How to use rest component
- 1. How to use REST Component 15-12-2014
- 2. Abstract • The main motto of this PPT is How to use REST Component in our applications.
- 3. Introduction • REST stands for Representational State Transfer. REST exposes a much simpler interface than SOAP. REST components are bound with HTTP. So, if you are designing an application to be used exclusively on the Web, REST is a very good option. RESTful applications simply rely on the built-in HTTP security. A REST design is good for database- driven applications and also when a client wants quick integration.
