In this chapter we covered the basics of databases, as well as the easiest ways of creating Visual Basic.NET applications to display and manipulate data stored in SQL Server. One of the key points to remember is that correct database construction can have a significant impact on the overall performance and usability of an application. Normalization, referential integrity, and indexing can be very beneficial when applied. However, too much indexing can actually create more work for the database, offsetting the benefit provided. As you go through the next few chapters and consider the business cases presented, keep these points in mind. Questions and Answers
