Build a Data Access Layer with New Book on the ADO.NET Entity Framework (Press Release)

Entity Framework Tutorial is a new book from Packt that is a clear and concise guide to the ADO.NET Entity Framework and Data Services. Written by Joydip Kanjilal, this book will help users explore the Entity Client data provider and ADO.NET Data Services, and will learn how they work with the Entity Framework.

The ADO.NET Entity Framework is a framework for providing services on data models from Microsoft. It is a new way to build the data access layer of Windows or web applications. It's an Object Relational Mapping (ORM) technology that makes it easy to tie together the data in a database with the objects in an application.

This book starts with introducing the users to the ADO.NET Entity Framework and builds on their skills to speed up their application development by constructing a better data access layer. Users will also learn to write programs against the Entity Data Model to perform CRUD operations with complex data in their applications.

Through this book users will explore the features of the ADO.NET Entity Framework and understand the concepts of entities and their relationship. Users will be able to create an Entity Data Model using the ADO.NET Entity Data Model Designer as well as the EdmGen tool. Developers will learn how to create statements in Entity SQL.

This book targets C# developers who want to create their data access layer in an easier way. This book is out now and is available from Packt. For more information, please visit http://www.packtpub.com/ entity-framework-tutorial/book

Implementing a Generic Data Transfer Object in C#

Hi,

We often use DataSet or DataTable instances or Business Entity instances to pass data through the layers of an application in ASP.NET. The major disadvantage of this approach is that if you decide to change the data container, i.e., any of these three stated above, you need to change your source code here and there. I have authored an article on Data Transfer Object that illustrates how you can implement a generic approach towards passing data through the layers of an ASP.NET application. Please find the article at the following link:

# re: Implementing a Generic Data Transfer Object in C#

Hi Joydip,

The posting looks interestring. I am currently trying to loosely couple my Data Transformation Objects or Entity classes from the back end SQL 2008 database. What mean here is that, if the undrlying data model changes tomoro, I shouldn't have to modify my Entity code to make the adjustments to be in sync with the database.

Is there any attribute driven approach I can take to achieve this? I was wondering what if I store the Properties of my Entitties as Name-Value pairs, which are essentially the database columns and their vaues.

This way the consumer of the Entity object can just parse the data elements without having to fear if I am out of sync with the back nd database or not...your comments are most welcome.

Again, nice job on the posting!
