Entity Framework training course (code: ENTFRM)

Create Commercial .NET Applications That Use Object /Relational Mapping Using The .NET Framework


SEE MORE COURSES IN THIS CATEGORY

TRAINING COURSE OVERVIEW

Our ADO.NET Entity Framework training course will show you how to apply LINQ data transfer capability for relational databases.  The Entity Framework can be used in a number of ways, be starting with an existing database, creating a model or by creating entities in code.  The data model can be moved up from the physical structure of relational tables to a conceptual model which reflects common business objects.  Using the Entity Framework, developers can map entities to relational data, enabling the creation of new business objects that provide an abstracted layer to isolate applications from naming as well as structural changes in the schema, making it portable to most SQL databases.

AUDIENCE

Developers who wish to create commercial .NET applications that rely on Object / Relational Mapping using the .NET Entity Framework
