UML applied to real-time systems
course overview
The course makes extensive use of practical exercises and examples to reinforce points made in the formal presentations. In addition to the UML diagrams, delegates learn the fundamental concepts of object oriented analysis and design including objects, classes, components, architecture and stereotypes.
The notation used is carefully restricted to the UML standard and its extensions and does not introduce any new diagrams or notation within existing diagrams. Delegates also learn how to use the UML within a style of real-time development process. This enables the attendee to understand and apply the various off-the-shelf process models currently available on the market. They will also be capable of contributing to the development or customisation of in-house process models.
Duration: 4 days
target audience
This course is suitable for people who are familiar with basic software engineering problems and techniques — no previous OO knowledge is assumed. In particular, it is aimed at:
- team leaders, systems and applications programmers working on or preparing for projects using Object Oriented technologies;
- analysts wishing to learn OO principles;
- consultants and designers using or providing advice on OO development;
- quality assurance personnel working on projects using OO technologies; and
- project managers who are preparing for projects using OO technologies, or evaluating the technical benefits of the UML.
