In this chapter, we took a look at how data is stored in RDBMS systems. We saw the shortcomings of using embedded SQL to access the data. We understood what ORM tools are all about and what problems they solve. We examined the history behind Entity Framework. We saw the capabilities of Entity Framework. Finally, we had a brief excursion into the Entity Framework architecture.

In the next chapter, we will actually build our first application based on Entity Framework Code-First.
