Overview:
Analysts, Developers, and software Architects require a solid understanding of object oriented principals to analyse and design effective object oriented solutions. The OO (Object-Oriented) approach, however, is radically different than traditional design, an Object Oriented system is one that is:
- Real-world in its purpose - every part has a purpose that is straightforward to explain, even to a non technical audience
- Modular - easy to buy, build & replace parts, even with different technologies and languages
- Reusable - each building block can be reused by other systems
- Loosely coupled - the modules can work within heterogeneous environments
- Readily scalable to cope with increased demand
- Incremental in its delivery - the system can be bought or built and improved upon in repeated development efforts
The concepts used in Object-Oriented design are equally applicable in capturing and defining Business processes. Whether your emphasis is on Business Analysis or System Analysis and Development, OO concepts are essential to understand in order to exploit the Unified Modelling Language for defining and communicating all aspects of Business processes, data flow, and software driven systems.
This 1-day course begins by laying down a solid foundation of the underlying concepts of object oriented thinking. Core concepts such as properties, methods, inheritance, polymorphism, overriding and overloading of methods, and encapsulation are explained in detail. After laying out the concepts, the course continues to cover design principles associated with designing classes and objects. Finally the business case for OO Design and Development is examined, and UML is introduced.
