    Explanation:
    * Scenario: The cookbook functionality is contained within a client-side application that must connect to
    the server using HTTP and requires access to the data using JavaScript.
    * WCF Data Services (formerly known as “ADO.NET Data Services”) is a component of the .NET
    Framework that enables you to create services that use the Open Data Protocol (OData) to expose and
    consume data over the Web or intranet by using the semantics of representational state transfer (REST).
    OData exposes data as resources that are addressable by URIs. Data is accessed and changed by using
    standard HTTP verbs of GET, PUT, POST, and DELETE
    * WCF Data Services uses the OData protocol for addressing and updating resources. In this way, you
    can access these services from any client that supports OData. OData enables you to request and write
    data to resources by using well-known transfer formats: Atom, a set of standards for exchanging andupdating data as XML, and JavaScript Object Notation (JSON), a text-based data exchange format used
    extensively in AJAX application.
