Question

you will develop a small XML.

XML is used for storing and exchanging information. XML is the most commonly used file format for e-business. It is important to have a grasp of XML.

In XML, you can choose your own tag names. For example, for representing name of a product, you can use <pname>, <prodName> or <productname> as you like. XML has to follow certain syntax rules.  Gentle Introduction to XML (External Link) provides more information about XML. Do the following:

• Do some research and find out what information must be obtained from customer for effective customer relationship management. (The information includes customer name, email, phone numbers etc.).   
• Decide on an XML file structure (also called schema) for storing all your order (products ordered + payment) information. No schema creation or validation is required.
• Create an XML file including payment data using a text editor like notepad.
• Syntax check your xml with an online validator (need to check for XML syntax only). XML Validator (External Link).
• Save your XML into a file and submit before the deadline. (By default, notepad stores files with extension .txt and that is fine. Although XML files usually have the extension .xml, you may want to save the file with .txt extension to upload

• Below is a sample XML file to start with:

  <?xml version="1.0"?>
  <crmDB>
  <customer>
  <customerName>John Doe</customerName>
  <phoneNumber>3092980000</phoneNumber>
  </customer>
  </crmDB>

    

  Obviously, you can choose whatever tag names you like and the information you choose to add for effective customer relationship management will be different as well.
