<h3>Background </h3>

<p>In this assessment, you will create   a UML model of  a customer information system.</p>
<h3>Description</h3>
<p> The  customer information system maintains information about two  different kinds of customers: </p>
<ul>
  <li>Individual customers: For these customers, the  system stores   an ID and the information about a person (name,   home telephone number, and  email).</li>

  <li>Institutional customers: For these customers, the system stores  an ID and  provides the capability of defining one or more contact people for the institution. The system stores  the following   information for each  contact person: name,   home telephone number,  email,  work telephone number, and the job position of the   contact in the institution.</li>
</ul>
<p>Assume that each customer has a unique ID and that IDs cannot be modified. Assume each contact for an institution has a unique name.</p>
<p>  The   system provides the following functions:</p>
<ul>
  <li>Add  a customer into the system</li>
  <li>Look up  a customer given an ID</li>
  <li>Remove a customer from the system given an ID</li>

  <li>Add a new contact for an institutional customer</li>
  <li>Look up  a  contact  given the  ID of the institution and the   name of the contact</li>
  <li>Remove a  contact   given the  ID of the institution and the   name of the contact</li>
</ul>
<h3>Tasks </h3>
<p>The following steps will guide you for completing this assignment:</p>
<ol>
  <li>Follow the technique described in page <a href="javascript:ContentByName('pg-mdlng-class');">1.2.5&nbsp;Modeling 
    Classes</a> to model the customer information system<em></em>. Use Eclipse, <a href="http://horstmann.com/violet/" target="externalWindow">Violet</a>, 
    PowerPoint, or another tool of your choosing to draw a UML class diagram.
    </li>

</ol>
<ul>
  <li>Your UML class diagram should include:
    <ul>
      <li>The classes to model the  customer information system and the different kinds of customers</li>
      <li>
    The association relationships (including the direction, multiplicity, and 
        association attribute)
        </li>
      <li>    The specialization/generalization relationships
        </li>

      <li>    The attributes and methods, including  accessors and mutators (only for the attributes that can be modified)</li>
    </ul>
  </li>
</ul>
<ul>
  <li>    The class that models  institutional customers should include the following methods that handle the collection of contacts (in addition to these, you may need more methods):
            
          
            
        
      
    <ul>
      <li>Method to add a new  contact</li>

    </ul>
  </li>
  <ul>
    <li>Method to look up  a  contact given the name</li>
    <li>Method to remove a  contact given the name</li>
  </ul>
</ul>
<ul>
  <li>The class that models the customers information system should include the following  methods that handle the collection of customers (in addition to these, you may need more methods):

    <ul>

      <li>Method to add a new  customer</li>
    </ul>
  </li>
  <ul>
    <li>Method to look up  a  customer given an ID</li>
    <li>Method to remove a  customer given an ID</li>
  </ul>

</ul>
<ul>
  <li>Use Sun's 
    coding conventions when naming classes, methods, and attributes. </li>
</ul>
<ol start="2">
  <li>Save the UML class diagram in a SVG, GIF, or JPG  format in a file named <em>uml-customer-system</em>. The extension of this file will depend on the format of the image.</li>
</ol>
<h3>Submission</h3>
<p>Upon completion, submit <strong>only</strong> the SVG, GIF, or JPG file <em>uml-customer-system</em>.
  The extension of this file will depend on the format of the image. </p>
