Object-oriented analysis and design using the language UML

Basic knowledge of any object-oriented language is recommended.

This course is intended for analysts, designers, developers, testers and project managers. It is an introduction to system modeling using UML.

Based on selected systems (case study) following phases of system modeling are presented: from modeling requirements, through business process modeling and documentation of functional and non-functional requirements, to the analytical model. The next step is the design phase - static and dynamic modeling using project classes and the interaction between the system components. For exercises is used Enterprise Architect - popular modeling tool.

Training can be the basis for a comprehensive process modeling in enterprise systems through the use of UML in all phases of software development.

Introduction to UML

• A brief History of UML
• Overview of issues in the field of object-oriented modeling
• UML overview

Requirements management

• Requirements Types
• Requirements Categories (FURPS)
• Methods for gathering requirements
• Modeling requirements using UML
• The relationship matrix for the requirements
• Creating a requirements specification

Modeling business processes

• Activity Diagram
• Business process modeling in UML
• The definition of a business process
  • Concurrent flows and decisions
  • Exceptions and Exception Handling
  • Partition, fork, join and other elements

Modeling non-functional requirements

• Components and Deployment diagrams
• The initial architecture of the system - logical and physical
• Modeling requirements for security, performance, reliability, ...

Modeling functional requirements

• Modeling functionality with the Use Case diagram
• Determining the scope of the system
  • Actors and the relationships between them
  • Identifying use cases
  • Association "actor - use case" and its properties
  • The relationship between use cases: include, extend, generalization
• Creating a use case scenarios and generate diagrams from them (activity)

Analytical model of the system

• Using sequence diagrams
  • The types of messages: asynchronous, synchronous, reply
  • Categories of objects: Boundary, Control and Entity
• Modeling the interaction

Static Modeling

• Class Diagram
  • Class, abstract class, interface
  • Association relationship and its characteristics.
  • Other relationships: aggregation, composition, generalization, dependency, association class
• Forward/Reverse engineering (OPTIONAL)
  • Generating source code from the model
  • Generating diagram based on the source code
  • Synchronizing code and diagram

Dynamic Modeling

• Verification of the static model
  • Clarification of method signatures
  • Verification of the class diagram
• The dynamic modeling at the level of method calls
• Sequence diagram on design level
• State Machine diagram (OPTIONAL)
