Summary

Most Visual Basic applications target the business world, and are designed to interact with some sort of database. Understanding the database system used with your application is important; even more important is documenting the specific database features you incorporate into your application.

Because of the influence of relational databases and the SQL language on the database industry, it won't be hard to find a lot of resources to assist you in crafting SQL statements and complex data analysis queries. The Library Project in this book uses SQL Server 2005, but because of the generally consistent use of the core SQL language features, the application could just as easily have used Oracle, Access, or any of a number of other relational databases.
