Overview

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.

Target Audience

  • Those who need to produce effective design specifications for developers, as part of integrated software development initiatives
  • Those who wish to learn how to progress the deliverables produced by analysis techniques into design artefacts for object-orientated systems
  • Those wishing to attain the BCS Certificate in Systems Design Techniques

If you are taking a BCS exam you must bring photographic identification with you (passport, driving license or student card), as it is a BCS requirement to produce it for the invigilator prior to the exam. Failure to produce a valid form of photographic identification will result in a candidate not being able to sit the exam. For any questions about what form of identification is acceptable please contact your Account Manager or the QA Examination Administration team on 44 (0)1793 696273.

BCS allow additional time for candidates who have a disability or whose native language differs to that of the examination paper. Full details are provided in the BCS Reasonable Adjustments Policy which is available to view on the BCS website. If you believe you qualify for this then please notify the Exam Administration team on the details below as early as possible. At least two weeks' notice will be required for processing this request. Delegates failing to advise QA and provide evidence when requested, may not be allowed the additional support offered via the BCS policy. QA Exam Administration can be contacted by email exam.admin@qa.com or by phone 44(0) 1793 696162.

Following your exam you will be sent an email from BCS asking you to register. Once you have registered and your exam results become available then you will be able to log back into your account and view your results.

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.

Learning Outcomes

  • Understand the choices available for the design of application architecture
  • Apply design criteria to the task of data componentisation, the use of services and interfaces
  • Use UML Interaction diagrams to support the design of classes and object collaboration
  • Develop a logical data model from a conceptual data model
  • Design procedure logic using a range of techniques
  • Apply the rules of normalization to a set of data attributes
  • Design Logical Access Paths
  • Design a Star Schema
  • Apply design techniques and principles to the design of user interfaces
  • Understand and apply design principles to the security themes of confidentiality, integrity and availability
