A report designer, however, provides the user with a slew of essential tools to exploit the data stored in a database. It allows data to be presented in detail in various ways. One example might be for following time spent on a projet, displaying profits for the last week, or checking to see which is one's most profitable client. Reports can, for example, be used to create invoices ready to be sent. If you are studying a foreign language, they can be used to print a list of vocabulary relating to a given field, or to register your progress in learning that vocabulary. Another idea might be to follow your creations or designs, through the use of a simple database, and then via the Report Designer, creating a type of catalogue or brochure document containing illustrations and text. In other words, Reports can be used for many varied purposes.
