ReadContainers and WriteContainers /
The name of a ReadContainer is usually the name of the data group that is
the source of the data. The name can be modified but has to be unique.
If this is not the case, a corresponding notification will appear.
The option "Custom class" can be selected as the type here. Any number
of ReadContainers of this type can be created.
Custom Java classes can be integrated here to read data from a specific
database table, for example. More information on this subject is available in our
ReadContainers and WriteContainers
