Overview of this book

<p>The ADO.NET Entity Framework is a new way to build the data access layer of your Windows or web applications. It's an Object Relational Mapping (ORM) technology that makes it easy to tie together the data in your database with the objects in your applications, by abstracting the object model of an application from its relational or logical model.<br /><br />This clear and concise book gets you started with the Entity Framework and carefully gives you the skills to speed up your application development by constructing a better data access layer. It shows you how to get the most from the ADO.NET Entity Framework to perform CRUD operations with complex data in your applications.<br /><br />This tutorial starts out with the basics of the Entity Framework, showing plenty of examples to get you started using it in your own code. You will learn how to create an Entity Data Model, and then take this further with Entity types. You will also learn about the Entity Client data provider, learn how to create statements in Entity SQL, and get to grips with ADO.NET Data Services, also known as Project Astoria.</p>

Summary


ADO.NET Data Services are great in the sense that you can expose your application's data as a service. You can then consume it from any application that has support for performing HTTP requests to perform CRUD operations seamlessly. In this chapter, we have had a quick tour of ADO.NET Data Services including its features and benefits. We have also seen the REST-based model of ADO.NET Data Services, and how we can integrate ADO.NET Data Services with the ADO.NET Entity Framework. We have also discussed how to use ADO.NET Data Services to expose data retrieved through an Entity Data Model as a service so that it can be consumed by client applications. We also discussed how to handle exceptions and debug errors that might occur as a result of accessing a data service. This ends our journey towards mastering the ADO.NET Entity Framework. Happy reading!
