This course focuses on the design issues associated with enterprise software applications, especially interactive, data-intensive applications. The course touches on all aspects of design, including the user interface, data and component design, procedure design, and design for controls and security. The main design approach taken is based on object-orientated systems described by UML and other techniques. There is however a brief review of structured systems analysis and design models and techniques. The design techniques utilised are technology and product agnostic.
This course is suitable preparation for delegates wishing to take the BCS Certificate in Systems Design Techniques.
Prerequisites
Attendance at a Systems Modelling Techniques course, UML version (SMTU), or the equivalent knowledge of UML Analysis Models is essential. In particular delegates are expected to be familiar with the concept of Use Cases, and familiar with the analysis level of UML Class Modelling, Activity Diagrams, Interaction Diagrams and State Machines.
