In this chapter, we introduced the ADO.NET framework, which is a set of classes used to expose the data access services to a developer. ADO.NET contains a set of components to create distribution and data sharing applications. We also discussed the ASP.NET Web API. A web API is a framework to develop HTTP services used by clients or a web browser. A web API collects definitions, procedures, and protocols in order to communicate with different computer software. At the end of chapter, we used AngularJS to retrieve data from the database.

In Chapter 6, Using AngularJS and ASP.NET Web API for CRUD Operations, we will discuss CRUD operations using the ASP.NET Web API and AngularJS.
