This document discusses Object-Oriented Analysis and Design (OOAD). It defines objects and classes, with objects being concepts or things and classes being groups of similar objects. OOAD models a system as interacting objects. Benefits include tackling complex problems, improved communication, reusability, and consistency across models. The analysis phase develops a model of the application, the design phase refines this, and the implementation phase codes the design. Examples of an activity diagram, communication diagram, class diagram, and sequence diagram are provided to illustrate OOAD modeling.
Ooad (object oriented analysis design)
- 2. Object and Classes run through Object: Is a concept or thing or activity Class: it is a group of objects with similar properties, common behavior, common relationship to other objects
- 3. What is OOAD In the 1990s, Coad incorporated behavioral ideas to object-oriented methods. Object oriented analysis and design is a software engineering approach that model a system group of interacting objects.
- 4. The Object-Oriented Modeling Approach Benefits 1.The ability to tackle more challenging problem domains 2.Improved communication among users, analysts, designers, and programmers 3.Reusability of analysis, design, and programming results 4.Increased consistency among the models developed during object-oriented analysis, design, and programming A.4
- 5. How to create OOAD models Analysis Phase Model of the real-world application is developed showing its important properties Model specifies the functional behavior of the system independent of implementation details Design Phase Analysis model is refined and adapted to the environment Implementation Phase Design is implemented using a programming language or database management system A.5
- 6. Example case study Say hello Offer cart
- 8. Wait for Customer Offer card SmileSay hello Get cart No Customer Refuses Cart
- 9. Classifying the objects in the use case greet by using analytical class Classification of objects Boundary Class Door Entity class Shopping Cart Greeting Shopper Control class Greeting Step
