Object Oriented Analysis & Design with UML

All HOTT courses are available face-to-face, remote-live, on-demand or on-site at your facility. 

This OOA&D training course presents the key concepts and methodologies required to perform quality object-oriented software engineering, with particular attention to practical techniques such as use-case and CRC analysis, UML diagramming, and patterns. Students practice applying object oriented analysis during the course to improve software designs and to see how software objects can be altered to build software systems that are more robust and less expensive. 

Students use several methods for analyzing software systems, finding and refining useful classes and relationships between objects. Care is taken not to focus on any one language so that all students can participate in the design exercises without relying on specific programming skills. 

The course emphasizes the most practical analysis and design methods, including the application of use case analysis, CRC analysis, problem domain analysis, activity diagramming, interaction diagramming, and class diagramming. The Unified Modeling Language (UML) is presented in detail and is used in the exercises and case studies. Practical aspects of project management and implementation are presented from the perspective of experienced object system designers. 

Special emphasis is given to the use of object patterns in developing software systems. The students apply their skills in labs that are mini design sessions, during which the instructor helps the students identify and overcome common obstacles that occur during group sessions.

Students Will Learn: 

• Extracting a system's requirements using a use-case driven approach 
• Leveraging the experience of experts by applying analysis and design patterns 
• Defining a set of extensible, reusable software classes (a class library) for the problem domain 
• Building interaction diagrams that define the interactions among the objects that are required to achieve the desired system behavior 
• Defining a set of candidate classes that suitably model a problem domain 
• Establishing metrics, peer reviews and heuristics to improve the quality of the object models 
• Effectively documenting all phases of the software process using UML 
• Applying an iterative and incremental approach to construction of software systems and components 

Course Prerequisites: 

Knowledge of structured programming concepts.

Note: Classes do not have fixed location. Prior to each class they examine the geographical location of the enrolled students and then select a venue that will provide most convenient overall access for the students. Classes are held in hotel conference rooms and exact location is determined 2 weeks prior to the course date.
