Fundamental Patterns for Object Oriented Systems Designing

Note: Please note that training delivery does not happen as frequent as it was used to be due to other engagements of the trainer. This applies to both public and corporate training programs. Resumption of training activities to normalcy may not happen very soon. You are kindly requested to seek training from other sources.

Description:

How to create a good object oriented design for a software system? Is it possible to follow a systematic approach where requirements are translated though analysis to a good design? What are the best practices that can be applied in doing so? This training program teaches you how to write use case as a means to capture requirements, object oriented analysis and applying fundamental patterns to create good object oriented designs. Content of the training primarily revolves around Generalized Responsibility Assignment Software Patterns (GRASP Patterns) that are primitive, but powerful concepts that can be applied in creating good object oriented designs.

Training Objectives:

At the end of the training, participants will be able to

  1. Capture functional requirements of a system using use cases.
  2. Write effective use cases so that they can easily be used during analysis and designing of object oriented systems.
  3. Define the meanings and purposes of Object Oriented Programming (OOP) fundamentals with sound clarity and apply them correctly
  4. Use UML use case diagrams, class diagrams and sequence diagrams to visually document use case model, domain model and design of the system.
  5. Analyze and design object oriented systems in a methodological manner backed by fundamental patterns and sound principles.
  6. Apply GRASP patterns in designing object oriented systems
