00:00:04,887 --> 00:00:07,280
Hi, my name is James.

3
00:00:07,280 --> 00:00:08,450
Entity framework or

4
00:00:08,450 --> 00:00:15,110
simply EF is a type of framework known
as an object relational mapper or ORM.

5
00:00:15,110 --> 00:00:19,870
Using EF for your applications data access
allows you to interact with your data using

6
00:00:19,870 --> 00:00:23,240
the set of entities and
a database context clause.

7
00:00:23,240 --> 00:00:25,680
This keeps you from having
to write SQL queries

8
00:00:25,680 --> 00:00:28,960
in order to interact
directly with the database.

9
00:00:28,960 --> 00:00:32,330
In an earlier treehouse course we
learned about the basics of EF,

10
00:00:32,330 --> 00:00:36,710
but we did that within the confines
of console application.

11
00:00:36,710 --> 00:00:38,658
While that allowed us to
keep the focus on EF,

12
00:00:38,658 --> 00:00:43,030
it didn't give us
a realistic common use case.

13
00:00:43,030 --> 00:00:46,140
This course is designed to do just that.

14
00:00:46,140 --> 00:00:50,625
Show you how to use EF within a web
application developed using Microsoft's

15
00:00:50,625 --> 00:00:53,740
asp.net MVC web framework.

16
00:00:53,740 --> 00:00:57,210
We'll start this course by seeing
how to put our EF entities and

17
00:00:57,210 --> 00:01:01,550
database context classes into
its own class library project.

18
00:01:01,550 --> 00:01:05,470
Then we will add an ASP.NET MVC
project to our solution and

19
00:01:05,470 --> 00:01:08,890
update to use EF code
in the class library.

20
00:01:08,890 --> 00:01:11,955
After updating our web app to retrieve and
persist data.

21
00:01:11,955 --> 00:01:16,290
We'll look at some options for
organizing our data access code.

22
00:01:16,290 --> 00:01:20,910
By the end of this course you will be
able to use EF with ASP.NET MVC to

23
00:01:20,910 --> 00:01:24,550
create powerful data-driven
web applications.

24
00:01:24,550 --> 00:01:27,250
Let's talk about how to get
the most out of this course.

25
00:01:28,250 --> 00:01:32,832
I'm going to assume that you're already
familiar with the basics of ASP.Net MVC,

26
00:01:32,832 --> 00:01:36,460
entity framework, and Visual Studio.

27
00:01:36,460 --> 00:01:41,550
If you're unfamiliar with any of those
topics or maybe you need a refresher,

28
00:01:41,550 --> 00:01:45,360
check the teacher's notes for a list
of Treehouse resources that can help.

29
00:01:45,360 --> 00:01:48,812
This course is designed
to be highly interactive.

30
00:01:48,812 --> 00:01:51,520
Throughout, I'll be
asking you questions and

31
00:01:51,520 --> 00:01:54,610
giving you hands-on coding
exercises to complete on your own.

32
00:01:54,610 --> 00:01:57,860
But don't worry,
you won't be left hanging.

33
00:01:57,860 --> 00:02:02,080
After you've had time to think about
the question or complete an exercise,

34
00:02:02,080 --> 00:02:05,740
I'll share with you the answer or
walk you through my solution.

35
00:02:05,740 --> 00:02:09,430
Also, I'd encourage you to
follow along with each video.

36
00:02:09,430 --> 00:02:14,190
Write the code yourself as I'm
writing it or just after and

37
00:02:14,190 --> 00:02:17,300
take the time to complete each exercise.

38
00:02:17,300 --> 00:02:21,300
Even if you aren't able to come up with
the solution just the act of trying will

39
00:02:21,300 --> 00:02:26,030
help you to learn and retain the material
Before we start working on setting

40
00:02:26,030 --> 00:02:29,710
up our solution, let's take a look
at our web app in its finished form.
