Case Study, Chapter 2
Chapter 2 is a step-by-step case study on "the design of a 'What-You-See-Is-What-You-Get' (or 'WYSIWYG') document editor called Lexi." (pp33)
The chapter goes through seven problems that must be addressed in order to properly design Lexi, including any constraints that must be followed. Each problem is analyzed in-depth, and solutions are proposed. Each solution is explained in full, including pseudo-code and a slightly modified version of Object Modeling Technique where appropriate.
Finally, each solution is associated directly with one or more design patterns. It is shown how the solution is a direct implementation of that design pattern.
The seven problems (including their constraints) and their solutions (including the pattern(s) referenced), are as follows:

Famous quotes containing the words case and/or chapter:
“... business training in early life should not be regarded solely as insurance against destitution in the case of an emergency. For from business experience women can gain, too, knowledge of the world and of human beings, which should be of immeasurable value to their marriage careers. Self-discipline, co-operation, adaptability, efficiency, economic management,—if she learns these in her business life she is liable for many less heartbreaks and disappointments in her married life.”
—Hortense Odlum (1892–?)
“When one man dies, one chapter is not torn out of the book, but translated into a better language.”
—John Donne (c. 1572–1631)
