About the sample

The sample data service ResourcesSample should be deployed using the instructions in Samples Setup section.

Database and service definitions

This sample scenario is based on a database which stores information about the products of an enterprise. There are separate queries/resources written for specific tasks of the products. Resources are defined in order to access data through REST calls. The resources implemented in the service are listed as followsbelow. 

• Create Product - Use HTTP POST request to insert new products. 
  Resource Path :
product
• product 
  Resource Method : POST

• Update Product - Use HTTP PUT request to update product infomation. 
  Resource Path :
product
• product 
  Resource Method : PUT

• GET Product - Use HTTP GET request to retreive product infomation for a given product code. 
  Resource Path : product/{productCode} 
  Resource Method : GET

• Get All Products - Use HTTP GET request to get all the products. 
  Resource Path :
products
• products 
  Resource Method : GET
  
  
• Delete Product - Use HTTP DELETE request to delete a given product from the database. 
  Resource Path : product/{productCode} 
  Resource Method : DELETE

See Data Services and Resources for details.
