Analysis and Design with the UML ( Unified Modelling Language)

·       UML = Analysis and Design with Pictures

                                                       (Diagrams)

Unified = together – historically different methods

                   combined into one.

·       Analysis = What to Build.

1. High level conceptual model

   e.g For a Bank System.

   Entities

   Bank, Account, Customer.

   Relationships

   Customer has an Account.

   2. High Level Model of Solution

   Models to show how components of the system 

   cooperate to produce required behaviour.

·       Design = how to build on available

                  hardware/software

               e.g Java program or JSP/Web

                     use Oracle or XML database

·       Beware – All levels may use the same diagrams.
