Question 7: You need to choose the appropriate data access technology for the cookbook area of the webapplication.
Which data access technology should you choose?
A. WCF Data Services
B. LINQ to SQL
C. Entity Framework
D. ADO.NET
Correct Answer: A
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 and updating data as XML, and JavaScript Object Notation (JSON), a text-based data
exchange format used extensively in AJAX application.
