We'll focus on the two main options for retrieving and manipulating data. The first is to use an object-relational mapper, or ORM. It maps data from a relational database management system into an object model so you can use familiar object-oriented programming techniques. The other option is to write your own component to manage database interactions and convert to and from the object model. You can do that using a technology called ADO.NET, which we'll look at a little bit later. Let's start off with the ORM solution. A common problem developers had was the gap between the object models used in object-oriented programming and the structures used for data storage. This is called impedance mismatch and a lot of plumbing code was needed to deal with it. To resolve the issue, object-relational…
