Restful style data acquisition

Restful is a style of resource positioning and resource manipulation. Not a standard nor a protocol, just a style. Software designed based on this style can be more concise, more hierarchical, and easier to implement mechanisms such as caching.

 

Resources: Everything on the Internet can be abstracted as resources

Resource manipulation: Use POST , DELETE , PUT , GET to manipulate resources using different methods.

      Corresponding to adding, deleting, modifying and querying respectively.
