REST (REpresentational State Transfer) is a web service architecture that uses HTTP requests to GET, POST, PUT, PATCH, and DELETE data in a stateless manner. It focuses on resources instead of remote procedures. REST examples show making GET requests to retrieve XML data from a URI and using RESTful principles like addressability, connectedness, statelessness, and a homogeneous interface with standard HTTP methods.

4. REST example
• Try GET
• GET /hello HTTP/1.1
• Host: remotty.com
• Accept: text/plain
• Returen
• <ArrayMember
• xmlns=”http://schemas.datacontract.org/2004/07/wcf“

• </ArrayMember>

5. URI
• Uniform Resource Identifier
• http://www.example.com:80 /users/1
?q=abc#title
• (host + port) + path + parameters

6. RESTful URI
• Normal URI
• http://www.iamcorean.net/finduser.jsp?user=mk&age=32
• RESTful URL
• http://www.remotty.com/sports/soccer
• http://www.remotty.com/sports/soccer/players
• http://www.remotty.com/sports/soccer/players/13/skills

7. RESTful Property
• Addressablilty - simple URI
• Connectedness - connected resource
presentation
• Statelessness - for load balance
• Homogeneous Interface - basic methods

8. REST Methods
• POST
• GET
• PUT
• DELETE
• PATCH
