This seminar is a straightforward, easy to understand introduction to object-oriented (OO), component-based, and essential modeling techniques for developing requirements, analysis, and design models. It will include the industry-standard techniques of the Unified Modeling Language (UML) but will go beyond them to be sufficient for the real-world development of modern business applications. While objects and components are often used to develop complex systems, learning how to work with object-oriented techniques does not need to be complicated, nor do you need to develop complex documentation to be successful.
