Mastering Entity Framework

Overview of this book

<p>Data access is an integral part of any software application. Entity Framework provides a model-based system that makes data access effortless for developers by freeing you from writing similar data access code for all of your domain models.</p> <p>Mastering Entity Framework provides you with a range of options when developing a data-oriented application. You’ll get started by managing the database relationships as Entity relationships and perform domain modeling using Entity Framework. You will then explore how you can reuse data access layer code such as stored procedures and table-valued functions, and perform various typical activities such as validations and error handling. You’ll learn how to retrieve data by querying the Entity Data Model and understand how to use LINQ to Entities and Entity SQL to query the Entity Data Model.</p>

Summary


In this chapter, we saw how we can control the various database connection parameters such as database location, database name, schema, and so on. We also saw how we can use database initializers to use the database initialization strategy that fits our application needs, and finally, we looked at how we can seed some data using database initializers while using the Code First approach.

At this juncture, we know all about setting up the database using the Database First and Code First approaches. The Model First approach is the same as the Code First approach, but we use Visual Entity Designer to create our entities rather than writing POCO classes. We know how we can manage Entity relationships and map them as database relationships; we also know how we can use entity inheritance to manage our domain entities in a better manner. In the next chapter, we will take a look at how we can use LINQ to Entities to query the Entity Data Model.
