-Each data type has its own characteristics and uses:
+The information in Evergreen's database can be classified in nine data types, formats that describe the type of data and/or its use. These were represented by text-only labels in prior versions of Evergreen. Evergreen 3.0 has replaced the text labels with icons. When building templates in _Reports_, you will find these icons in the Field Name Pane of the template creation interface.
