Description
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. (These delegates should also book on course code SMTUEX-1). This course may be taken as part of the programme leading to the ISEB Diploma in Systems Development.
Prerequisites
An understanding of the fundamentals of systems development, or attendance of the Systems Development Essentials course.
Candidates with special examination requirements should consult the ISEB web site (www.iseb.org.uk) for the ISEB Special Needs policy. Note that the ISEB must be advised at least four weeks in advance of any special requirements.
Skills
•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
Course Content
Systems Modelling
The need for modelling and modelling standards; Rationale for the selected approach; The approach and a Systems Development Lifecycle; Place of models within the Systems Development Lifecycle; Modelling the system from different perspectives; Interaction of the models; Validating and verifying models
Systems Modelling in Context
Monitoring analysis against business objectives and system requirements; The bridge to design, software package selection, and development
Use Case Modelling
Modelling user requirements; Use cases; Actors and the system boundary; Use case diagrams; Generalising actors and use cases; Use case associations; Use case descriptions – Template, Pre- and Post-conditions, Main and alternative flows
Activity Diagrams
Process modelling; Modelling use case descriptions
Static Modelling of Data
Analysis class modelling rationale; Objects and classes; Representing classes and encapsulation; Defining attributes; Associations; Generalisation, inheritance and abstraction; Class diagrams and object diagrams
Dynamic Modelling
