The secret of getting ahead is getting started. The secret of getting started is breaking your complex overwhelming tasks into small manageable tasks, and then starting on the first one—Mark Twain

As you know, design of an application starts with the data. The data design depends on the types of data that your development tool set allows you to use. Since NAV is designed specifically to develop financially oriented business applications, the NAV data types are financially and business oriented, and also have some special features that make it easier to design and develop typical business applications. Furthermore, these same special features can make your applications run faster.

In this chapter, we will cover the data types that you are most likely to use. We will also take an overview of the others. In addition, we will also cover field classes, which are where the special features are enabled.
