We need to define one or more recordtypes. Each recordType consists of fields and (optionally) validation rules.
Left Pane Top – Schema Explorer
Schema organized in an explorer-like fashion. On selecting each node, the views in the right grid are changed accordingly.
This view displays recordtypes, fields or validation rules as per the node selected. Some cells may be editable or non-editable as per the context.
Left Pane Bottom – Field Properties
If a field is selected in the view grid, the left bottom pane displays the field properties. These depend on the data type and connection type in scope.
