shows that a formation approach to discovering and creating stable design patterns accords with Alexander's current understanding of architectural patterns. Stable design patterns are a type of knowledge pattern that underline human problem solving methods and appeal to the pattern community. This book examines software design patterns with respect to four central themes: How do we develop a solution for the problem through software stability concepts? This book offers a direct application of using software stability concepts for modeling solutions. How do we achieve software stability over time and design patterns that are effective to use? What are the unique roles of stable design patterns in modeling the accurate solution of the problem at hand and in providing stable and undisputed design for such problems? This book enumerates a complete and domain-less list of stable patterns that are useful for designing and modeling solutions for frequently recurring problems. What is the most efficient way to document the stable design patters to ensure efficient reusability? This book is an extension to the contemporary templates that are used in documenting design patterns. This book gives a pragmatic and a novel approach toward understanding the problem domain and in proposing stable solutions for engineering stable software systems, components, and frameworks. 9.2.8 Applicability with Illustrated Examples -- 9.2.8.1 Case Study: A Hospital Scenario -- 9.2.8.2 Scenario Use Case -- 9.2.9 Modeling Issues -- 9.2.9.1 Abstraction (for AnyEvidence BO) -- 9.2.9.2 Use of a Static Model (.
