Advanced Structural Modeling

                                                                      Unit II                                                     Advanced Structural Modeling  A relationship is a connection among things. In object-oriented modeling, the four most important relationships are dependencies, generalizations, associations, and realizations.  Graphically, a relationship is rendered as a path, with different kinds of lines used to distinguish the different relationships. Dependency A dependency is a using relationship, specifying that a change in the specification of one thing may affect another thing that uses it, but not necessarily the reverse. Graphically, a dependency is rendered as a dashed line  A plain, unadorned dependency relationship is sufficient for most of the using relationships you'll encounter. However, if you want to specify a shade of meaning, the UML defines a number of stereotypes that may be applied to dependency relationships. There are 17 such stereo

Design Patterns UNIT-2

 A Case Study: Design a Document Editor ¾     This chapter presents a case study in the design of a "What-You-See-Is-What-You-Get" (or "WYSIWYG") document editor called Lexi. ¾     We'll see how design patterns capture solutions to design problems in Lexi. ¾     A WYSIWYG representation of the document occupies the large rectangular area in the center. ¾     The document can mix text and graphics freely in a variety of formatting styles. ¾     Surrounding the document are the usual pull-down menus and scroll bars, and a collection of page icons for jumping to a particular page in the document.    Design Problems: Seven problems in Lexis's design: Document Structure: The choice of internal representation for the document affects nearly every aspect of Lexis's design.    All editing, formatting, displaying, and textual analysis will require traversing the representation.   The way we organize those impacts design information.

Two dimensions: 1.Thought processes and reasoning (internal) 2.Behavior (external) Two factors for measuring success along each dimension: 1.Success in terms of fidelity to human performance 2.Success in terms of an ideal performance measure, called rationality. Acting humanly: Turing Test •Turing Test -- Proposed by Alan Turing in 1950 -- Designed to provide a satisfactory operational definition of intelligence -- A computer passes the test if a human interrogator, after posing some written questions, cannot tell whether the written responses come from a person or from a computer -- No physical interaction between the interrogator and the c
