Credits: 7 CDUs / 1 Day

Course Level: Intermediate

Prerequisites:
It is recommended that the participants have a working knowledge of object-oriented concepts such as objects, encapsulation, attributes, and operations.

Course Overview:
This course will provide developers with an understanding of the UML diagrams which are used to analyze and capture requirements graphically during the Enterprise Analysis phase of the project.  Emphasis will be placed on the proper usage of UML notation to correctly convey the meaning of the data, behavior, and interface requirements.

Course Highlights:

• Requirements Modeling using UML
• Use Cases and Activity Diagrams
• Capturing Non-functional Requirements
• Refining the Use Case diagram with «Includes» and «Extends»
• Capturing the Interface Requirements
• Capturing Data Requirements with a Class Diagram

Intended Audience:
This course is designed for developers who are interested in learning how to use the UML as a graphical modeling technique for defining, analyzing, and capturing requirements visually.

Workshop Overview:
A hands-on workshop will be used throughout the course to emphasize the concepts learned and allow the students to experience the use of UML diagrams and techniques.  A University Registration System will be used as a Case Study for the workshops.  These workshops will emphasize the creation of the following five most popular UML models for requirements documentation:

• Context Diagram
• Use Case Diagram
• Activity Diagram
• Class Diagram
• Sequence Diagram
