Systems Modelling Techniques (UML) —  A 4-day course

 Open Public Course Closed In-House Course

Synopsis

In order to communicate system requirements clearly and accurately to both business and IT stakeholders, it is vital for analysts and designers to be able to construct models from a variety of perspectives. In most cases these models will provide the basis for more detailed design.

The starting point for this course is a set of requirements, as defined in the Systems Development Essentials course. It is primarily concerned with modelling systems using UML techniques. It requires delegates to construct diferent types of model reflecting different perspectives and to describe the interactions between them.

At the end of the course delegates may sit an examination to attain the ISEB Certificate in Systems Modelling Techniques. Please see the Systems Modelling Techniques (UML) Exam outline.

Course Objectives

Upon completion of this course, the student will be able to:

• Justify the need for modelling and modelling techniques
• Explain why it is important to model system requirements from different perspectives and identify specific modelling techniques
• Construct a static structure model (class diagram)
• Construct a process model (activity diagram)
• Construct a simple dynamic event driven model (statechart)
• Evaluate how the various models reflect business objectives and system requirements (via critical success factors)
• Appreciate how the various perspectives inter-relate to each other

Prerequisites

• An understanding of the fundamentals of systems development

Delivery

A mixture of lectures, demonstrations and group discussions and exercises.

Publicly scheduled dates, locations, and prices
