Study Notes
Object-Oriented System Development
- Object orientation is an approach in software technology that supports the development, enhancement, and maintenance of complex enterprise IT systems.
- It views complex systems as an interaction of abstract or real entities, known as objects.
The Concept of Object
- An object is a part of a software system.
- An object can contain attributes and methods.
- Attributes are used to store information, such as current values of variables, in an object.
- Attributes of an object are hidden from direct access from other objects and are thus protected (principle of data encapsulation).
- Methods are used to create, read, change, and perform calculations of the values of attributes.
Phases of Object-Oriented Development Process
- Object-Oriented Analysis (OOA): determines what a system should do.
- Object-Oriented Design (OOD): forms a bridge between the analysis and implementation.
- Object-Oriented Programming (OOP): translates a system design into functioning program code.
Benefits of Object Orientation
- Supports the creation, enhancement, and maintenance of complex enterprise IT systems.
- Achieves quality goals such as simple extensibility, better testability, and better maintainability.
Example of Object Orientation: Digital Clock
- A digital clock can be replicated as a digital object with attributes such as "current time" and "current time zone".
- Methods of the digital clock object can include "set time", "output time", and "set time zone".
Example of Object Orientation: Coffee Machine
- A coffee machine can be viewed as an interaction of cooperating objects, such as water tank, water pipe, non-return valve, heating element, hot plate, and filter.
- Each object has a specific responsibility and interacts with other objects to achieve a common goal.
Summary
- Object orientation is an approach that supports the creation, enhancement, and maintenance of complex enterprise IT systems.
- It views complex systems as an interaction of cooperating objects.
- The object-oriented development process consists of object-oriented analysis, object-oriented design, and object-oriented implementation.
