Introduction

UML concepts to be introduced and illustrated by examples will include:

• UML (Unified Modelling Language) is a modelling language using text and graphical notation for documenting specification, analysis, design and implementation of OOSD (Object-Oriented System Development) process.
• It is the recommended OMG (Object Management Group) standard notation for visual modelling with well-defined syntax and semantics.
• Logical, Component, Process, Deployment and Use case views (the ``4+1 view'') of UML's architecture for complex systems development will be discussed.
• UML can be used with all processes throughout the development life cycle and across different implementation technologies. A unified approach to the methods in a development process has been made by Booch et. al. (discussed in a recent book on Unified Software Development Process), but is not the concern of UML.
