Abstract: Embodiments of the present disclosure provide a query paradigm that enables named function chaining and nesting to create complex query structures for advanced data analytics. Initially, a REST request uniform resource identifier (URI) is received from a REST client or Hypertext Transfer Protocol (HTTP) client at a REST API. The REST query URI comprises a syntax of functions with named parameters as URI path segments over a HTTP GET call and forms a function tree. The REST request URI is communicated to a request parser that converts the REST request URI into a backend query. The backend query normalizes the function tree into a normalized tree in accordance with a structure of a target of the REST request URI. The backend query is utilized to query data form the target of the REST request URI. Data responsive to the backend query is provided to the REST client or HTTP client.
