Whereas in 1.8 almost all functionality was located in the left hand toolbar drawers, in 2.0 you'll find a more intuitive, inline approach to the interface. Simply follow the instructions which accompany each of the menus and wizards. With the addition of relational functionality, there are now multiple tables within a database, each of which contains fields and value lists. The formatting information has now been pushed down to reports . Reports specify a base table or view, but add all the formatting information that had been stored with v1.8 views.
Tabs are groups of fields.
They have names and order, so forms can be constructed with a summary area and a collection of tabs containing additional information. Views only contain derived information from other tables. Tables only contain actual values that are entered or imported by the user. In 1.8, task based security settings were found in the settings dialog. Now access control lists are at the table level.
