ADO.NET Entity Framework

http://msdn.microsoft.com/en-us/data/aa937723.aspx

A primary goal of the ADO.NET Entity Framework is to raise the level of abstraction available for data programming, thus simplifying the development of data aware applications and enabling developers to write less code. The Entity Framework is the evolution of ADO.NET that allows developers to program in terms of the standard ADO.NET abstraction or in terms of persistent objects (ORM) and is built upon the standard ADO.NET Provider model which allows access to third party databases. The Entity Framework introduces a new set of services around the Entity Data Model (EDM) (a medium for defining domain models for an application).

Webcasts

	Programming LINQ and the ADO.NET Entity Framework (Level 200) Language Integrated Query (LINQ) introduces an exciting new way for applications to build strongly typed queries that are deeply integrated into the programming language. The ADO.NET Entity Framework allows applications and services to work in terms of an application-oriented Entity Data Model, decoupling the application’s data model from the storage considerations of the relational schema. Join this webcast to see how these two technologies work together to change the way applications work with data.
	24 Hours of SQL Server 2008: Using the Microsoft Data Platform for Easy Data Access with SQL Server 2008 (Level 100) Join this series as we look at Microsoft SQL Server 2008 as a productive data platform. Throughout this series, we use Contoso (Container Overseas Shipping Operation) LTD as our scenario customer while we explore the features that make SQL Server 2008 this platform.
	MSDN geekSpeak: Julie Lerman on ADO.NET (Level 200) MSDN geekSpeak is a new kind of webcast series, hosted by Glen Gordon and Susan Wisowaty from the MSDN Events team, that provides a “talk-radio” format where industry experts share their knowledge of and experience with a particular developer technology. In this installment of geekSpeak, Julia Lerman, a Microsoft Most Valuable Professional (MVP), discusses the next version of ADO.NET, which presents a host of new ways to interact with data in your Microsoft .NET applications. Learn how the ADO.NET Entity Framework provides for abstracted access to your data, client views and schemas, and mapping of data to objects. See how you can build queries on the client against your own views and schemas using Entity SQL and Language-Integrated Query (LINQ).
	Framework Masterclass: LINQ to Entities (Level 200) In other sessions, we explored how Microsoft .NET Language Integrated Query (LINQ) is used for Structured Query Language (SQL) databases and working with XML. In this webcast, we connect to the data access layer, the business objects that provide the functionality of working with enterprise data. Join us to learn how you can make your LINQ applications really sing when working with entities.
	Entity Framework for Database Administrators (Level 200) The Entity Framework is a new data technology from Microsoft that may particularly interest database administrators (DBAs). Join this webcast to see how this technology can radically change the development of applications from a DBA perspective, and also change access patterns on servers. We discuss these changes and their impact on DBAs and data developers.

Entity Data Model Tools

http://msdn.microsoft.com/en-us/library/bb399249.aspx

The Entity Data Model (EDM) is a model for defining data as sets of entities and relationships to which common language runtime (CLR) types and storage structures can be mapped. The EDM enables developers to program against a conceptual data model instead of directly against a storage schema.

There are three tools that are designed to help you graphically build applications with the EDM: the Entity Data Model Wizard, the ADO.NET Entity Data Model Designer (Entity Designer), and the Update Model Wizard. These tools work together to help you generate, edit, and update an EDM, as follows:

• The Entity Data Model Wizard allows you to generate an EDM from an existing database, add database connection information to the application, and generate C# or Visual Basic classes based on the conceptual model. When the Entity Data Model Wizard finishes generating an EDM, it launches the Entity Designer.
• The Entity Designer allows you to visually create and modify entities, associations, mappings, and inheritance relationships. You can also validate an EDM with the Entity Designer.
• The Update Model Wizard allows you to update an EDM when changes have been made to the underlying database. You must launch this tool from within the Entity Designer.

There is also a command-line tool designed to help you build applications with the EDM: the EdmGen.exe tool. This tool can generate an EDM, validate an existing model, produce source code files that contain object classes based on the conceptual model, and produce source code files that contain views generated by the model. For detailed information about this command-line tool, see EDM Generator (EdmGen.exe).

ADO.NET Entity Framework

http://msdn.microsoft.com/en-us/library/bb399572.aspx

The ADO.NET Entity Framework is designed to enable developers to create data access applications by programming against a conceptual application model instead of programming directly against a relational storage schema. The goal is to decrease the amount of code and maintenance required for data-oriented applications. Entity Framework applications provide the following benefits:

• Applications can work in terms of a more application-centric conceptual model, including types with inheritance, complex members, and relationships.
• Applications are freed from hard-coded dependencies on a particular data engine or storage schema.
• Mappings between the conceptual model and the storage-specific schema can change without changing the application code.
• Developers can work with a consistent application object model that can be mapped to various storage schemas, possibly implemented in different database management systems.
• Multiple conceptual models can be mapped to a single storage schema.
• Language-integrated query support provides compile-time syntax validation for queries against a conceptual model.
