Classes and objects are the primary items a user sees when building a new query or working with an existing report. Classes allow you to organize objects into topics in much the way you organize documents into file folders. Objects correspond to columns of data in a database table. However, objects can be much more powerful than raw data lists, enabling you to add intelligence such as aggregations, transformations, prompts, and formatting. This chapter focuses on the basics of classes and objects, whereas Chapters 10 and 11 provide information to make your objects more robust.
