18.11. Wrap-Up

This chapter introduced the relational database model, LINQ to SQL and the IDE’s visual programming tools for working with databases. You examined the contents of a simple Books database and learned about the relationships among the tables in the database. You used LINQ and the LINQ to SQL classes generated by the IDE to retrieve data from, add new data to, delete data from and update data in a SQL Server Express database.

We discussed the LINQ to SQL classes automatically generated by the IDE, such as the DataContext class that controls interactions with the database. You learned how to use the IDE’s tools to connect to databases and to generate LINQ to SQL classes based on a database’s schema. You then used the IDE’s drag-and-drop capabilities to automatically generate GUIs for displaying and manipulating database data.
