“Designed as a companion volume to the acclaimed Object-Oriented Analysis, this book focuses on the middle part of the software lifecycle: the activity of design. It shows readers how to apply object-oriented design, and how to tailor and expand the method to suit specific organization and project needs. Readers will explore the major issues in OOD; the role of OOD in the systems lifecycle; how to use graphical notation; strategies for creating design; and hints for evaluating the efficiency of a design created with OOD. For software engineers and other users undertaking real-world systems development projects and designing overall software architecture for systems will find this reference approach to improving systems design indispensable.”

“Elements in a coincidentally-cohesive module have no relationship. Typically occurs as the result of modularizing existing code, to separate out redundant code.”
