Study Notes
Objectives
- To understand why Object-Oriented (OO) is used in software construction
- To know what Object-Oriented Analysis and Design (OOAD) is
- To learn how to do OOAD
What is OOAD?
- OOAD is a notation, similar to languages like English, Elvish, and Ku
- It involves using Object-Oriented (OO) methodology to analyze and design systems
How to Do OOAD
- Where to use OO: Systems Engineering, Quality Assurance, Requirements Analysis, Project Planning, Maintenance, Architectural Design, Detailed Design, Implementation, and Release
- Importance of notation vs. process in OOAD
- OOAD involves using Object Modeling Technique (OMT) by James Rumbaugh
- OMT consists of:
- Object Model: describes the static structure of objects and their relationships
- Dynamic Model: describes the interactions among objects
- Functional Model: describes the data transformation of the system
History of OOAD
- Historical perspective of OO technology and process
- Evolution of OO programming languages, design, and analysis
OO Development Processes
- Some popular OOAD processes:
- Fusion
- Recommended Process and Models
- The Rational Unified Process (RUP)
- Importance of using OO design patterns for reusable solutions to typical problems
- Design patterns have:
- Name: identifies a particular pattern
- Problem: identifies context when pattern should be applied
- Solution: abstract description of a design problem with a template object design
- Consequences: results and trade-offs of applying the pattern
Why Object-Oriented
- Who's behind object-orientation: knowledge, representation, psychological validity, philosophical validity, and computational validity
- Concerns: databases, emphasis on persistent data, relational databases, network databases, and hierarchical databases
- Object-oriented programming languages: Simula, Smalltalk, C++, Protel, Java
Introduction to OOAD - Summary
- Why OO: software crisis due to communication and complexity, languages, concepts, and models
- What is OOAD: fundamental OO concepts, a little taste of UML
- How to do OOAD: OO development processes and design patterns
This quiz covers the basics of object-oriented analysis and design, including the importance of OOAD, its notation, and where to apply it. It also touches on systems engineering and quality assurance.
