Summary
In this chapter, you learned about using the nullable keyword to ensure that records that have missing values can still be brought, for example, into an application. You added a field to the People database, modified the dbo.people table, created a Person class, made a list of people, built a connection string, entered SQL-related code, and added people to the list from the dbo.people table.
In the next chapter, you will learn about dragging charts into the page and then making them work with some simple tables inside the SQL Server through C# as the language that connects the page and the database.
