Object Orientated Software Development
EDepot System OOAD

Outline of Problem
In this assignment I have been asked to employ an Object Orientated Analysis & Design (OOAD) process in designing an eDepot System from a requirements document and use Unified Modelling Language (UML) to diagrammatically model the eDepot systems functionality.
For this there will be 10 sections which I have been asked to produce and for each section I will complete the task asked for each. The information about the eDepot system in each section will be:
1) UML Use Case Diagram
2) List the Nouns from the Requirements Document
3) Revised list of Nouns that specify Candidate Classes
4) UML Class Diagram
5) Identification of Class Attributes
6) UML State Diagram
7) UML Activity Diagram
8) Identify Class Operations
9) UML Communication Diagram
10) UML Sequence Diagram

Requirements Document
In this document I have been told that the requirements of the eDepot system is that it is designed to manage a collection of Heavy Goods Vehicle depots for a haulage company. Associated with each depot will be a collection of vehicles, drivers and a depot manager who is responsible for organising a work schedule between different vehicles and drivers.
The different type of vehicles available are trucks and tankers which share common attributes such as vehicle make, model, registration number and service history. There some attributes which are unique to one of the two types of vehicles such as trucks will have a maximum cargo capacity and tankers will have maximum liquid capacity and type. (I.e. chemicals, oils, foodstuffs).
With the system all users will have a username and password which they will enter into the system when logging on to gain access to their work schedule and in the case of depot managers, organise a work schedule between vehicles and drivers which are
