Model Implementation
SAP UI5 can be implemented through JSON, XML, ODATA models.
JSON Model
Implementation of JSON has a slight edge over other models since it uses a REST interface. REST is a web application interface model through which the client communicates with the server by modifying the state of resources through representations. This interface manipulates the state of resource oriented decomposition of business processes.
CRUD Application and ICF service based on REST and JSON configurations are provided in the development toolkit references. Implementing the REST service using model and DDIC objects and CRUD methods will summarizes the response of the web service.
*CRUD - Create, Read, Update and Delete methods
*REST - REpresentational State Transfer
*ICF - Internet Communication Framework
*JSON - JavaScript Object Notation
