The document discusses object-oriented analysis and design (OOAD), including an introduction to basic OO principles like encapsulation, abstraction, hierarchy, and modularity. It then covers various techniques for object-oriented analysis like noun lists and use cases. Finally, it discusses the process of transforming analysis models into design models using object-oriented design.
Unified Modeling Language (UML) is a modeling language, used for design. Designed based on OMG Standard, Object this helps to express and design documents, software. This is particularly useful for OO design. Here is a brief tutorial that talks about UML usage.

The objective is to explain how a software design may be represented as a set of interacting objects that manage their own state and operations and to introduce various models that describe an object-oriented design.
This Presentation contains all the topics in design concept of software engineering. This is much more helpful in designing new product. You have to consider some of the design concepts that are given in the ppt

This is the most important topic of OOAD named as Object Oriented Testing. It is used to prepare a good software which has no bug in it and it performs very fast. <a href="https://harisjamil.pro">Haris Jamil</a>

Editor's Notes
Before moving on, ask the students to name the four basic principles of OO (as a review).
Discuss what makes a good abstraction with the students: Concise, Represents a single coherent concept, etc.
Encapsulation is putting the “databits” and operations that manipulate them in the same place. Encapsulation DISALLOWS direct manipulation of things that have been encapsulated without utilising the supplied interface. Another example - the accelerator on a car. You put your foot down and car goes faster - this works on most cars, and you don’t worry about the cables, electronics, engine, etc.
Modularity supports separation of concerns. Another example of modularity is a car, which is made up of a body, chassis, engine, wheels, etc.
Hierarchy is not an organizational chart. Hierarchy is not a functional decomposition. Hierarchy is a taxonomic organization. The use of hierarchy makes it easy to recognize similarities and differences. For example, in botany, plants are organized into families, chemistry uses a periodic table to organize the elements. Another example -- telephone number, then a 0800 (free call) number, premium rate number, etc
Review the 4 basic principles of OO (abstraction, encapsulation, modularity, and hierarchy) and why they are good. Ask the students to name the OO concepts (e.g., class, package, interface, etc.) that support those principles. Emphasize that OO facilitates the following best practices: Develop Iteratively Model Visually Use Component Architecture
