Fast Track to Object Oriented Analysis and Design (OOAD) with UML

Fast Track to Object Oriented Analysis and Design with UML

TT1110

Introductory

3 Days

Course Overview

Fast Track to Object Oriented Analysis & Design with UML is a three-day, fast-paced hands-on course that provides students with a solid foundation to move into an OO programming environment.  This course takes advantage of several of the latest features in UML and incorporates several of the newest techniques and approaches for improving OOAD. This course focuses on the advantages of the OO paradigm and domain modeling in reducing the representational gap between a target domain and the software application itself.  Minimizing this gap leads to more effective solutions that are both flexible and robust.  

 

NOTE: This course is a fast-track subset of our five-day, more comprehensive TT1130 OOA&D using UML course. 

Course Objectives

 

The course includes coverage of the most effective techniques in use today, such as Use Case analysis, static and dynamic system modeling, responsibility driven design, Design Patterns, using UML to document designs, and much more. The focus of the course is to give a practical approach to producing high quality object-oriented software designs and to provide the knowledge and experience necessary to avoid the most common risks associated with building production systems. Properly assigning responsibilities to classes is one aspect of detailed design that is particularly important.  This course pays special attention to that particular design activity, looking at GRASP (General Responsibility Assignment Software Patterns) patterns and how they can be applied to real design problems. 

 

Working in an engaging group exercise and hands-on “thinking and drawing” environment, students will: 

  • Learn the three pillars of building a system; The Model, The Process, The Best Practices  

  • Have a good, working definition of object-oriented programming 

  • Understand the object-oriented model, including types, objects, encapsulation, abstraction, messaging, protocols, inheritance, polymorphism, relationships, and coupling, strengths and weaknesses  

  • Understand the concept of representational gap between an application and its targeted domain  

  • Relate how Domain Modeling minimizes the representational gap between domain and application 

  • Learn how to read and create the most important UML diagrams  

  • Recognize the difference between analysis and design  

  • Be able to produce a requirements analysis  

  • Know how to create Use Cases, recognizing and avoiding bad use cases 

  • Effectively perform object discovery using such tools as category lists and use cases to harvest candidate objects 

  • Learn how to create a static conceptual model of your system  

  • Learn how to create a dynamic behavioral model of your system  

  • Understand how to move from analysis to design  

  • Effectively identify relationships amongst objects, understanding when to show those relationships and when not to 

  • Effectively assign responsibilities using the patterns and principles of GRASP (General Responsibility Assignment Software Patterns) 

  • Understand Design Patterns and their importance  

  • Learn how to apply Design Patterns to refine your model  

  • Understand the uses of inheritance, where it is appropriate, and where it is not  

  • Recognize the abuse of inheritance 

  • Understand the importance and use of interfaces  

  • Recognize rich versus anemic domain models 

  • Understand how to move from design to implementation 

Course Prerequisites

This is a beginner level programming course, designed for developers or technical managers who specify, design and develop software and applications using traditional/formal/structured methods and want to learn to use an object-oriented approach.  Ideally students should have some working knowledge of a procedural programming language and syntax, such as C. 

 

Attendees can include systems and software analysts and designers, programmers who read and implement program designs, personnel involved in inspections and design/code walk-through, software project managers managing large (re-use) projects, and maintenance personnel involved in maintaining and re-engineering software products. This course is also highly beneficial for those who specify requirements and business rules for systems. 

 

Attendees should have a working knowledge of developing software applications.  Designing and analysis experience is also extremely beneficial.  This is not a coding class.
