During interview for Crystal Reports Consultant a question may be asked that what are business views and what is their purpose. We write more on this topic in coming posts, lets enjoy the following for now;

Introduced in Crystal reports 10, Business views, enables users to avoid the complexities of the data source by creating a layer on top of the data source layer. That simplifies the complexities of the data joins and fields.
